The GridView.Sorting event is raised when the hyperlink to sort a column is clicked, but before the System.Web.UI.WebControls.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.

Raising an event invokes the event handler through a delegate. For more information, see Raising an Event.

The GridView.OnSorting(GridViewSortEventArgs) method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.
