OnClientDeleting

The OnClientDeleting Client-side event occurs when the item or items are about to be deleted. This event can be cancelled.

The event handler receives two parameters:

1. The instance of the listbox firing the event

2. An event arguments parameter containing the following methods:

• get_items() - returns an array of the items selected for deletion

• get_item() - returns the item that is about to be deleted.

• set_cancel() - lets you cancel the event and prevent items from deleting.

• get_domEvent() - returns the DOM event object

The example below shows how to delete an item after the user clicks OK in the confirmation dialog:

JavaScript

function onClientDeletingHandler(sender, e) {
	if (!confirm("Are you sure?")){   
	 e.set_cancel(true);
}
