OnClientItemsRequesting

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:

Name	Parameters	Return Type	Description
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.
