Occurs when a delete operation is requested, but before the ListView control deletes the item.

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

public:
event EventHandler<ListViewDeleteEventArgs^>^ ItemDeleting {
	void add(EventHandler<ListViewDeleteEventArgs^>^ value);
	void remove(EventHandler<ListViewDeleteEventArgs^>^ value);
}

The ItemDeleting event is raised when an item's Delete button is clicked or the DeleteItem method is called, but before the ListView control deletes the item. (A Delete button is a button control whose CommandName property is set to "Delete".) This enables you to perform a custom routine whenever this event occurs, such as canceling the delete operation.

A ListViewDeleteEventArgs 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 delete operation should be canceled. To cancel the delete operation, set the Cancel property of the ListViewDeleteEventArgs object to true. You can also work with the Keys and Values collections before the values are passed to the data source.

For more information about how to handle events, see NIB: Consuming Events.

The following example shows how to declaratively add an event handler for the ItemDeleting event.
