LinkButton::OnCommand Method (CommandEventArgs^)
Raises the Command event of the LinkButton control.
Assembly: System.Web (in System.Web.dll)
Parameters
- e
-
Type:
System.Web.UI.WebControls::CommandEventArgs^
A CommandEventArgs that contains the event data.
The Command event is raised when the LinkButton control is clicked. This event is commonly used when a command name, such as Sort, is associated with the LinkButton control. This allows you to create multiple LinkButton controls on a Web page and programmatically determine which LinkButton control is clicked.

The Command event is raised through the control hierarchy in the form of the BubbleEvent. |
Raising an event invokes the event handler through a delegate. For more information, see NIB: Raising an Event.
The OnCommand 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 OnCommand in a derived class, be sure to call the base class's OnCommand method so that registered delegates receive the event.
The following example demonstrates how to specify and code a handler for the Command event to display which LinkButton control is clicked.
