Sandboxed Solutions Object Model Hierarchy

Today’s diagram is probably best considered a work in progress.
We created the following diagram as a prototype, to see if we could use large-scale static graphics as aids for developers to visualize the SharePoint object model hierarchy and the relationships between classes within it. As an experiment, we took the subset of classes available in sandbox solutions, and, starting from a handful of the most important classes, laid out the Microsoft.SharePoint namespace hierarchy.
The results were mixed: we quickly realized that, as recursively nested as the SharePoint object model is, arbitrarily picking starting points (even important classes such as SPWeb and SPList) and presenting a single hierarchical view of the object model from there probably isn’t going to be that useful long-term for developers. Locating a specific class was difficult. Also, in order to conserve space, we omitted the names of the members used to access a class from another class; in doing so, we inadvertently stripped off an important layer of information about the relationship between the classes.
However, the diagram does provide a useful general reference for how the major classes of the SharePoint namespace are structured, so we’re presenting it here as a free download. The diagram is 34” by 44”, and available as a Visio drawing or pdf file. You can download the larger versions in a zip here on the blog. In the comments, tell us what information you’d want to help you visualize a complex object model like SharePoint, be it in a static diagram like this, or an interactive application that enabled you to select what to display.

How to Programmatically Update an ODC File

This post describes how to update ODC files programmatically by using either a SharePoint feature or a console application written in .Net code, or with a PowerShell script. The contents pertain to:

• Microsoft SharePoint Server 2010
• Microsoft SharePoint Server 2010 – Excel Services
• Microsoft SQL Server 2008

Overview of Office Data Connection Files

An Office Data Connection (ODC) file contains connection information about how to connect to a data source and retrieve data for use in various documents such as Microsoft Excel workbooks. Connection information can either be stored in the workbook or in a connection file, such as an (ODC) file (.odc) or a Universal Data Connection (UDC) file (.udcx).

Typically, an ODC file is used while building Excel services reports that fetch data from a data source. As part of the implementation, this report can be deployed in multiple environments such as development, staging, test, and production. Each environment may have a different data source and hence a different connection string. The connection string should be changed in the ODC file as based on the environment it is deployed in. Usually this is a manual step; however this task can be automated. This approach is the topic of this post.

You can update ODC files programmatically by using either a SharePoint feature or a console application written in .Net code, or with a PowerShell script.

With the console application approach, files need to be published on the SharePoint site with some additional code or deployment steps which are not covered in this article. The PowerShell approach takes care of uploading and publishing the ODC file to the SharePoint site.

One ODC file can be used for one or more Excel files. ODC files contain the following types of information:

• Connection string
• Command Type
• Command Text
• SSO Application ID
• Credentials Method
• Whether to always use the connection file

Description of an ODC File

An ODC file is a HTML file that contains embedded sections of XML. The XML in an ODC file determines the core connection information for the data source. This information includes:

• Data provider-specific connection string that is used to establish and open a connection to the data source
• Query text that is used to fetch data
• Name of the specific table or cube from which to fetch data
• Hints about how the query text, cube, or table name is interpreted
• Flag indicating that the ODC file is always used to connect to and query the data source (as opposed to an application using a cached version of the data connection information)
• Specific authentication information to use for the data source. If a server application is using the ODC file to fetch data, this information will often be used for connecting to the data sources

The following HTML is an example of an ODC connection string inside of an ODC file:

<odc:OfficeDataConnection xmlns:odc="urn:schemas-microsoft-com:office:odc" xmlns="http://www.w3.org/TR/REC-html40">
<odc:Connection odc:Type="OLEDB"> <odc:ConnectionString>Provider=SQLOLEDB.1;Integrated Security=SSPI;Persist Security Info=True;Initial Catalog=<Database Name>;Data Source=<Database Server>;Use Procedure for Prepare=1;Auto Translate=True;Packet Size=4096;Workstation ID=<Computer Name>;Use Encryption for Data=False;Tag with column collation when possible=False</odc:ConnectionString>
<odc:CommandType>SQL</odc:CommandType>
<odc:CommandText> &quot;<Database Name>&quot;.&quot;dbo&quot;.&quot;<Stored Procedure Name>&quot;</odc:CommandText>
<odc:SSOApplicationID>ExcelServicesApplicationID</odc:SSOApplicationID>
<odc:CredentialsMethod>Stored</odc:CredentialsMethod>
<odc:AlwaysUseConnectionFile/>
</odc:Connection>
</odc:OfficeDataConnection>

