Client side changes are available on the server side after postback. You can use the ClientChanges property of RadTreeView to access them. The ClientChanges property of RadTreeView returns a collection of objects of type ClientOperation. An operation has two properties:

• Item - the item which has been affected by the client operation;

• Type - the type of the operation which is one of the following four cases:

  • Update - when a property is set on the the client through methods such as set_text(), set_value(), enable(), disable(), etc.: treeNode.disable();

  • Remove - when the remove client method is called: treeview.get_nodes().remove(treeNode);

  • Insert - when the add client method is called: treeview.get_nodes().add(treeNode);

  • Clear - when a node with child nodes calls the clear() method: parentNode.get_nodes().clear(). If the parent node has no child nodes, the ClientChanges collection is not altered.

Note
Note that you need to call the trackChanges() and commitChanges() client methods of RadTreeView in order to be able to access the changes on the server via the ClientChanges property.
