I’ve implemented the RadTreeView with load on demand using ExpandMode = ServerSideCallback. I’ve also implemented context menus to allow users to add nodes dynamically. The problem I’m having is figuring out how to render the tree and expand to the newly added node. Since the load on demand only loads the top level nodes, the added node won’t be visible on postback in cases where the new node is a couple of levels deep.
I would appreciate any suggestions.
Also, I’ve implemented drag and drop which is going to be a problem too. So any suggestion for that would be helpful too.
