OnClientReordering

The OnClientReordering client-side event occurs when the item or items are about to be reordered. 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 reordering

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

• get_offset() - returns -1 if you are moving the item up and 1 if you are moving the item down.

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

• get_domEvent() - returns the DOM event object

The example below shows how to ask the user before moving the item:

JavaScript

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