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.
