Selecting Tree Nodes

The Tree Node Selection Changed event runs every time a user selects a tree node, either by clicking it once with the mouse or by moving an arrow up and down the nodes. You can place ER that needs to run when a mode is selected on the Tree Node Selection Changed event. The Work Center application uses this feature to load the media object that appears next to the tree with the message information for each node. You can also use this event when you need to protect controls or exits, based on the kind of node that the user selects.