A C# Code Example

The following is a simple console application that shows how to change values inside an ODC file. This code can be used in a feature or a console application with all the previous parameter values provided from a configuration file. This code changes the highlighted values in the data connection XML shown above.

namespace UpdateODCFile
{
using System.Linq;
using System.Text;
using System.Xml;
/// <summary>
/// Class to change the ODC file parameters
/// </summary>
class Program
{
/// <summary>
/// Index from where tag begins
/// </summary>
private static int sourceIndex = 0;
/// <summary>
/// Index from where tag ends
/// </summary>
private static int destinationIndex = 0;
static void Main(string[] args)
{
// You can keep the source an destination file path same if you want to
// overwrite the existing file with new values.
string odcFilePath = @"C:\Reports\Connection.odc";
string destinationFilePath = @"C:\Reports\Connection.odc";
// Provide values for following patameters that will be changed in the ODC file.
string databaseName = "<your database name>";
string serverName = "<your server name>";
string SSOApplicationID = "<application ID>";string provider = "<Provider>";
string integratedSecurity = "<integrated security>";
string persistSecurityInfo = "<persist security info>";
string useProcedure = "<use procedure>";
string autoTranslate = "<auto translate>";
string packetSize = "<packet size>";
string workSatationID = "<workstation ID>";
string encryptionData = "<encryption data>";
string tagWithCollation = "<tag with column collation>";
The following code reads the ODC file and retrieves the ODC connection XML data from it.
string xmlConnection = GetConnectionString(odcFilePath);
XmlDocument odcXmlConnection = new XmlDocument();
odcXmlConnection.LoadXml(xmlConnection);
XmlNamespaceManager nameManager = new XmlNamespaceManager(odcXmlConnection.NameTable);
nameManager.AddNamespace("odc", odcXmlConnection.DocumentElement.NamespaceURI);
XmlNodeList nodelistConnectionString = odcXmlConnection.SelectNodes("//odc:Connection/odc:ConnectionString", nameManager);
The following code changes the connection properties mentioned above.
StringBuilder finalConnectionString = CreateNewConnectionString(databaseName, serverName, provider, integratedSecurity, persistSecurityInfo, useProcedure, autoTranslate, packetSize, workSatationID, encryptionData, tagWithCollation, nodelistConnectionString);
nodelistConnectionString[0].InnerText = finalConnectionString.ToString();
The following code changes the SSOApplicationID property in the XML.
XmlNodeList nodelistSSOApplicationID = odcXmlConnection.SelectNodes("//odc:Connection/odc:SSOApplicationID", nameManager);
nodelistSSOApplicationID[0].InnerText = SSOApplicationID;
The following code saves the updated file on to a disk. When this is complete, the file can be published to SharePoint.
SaveConnectionString(odcFilePath, destinationFilePath, odcXmlConnection.OuterXml);
}
The following code finds the connection string tag in the ODC file and returns the full connection string.
/// <summary>
/// Finds the connection string in the ODC file
/// </summary>
/// <param name="filePath">path of ODC file</param>
/// <returns>office data connection xml</returns>
public static string GetConnectionString(string filePath)
{
   string xmlConnection = string.Empty;
   System.IO.StreamReader myFile = new System.IO.StreamReader(filePath);
   string myString = myFile.ReadToEnd();
   sourceIndex = myString.IndexOf("<odc:OfficeDataConnection");
   destinationIndex = myString.IndexOf("</odc:OfficeDataConnection");
   xmlConnection = myString.Substring(sourceIndex, destinationIndex - sourceIndex + 27);
   myFile.Close();
   return xmlConnection;
}
The following code saves the connection string tag to the ODC file and saves it to a disk.
/// <summary>
/// save the changed ODC file
/// </summary>
/// <param name="filePath">path at which you want to read the ODC file</param>
/// <param name="newFilePath">path at which you want to save</param>
/// <param name="connectionString">new data connection string to be changed</param>
public static void SaveConnectionString(string filePath, string newFilePath, string connectionString)
{
   string xmlConnection = string.Empty;
   System.IO.StreamReader myFile = new System.IO.StreamReader(filePath);
   string myString = myFile.ReadToEnd();
   myFile.Close();
   string lessString = myString.Remove(sourceIndex, destinationIndex - sourceIndex + 27);
   myString = lessString.Insert(sourceIndex, connectionString);
   System.IO.StreamWriter writer = new System.IO.StreamWriter(newFilePath);
   writer.Write(myString);
}
The following code finds the properties in the ODC file and then changes them. If a property does not require any changes, it can be removed from this code. The new connection string will be returned to the Main function.
/// <summary>
/// Function to replace the old values with new one.
/// </summary>

