Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.

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

public:
 static bool ContainsListCollection(System::Web::UI::IDataSource ^ dataSource);

public static bool ContainsListCollection (System.Web.UI.IDataSource dataSource);

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.

Returns

Boolean

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

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.
