ListView.OnItemUpdated Method (ListViewUpdatedEventArgs)


Raises the ItemUpdated event.

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

Protected Overridable Sub OnItemUpdated (
	e As ListViewUpdatedEventArgs

The ItemUpdated event is raised when an item's Update button is clicked or the UpdateItem method is called, after the ListView control updates the item. (An Update button is a button control whose CommandName property is set to "Update".) This enables you to perform a custom routine whenever this event occurs, such as checking the results of the update operation.

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

The OnItemUpdated 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 OnItemUpdated in a derived class, call the base class's OnItemUpdated method so that registered delegates receive the event.