private static StringBuilder CreateNewConnectionString(string databaseName, string serverName, string provider, string integratedSecurity, string persistSecurityInfo, string useProcedure, string autoTranslate, string packetSize, string workSatationID, string encryptionData, string tagWithCollation, XmlNodeList nodelistConnectionString)
{
   string[] connectionStringArray = nodelistConnectionString[0].InnerText.Split(';');
   StringBuilder finalConnectionString = new StringBuilder();
   foreach (string connections in connectionStringArray.ToList())
   {
      string[] splitOnEqual = connections.Split('=');
      switch(splitOnEqual[0])
      {
         case "Initial Catalog": splitOnEqual[1] = databaseName;
         break;
         case "Data Source": splitOnEqual[1] = serverName;
         break;
         case "Provider": splitOnEqual[1] = provider;
         break;
         case "Integrated Security": splitOnEqual[1] = integratedSecurity;
         break;
         case "Persist Security Info": splitOnEqual[1] = persistSecurityInfo;
         break;

         break;
         case "Packet Size": splitOnEqual[1] = packetSize;
         break;
         case "Workstation ID": splitOnEqual[1] = workSatationID;
         break;
         case "Use Encryption for Data": splitOnEqual[1] = encryptionData;
         break;
         case "Tag with column collation when possible": splitOnEqual[1] = tagWithCollation;
         break;
      }
      finalConnectionString = finalConnectionString.Append(splitOnEqual[0]);
      finalConnectionString = finalConnectionString.Append("=");
      finalConnectionString = finalConnectionString.Append(splitOnEqual[1]);
      finalConnectionString = finalConnectionString.Append(";");
   }
   finalConnectionString = finalConnectionString.Remove((finalConnectionString.Length-1), 1);
   return finalConnectionString;
}
}
}

Code Example using a PowerShell

The following is a PowerShell script to accomplish the same task described previously.

Conclusion

This post explained how to write code to update ODC files programmatically. This approach can be used to update the ODC files when moving them from one environment to another. The PowerShell script can be useful for automated deployment of ODC files.

How to set automatically focus on ASP.NET controls when validation fails ?

If you are using ASP.NET Validation Control then you can use “SetFocusOnError” properties to automatically focus the control if validation fails. This will help the end user to identify the control easily.
To set focus automatically you  have to set SetFocusOnError=”True”. By default it’s false. SetFocusOnError  of a validation control is associated with “ControlToValidate” properties. If the validation fails, focus will automatically  move to the control which is specified in ControlToValidate.


Now in such case where multiple validation fails at same time then first validation will get the focus.
Hope this will help you !
Cheers !

Programmatically Create a Managed Metadata List Column (Mohammed Faizan)

Managed metadata is a hierarchical collection of centrally managed terms that you can define, and then use as attributes for items in Microsoft SharePoint Server 2010. Refer here for more information on the managed metadata in SharePoint 2010.
A column is a location in a list in which to store information about a SharePoint Server 2010 item. When you define a column, you provide a name for the column, specify the column's type, and provide additional information that depends on the column type.
SharePoint Server 2010 introduces a new column type named managed metadata. When you create a managed metadata column, you specify the term set from which the column's values must come. When you want users to provide information for list items (including documents), and the valid values for the information are contained in a term set, use a managed metadata column. Create a new content type or modify an existing content type, and then add the managed metadata column to the content type.
This post describes the way of programmatically creating a managed metadata taxonomy column and adding the column to a custom content type.
In this article, you:

1. Create a SharePoint 2010 project
2. Add a feature and feature receiver
3. Add code to create a managed metadata site column and then add the site column to a custom content type
4. Deploy the solution to SharePoint 2010

The code in this topic creates a TaxonomyField class which was introduced in SharePoint 2010. The TaxonomyField class is a custom field class that inherits from the SPFieldLookUp class. Refer here for more on the TaxonomyField class.

