GridView::OnRowCommand Method (GridViewCommandEventArgs^)
Raises the RowCommand event.
Assembly: System.Web (in System.Web.dll)
Parameters
- e
-
Type:
System.Web.UI.WebControls::GridViewCommandEventArgs^
A GridViewCommandEventArgs that contains event data.
The RowCommand event is raised when a button is clicked in the GridView control. This enables you to provide an event-handling method that performs a custom routine whenever this event occurs.
Raising an event invokes the event handler through a delegate. For more information, see NIB: Raising an Event.
The OnRowCommand 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 OnRowCommand in a derived class, be sure to call the base class's OnRowCommand method so that registered delegates receive the event.

The following example demonstrates how provide an event-handling method for the RowCommand event. When the Add button is clicked for a given row of the GridView control, the name of the selected customer is added to a ListBox control.
