OnClientTileDropped

The OnClientTileDropped event is raised after a tile is dropped by the user in the browser. It is not cancellable.

The event handler receives two arguments:

1. the RadTileList object that fired the event

2. an event arguments object that exposes the following methods

OnClientTileDropped event arguments object

Name	Return type	Description
get_tile()	RadBaseTile client-side object	Gets a reference to the tile that is dropped.

The following example will show how the OnClientTileDropped event can be used to prompt the user to save the changes that are made to the layout. The full version would require a RadWindowManager for the confirmation dialog, a RadAjaxManager for the request to the server and a RadPersistenceManager to save the state.
