static member ContainsListCollection : System.Web.UI.IDataSource -> bool
Public Shared Function ContainsListCollection (dataSource As IDataSource) As Boolean
Parameters
- dataSource
- IDataSource
An IDataSource that specifies the data source control to test for associated data source view objects.

Examples
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
bool IListSource.ContainsListCollection {
get {
return ListSourceHelper.ContainsListCollection(this);
}
}
IList IListSource.GetList() {
return ListSourceHelper.GetList(this);
}
#endregion
#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
Remarks
Use this method in an implementation of the ContainsListCollection property, passing a reference to a data source control.
