ListView.OnItemCommand Method

Raises the ItemCommand event.

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

protected virtual void OnItemCommand(
	ListViewCommandEventArgs e

The ItemCommand event is raised when a button in an item template is clicked, but before the command is executed. This enables you to perform a custom routine in response to the supplied CommandName or CommandArgument value whenever this event occurs.

The OnItemCommand method is called by the ListView control to raise the ItemCommand event. It is typically used by control developers when extending the ListView class.

Raising an event invokes the event handler through a delegate. For more information, see Raising an Event.

The OnItemCommand method also enables 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 you override OnItemCommand in a derived class, call the base class's OnItemCommand method so that registered delegates receive the event.