Programmatically Create the Managed Metadata Column

The following steps deploy the code to SharePoint 2010 as a feature receiver that programmatically creates the managed metadata column. The procedures in this section assume a development environment where SharePoint 2010 is installed and configured, Microsoft Visual Studio 2010 is installed, and the currently logged-in user has administrative rights on the SharePoint environment for deployment purposes.
Before you begin, ensure that you have the Managed Metadata service provisioned and Term sets and terms created. Figure 1 shows the terms set and terms.
Figure 1. Term set and terms

1. In Visual Studio 2010, click New Project, expand the SharePoint node, click 2010, and then click Empty SharePoint Project. Provide name for the project.
2. In the SharePoint Customization Wizard, select the local SharePoint site that will be used for debugging. Select the Deploy as a farm solution option and then click Finish.
Note: Creating a TaxonomyField class requires a reference to the Microsoft.SharePoint.Taxonomy.dll. This .dll is not available in a sandbox solution and therefore the solution will have to be deployed as a farm solution.
3. In Solution Explorer, right-click the Features node, and then click Add Feature as shown in Figure 2.
Figure 2. Add the feature

4. Name the feature AddMMSColumn and add a description as shown in Figure 3. Change the Scope to Site.
Figure 3. Define the feature

5. Right click the AddMMSColumn feature node and then click Add Event Receiver. (see Figure 4).
Figure 4. Add an event receiver

6. Add the following code in the feature receiver’s FeatureActivated event.
public override void FeatureActivated(SPFeatureReceiverProperties properties)
{
   const string TermStoreName = "Managed Metadata Service";
   const string GroupName = "Office Locations";
   const string TermSetName = "Europe";
   const string SPLocationListColumn = "OfficeLocation";
   const string ContentTypeOfficeDetails = "Office Details";
   //Get the Taxonomy session for current SPSite
   TaxonomySession session = new TaxonomySession(SPContext.Current.Site);
   if (session.TermStores.Count != 0)
   {
      using (SPSite site = (SPSite)properties.Feature.Parent)
      {
         SPWeb rootweb = site.RootWeb;
         var termStore = session.TermStores[TermStoreName];
         var group = from g in termStore.Groups where g.Name == GroupName select g;
         var termSet = group.FirstOrDefault().TermSets[TermSetName];
         //Get the content type to which the taxonomy field is to be added
         SPContentType contentTypeOfficeDetails = rootweb.ContentTypes[ContentTypeOfficeDetails];
         //Check if field exists, if yes take no action
         bool fieldExists = rootweb.Fields.ContainsField(SPLocationListColumn);
         if (!fieldExists)
         {
            //Create a new TaxonomyField
            TaxonomyField field = rootweb.Fields.CreateNewField("TaxonomyFieldType", SPLocationListColumn) as TaxonomyField;
            field.SspId = termSet.TermStore.Id;
            field.TermSetId = termSet.Id;
            field.TargetTemplate = string.Empty;
            field.AllowMultipleValues = true;
            field.CreateValuesInEditForm = true;
            field.Open = true;
            field.AnchorId = Guid.Empty;
            field.Group = "Taxonomy Fields";
            //Add the taxonomy field to site columns
            rootweb.Fields.Add(field);
            rootweb.Update();
            TaxonomyField fieldAdded = rootweb.Fields[SPLocationListColumn] as TaxonomyField;
            //Add the field to the a custom content type
            SPFieldLink fieldLnkArticle = new SPFieldLink(fieldAdded);
            contentTypeOfficeDetails.FieldLinks.Add(fieldLnkArticle);
            contentTypeOfficeDetails.Update(true);
         }
      }
}
7.  Right click the project name in Visual Studio and then click Deploy as shown in Figure 5.
Figure 5. Deploy the solution

8.  Navigate to the site where the feature is activated. Click Site Settings and then click Site columns. The newly created column is visible in the Taxonomy Fields group as shown in Figure 6.
Figure 6. The newly create column

9.  Click the column name to go to the Edit page of the column. The term set that was specified in the code should be selected as shown in Figure 7.
Figure 7. The highlighted term set

10. Click Site Settings and then click Site content types. Click the content type to which the column was added. The column is visible in the Manage content type page of the selected content type (see Figure 8).
Figure 8. The new column

You can start using this content type or the column in your lists and libraries.

