  • Article

Gets a reference to the specified DataConnection object from the collection by index value.

Namespace:  Microsoft.Office.InfoPath
Assembly:  Microsoft.Office.InfoPath (in Microsoft.Office.InfoPath.dll)

Syntax

'Declaration
Public MustOverride ReadOnly Default Property Item ( _
    index As Integer _
) As DataConnection
    Get
'Usage
Dim instance As DataConnectionCollection
Dim index As Integer
Dim value As DataConnection

value = instance(index)

public abstract DataConnection this[
    int index
] { get; }

Parameters

Property Value

Type: Microsoft.Office.InfoPath.DataConnection
The specified object.

Remarks

After you have set a reference to the DataConnection object that the Item property returns, you can access any of its properties or methods after the object has been cast to the appropriate type for the corresponding data connection. For example, to access the properties and methods of a data connection for submitting a form in e-mail, you must cast the returned DataConnection object to the EmailSubmitConnection type.

Important

Index value of a given data connection is not guaranteed to be the same between versions, or between sessions of opening the same form template in InfoPath and in a Web browser (from an appropriately configured document library on SharePoint Server 2010 running InfoPath Forms Services). To reliably open the same data connection under all conditions, you should open the data connection explicitly by name using the DataConnectionCollection.Item[String] method instead.

This member can be accessed without restrictions.

This type or member can be accessed from code running in forms opened in Microsoft InfoPath Filler or in a Web browser.

Examples

In the following example, the first DataConnection object is retrieved from the DataConnectionCollection, and then cast to the EmailSubmitConnection type.

   // Get the first connection from the 
   // DataConnections collection.
   EmailSubmitConnection myEmailSubmitConnection =
      (EmailSubmitConnection)(this.DataConnections[0]);

   ' Get the first connection from the 
   ' DataConnections collection.
   Dim myEmailSubmitConnection As EmailSubmitConnection = _
      DirectCast(Me.DataConnections(0), EmailSubmitConnection)
