DataSourceView.CanSort Property


Gets a value indicating whether the DataSourceView object associated with the current DataSourceControl object supports a sorted view on the underlying data source.

 virtual property bool CanSort { bool get(); };
public virtual bool CanSort { get; }
member this.CanSort : bool
Public Overridable ReadOnly Property CanSort As Boolean

Property Value

true 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.