SharePoint Developer Tools in Visual Studio 11 Beta – Part III: Tips and Tricks in SharePoint List Designer

the Part I of this series, we were pleased to announce the SharePoint List Designer as one of the new features introduced in Visual Studio 11 Beta. Using the List Designer, you can quickly and visually build a SharePoint list within Visual Studio without having to create a list first in SharePoint Designer and then import it into Visual Studio.
To familiarize you with the List Designer, in Part I of this series, we provided a link to a MSDN Help topic that walks you through the process of creating a list and a content type by using the List Designer. If you’ve used the List Designer, you might want more details about its functionality. This blog post provides more information about it.

SharePoint 2010: Add button to Ribbon with SharePoint designer

Sometimes you may need to add buttons to SharePoint 2010 ribbon. You can take one of two approaches: You can write code to add the button. Another approach is to use SharePoint Designer to add button to Ribbon. Today I’ll show you how to add button to Ribbon using SharePoint Designer. However, when you’ll use SharePoint Designer to add button to Ribbon and if you do  so in Development or Staging server, then think about how to do the same in Production server.

Add Button to List/Library forms (AllItems.aspx, DispForm.aspx, EditForm.aspx, NewForm.aspx)

Let’s say you have a list and you want to add a new Ribbon button in the AllItems.aspx page.

1. First open the site in SharePoint Designer.

2. Then click “List and Libraries” link from the left-hand menu and then click the target list from the details page on the right hand side as shown below:

Figure 1: Select List/Libraries in SharePoint Designer

3. Once you click the list name you’ll be landed to the list/library settings page. In this page you can edit four forms (AllItems.aspx, DispForm.aspx, EditForm.aspx and NewForm.aspx) and you can add button to the page’s ribbon. The page is shown below:

 

Figure 2: Four built-in Forms

4. From the ‘List Settings’ tab on the top, select ‘Custom Action’ as shown below:

Figure 3: Add custom Action

5. Say you want to add button to ‘NewFom.aspx’. For this click ‘New Form Ribbon’ from the Custom Action. You’ll get the ‘Create Custom Action’ window where you can add custom action to the Ribbon. From the window below you can chose one of three different actions: Navigate to form, Initiate workflow, Navigate to Url. If you need more custom action then SharePoint Designer will not be helpful. You need to write code to extend Ribbon button actions.

Figure 4: Custom Action Properties

Find Ribbon Location:

In the List/Library form, the button are placed in groups. As shown in the image below, the new form has three sections:

Figure 5: Buttons are placed in Groups/Sections in form

Now you may want to place your button in a particular group and for that you need know the location id so that you can put the id in the ‘Ribbon Location’ in the custom action properties in SharePoint Designer. Using Firebug extension of Mozilla Firefox, I have found the ribbon location id as shown below:

Figure 6: Ribbon group/section id (detected using Firebug extension of Firefox)

So now you can put the ribbon location id in the custom action properties. For example to put the ‘Show Me’ button in the ‘Commit’ section I have put the ribbon button location to ‘Ribbon.ListForm.Edit.Commit.Controls._children’. Here the ‘.Controls._children’ is added to the ribbon id. The following figure show two windows side by side:

Figure 7: Custom Action windows (On Left) and New Item Form (On right) with ‘Show Me’ button

Decide when to show the Ribbon Button

Sometimes you don’t want to show the button for all users. Rather you want to show for users having a set of permissions. The ‘Rights mask’ option allow us to meet this requirements. The available values can be found on MSDN. You can put more than one values in the Rights Mask text box separated by semicolons as shown below:

Figure 8: Rights mask

Define Ribbon button sequence in a group

You can determine the ribbon button location in a group/section by setting the ‘sequence number’. I have not found documentation about the sequence number but I have found by myself that each position holds 10. So giving 10 in that filed will show as the first button. Putting any value more than 10 but less than 20 will show as second button and so on.
