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.

Namespace:   System.Web.UI
Assembly:  System.Web (in System.Web.dll)

Public Overridable ReadOnly Property CanSort As Boolean

Property Value

Type: System.Boolean

true if the operation is supported; otherwise, false. The default implementation returns false.

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.

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 Not selectArgs.SortExpression Is String.Empty Then
    dataView.Sort = selectArgs.SortExpression
End If
