ListSourceHelper.ContainsListCollection Method (IDataSource)

 

Indicates whether the specified data source control contains a collection of data source view objects.

Namespace:   System.Web.UI
Assembly:  System.Web (in System.Web.dll)

Public Shared Function ContainsListCollection (
	dataSource As IDataSource
) As Boolean

Parameters

dataSource
Type: System.Web.UI.IDataSource

An IDataSource that specifies the data source control to test for associated data source view objects.

Return Value

Type: System.Boolean

true if the data source control contains a collection of data source view objects; otherwise, false.

Use this method in an implementation of the ContainsListCollection property, passing a reference to a data source control.

The following code example demonstrates the design pattern for a data source class that implements the IListSource methods. The ContainsListCollection property calls the static ContainsListCollection method.

#Region "Implementation of IListSource"

ReadOnly Property ContainsListCollection() As Boolean Implements IListSource.ContainsListCollection
   Get
      Return ListSourceHelper.ContainsListCollection(Me)
   End Get
End Property


Function GetList() As IList Implements IListSource.GetList
   Return ListSourceHelper.GetList(Me)
End Function 'IListSource.GetList

#End Region
