The OnClientNodeCollapsed client-side event occurs after the user clicks the collapse (minus) button.

The event handler receives parameters:

1. The treeview instance that fired the event.

2. Event arguments with functions:

   • get_node() retrieves a reference to the clicked on node.

   • get_domEvent() retrieves a DOM event object of the node collapsing.

The example below demonstrates retrieving a reference to the collapsed parent node.
