LinkButton.OnCommand Method

Raises the Command event of the LinkButton control.

Namespace: System.Web.UI.WebControls
Assembly: System.Web (in system.web.dll)

protected:
virtual void OnCommand (
	CommandEventArgs^ e
)
protected void OnCommand (
	CommandEventArgs e
)
protected function OnCommand (
	e : CommandEventArgs
)
Not applicable.

Parameters

e

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.

NoteNote:

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 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.
