I need to display a hierarchy with checkboxes. For this I want to use TreeView. After the hierarchy finishes loading I have to do some actions. So the TreeView is configured with LoadOnDemand: false and a function is attached to the "dataBound" event. However it seems that the data bound is called after every call to the server. Is there an event that is triggered after all the nodes have been loaded? How can I know that the databound is the last one (all the nodes have been loaded)?
