protected virtual void OnSorting (System.Web.UI.WebControls.GridViewSortEventArgs e);

abstract member OnSorting : System.Web.UI.WebControls.GridViewSortEventArgs -> unit
override this.OnSorting : System.Web.UI.WebControls.GridViewSortEventArgs -> unit

Protected Overridable Sub OnSorting (e As GridViewSortEventArgs)

Parameters

e: GridViewSortEventArgs

A GridViewSortEventArgs that contains event data.

Exceptions

HttpException

There is no handler for the Sorting event.

Remarks

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 Handling and Raising Events.

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 Inheritors

When overriding OnSorting(GridViewSortEventArgs) in a derived class, be sure to call the base class's OnSorting(GridViewSortEventArgs) method so that registered delegates receive the event.
