CommandEventHandler Delegate

.NET Framework (current version)

Represents the method that will handle the Command event.

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

Syntax

public delegate void CommandEventHandler(
	Object^ sender,
	CommandEventArgs^ e
)

Parameters

sender: Type: System::Object^
The source of the event.

e: Type: System.Web.UI.WebControls::CommandEventArgs^
A CommandEventArgs that contains the event data.

Remarks

The Command event is raised when a Button, ImageButton, or LinkButton control is clicked.

When you create a CommandEventHandler delegate, you identify the method that will handle the event. To associate the event with your event handler, add an instance of the delegate to the event. The event handler is called whenever the event occurs, unless you remove the delegate. For more information about event handler delegates, see NIB: Events and Delegates.
