Gets a value indicating whether the DataSourceView object associated with the current DataSourceControl object supports a sorted view on the underlying data source.
public:
virtual property bool CanSort { bool get(); };public virtual bool CanSort { get; }member this.CanSort : boolPublic Overridable ReadOnly Property CanSort As Booleantrue if the operation is supported; otherwise, false. The default implementation returns false.
The following code example demonstrates how to override the CanSort property in a class that extends the DataSourceView class. This code example is part of a larger example provided for the DataSourceView class.
if (!string.IsNullOrEmpty(selectArgs.SortExpression)) {
dataView.Sort = selectArgs.SortExpression;
}
If Not selectArgs.SortExpression Is String.Empty Then
dataView.Sort = selectArgs.SortExpression
End If
A data-bound control can request sorting by adding the Sort field to the DataSourceSelectArguments object passed to the ExecuteSelect method. If a data-bound control requests sorting, but the CanSort property returns false, the data source view throws an exception.
