Using this property in DataSet returns true because the DataSet class contains a collection of collections. Using this property in DataTable returns false because the DataTable class contains a collection of objects.

The following code example demonstrates how to implement the IListSource interface. A component named EmployeeListSource indicates that it does not contain an IList for data binding by returning false from the ContainsListCollection method. For a full code listing, see How to: Implement the IListSource Interface.

Public ReadOnly Property ContainsListCollection() As Boolean Implements System.ComponentModel.IListSource.ContainsListCollection
    Get
        Return False
    End Get
End Property

bool IListSource.ContainsListCollection
{
    get { return false; }
}
