ListView::ItemEditing Event
Updated: February 2010
Occurs when an edit operation is requested, but before the ListView item is put in edit mode.
Assembly: System.Web.Extensions (in System.Web.Extensions.dll)
The ItemEditing event is raised when an item's Edit button is clicked, but before the ListView item is put in edit mode. (An Edit button is a button control whose CommandName property is set to "Edit".) This enables you to perform a custom routine whenever this event occurs, such as canceling the edit operation.
A ListViewEditEventArgs object is passed to the event handler, which enables you to determine the index of the current item. It also lets you indicate that the edit operation should be canceled. To cancel the edit operation, set the Cancel property of the ListViewEditEventArgs object to true.
For more information about how to handle events, see Consuming Events.
The following example shows how to add an event handler for the ItemEditing event.
