LinkButton::OnCommand Method (CommandEventArgs^)

 

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
)

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.

System_CAPS_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 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.
