Got it working pretty well. Would be nice if documentation actually had some decent text as to the purposes of the mehods rather than just echoing their name using some robo documenter.

OK I somewhat solved my problem by getting rid of the afterselect event and moving the logic to show a new node view on the click event. Now I need to figure out how to do the same with the keyboard as hitting the ENTER key does nothing.

Any suggestions? I'm sort of dead in the water till I figure out how to have select on mouse up not down?

Upon more experimentation, Extended/Single do exactly the opposite of what I want. It is impossible to start a drag by doing mouse down and moving on the node. You must first select the node and then try to drag it in a separate mouse click and it cannot be done in with a single operation. Still the autodrag is not what I want either. I want to start a drag without selecting or activating the node which I think means to somehow not allow the node to be selected or activated till mouse up. The problem with the node being selected before dragstart happens is that selecting the node changes my gridview and now I cannot drag the node into the view that was there since a new node being selected changes the grid view to that node rather than the one that was selected before trying to drag a different node.

Well the sample SamplesExplorer used the MSFT TreeView and not the UltrTree and that was the ONLY sample I could find where a node was not selected until mouse up so that was rather disappointing...let me know if there is a similar UltrTree means to not select a node till MouseUp.

Also, is the only difference between the active node and the selected node in regards to if multiple nodes are selected? In iow, if only one node can be selected, is it also always the active node? If not what else is the difference? Thanks.
