OnClientNodePopulating

The OnClientNodePopulating client-side event occurs just before child nodes are loaded from a Client DataSource. The event can be canceled.

The event handler receives parameters:

1. The RadNavigation instance that fired the event.

2. Event arguments with functions:

• get_constructor() retrieves the RadNavigation instance that fired the event.

• get_cancel() returns a boolean value indicating whether the call to the Client DataSource was canceled.

• set_cancel() - call this function to specify whether the event should be canceled (true) or not (false).

• get_owner() retrieves an object that is automatically passed to the Client DataSource.
