ListSourceHelper.ContainsListCollection Method (IDataSource)
.NET Framework (current version)
Indicates whether the specified data source control contains a collection of data source view objects.
Assembly: System.Web (in System.Web.dll)
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.Booleantrue 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
