GridView.OnSorting Method
Raises the Sorting event.
Namespace: System.Web.UI.WebControls
Assembly: System.Web (in System.Web.dll)
Parameters
- e
- Type: System.Web.UI.WebControls.GridViewSortEventArgs
A GridViewSortEventArgs that contains event data.
| Exception | Condition |
|---|---|
| HttpException | There is no handler for the Sorting event. |
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.
Raising an event invokes the event handler through a delegate. For more information, see Raising an Event.
The OnSorting 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.
Notes to InheritorsWhen overriding OnSorting in a derived class, be sure to call the base class's OnSorting method so that registered delegates receive the event.
