The OnClientItemsRequesting is fired before sending a request to a Web Service for the items to be bound.
The event handler receives two arguments:
Sender–the TagCould object that fired the event.
Event arguments–event arguments object of type Sys.CancelEventArgs, that exposes the following properties and methods:
|get_cancel||Bool||Returns a bool value that indicates whether the event was canceled. True means the event is canceled.|
|set_cancel||bool||Sets a bool value that indicates whether the event will be canceled. Setting true means the event will be canceled.|
|get_context||String||Returns the parameter which will be sent to the Web Service|
|set_context||string||Sets the parameter which will be sent to the Web Service|
In the TagCloud's Web Service online example you can examine how this event can be used.
