GridView::Sorting Event
Updated: April 2009
Occurs when the hyperlink to sort a column is clicked, but before the GridView control handles the sort operation.
Assembly: System.Web (in System.Web.dll)
The Sorting event is raised when the hyperlink to sort a column is clicked, but before the GridView control handles the sort operation. This enables you to provide an event-handling method that performs a custom routine, such as canceling the sorting operation, whenever this event occurs.
A GridViewSortEventArgs object is passed to the event-handling method, which enables you to determine the sort expression for the column and to indicate that the selection operation should be canceled. To cancel the selection operation, set the Cancel property of the GridViewSortEventArgs object to true.
For information about how to programmatically initiate a sort operation, see the Sort method.
For more information about handling events, see Consuming Events.
The following example demonstrates how to use the Sorting event to perform the sorting functionality when the GridView control is bound to a DataTable object by setting the DataSource property programmatically.
