not even sure I want to actually cancel the nodepopulating event yet, but I'll explain what I'm attempting:
I have a radtreeview, with it's nodes being populated by a webservice when expanded. As it turns out, one of the nodes has a LOT of children, and even taking into consideration an extra level of nodes, to perhaps break the subnodes down by alphabetical order, it doesn't look like the most usable way of selecting nodes under that category, not to mention very slow to return so many nodes.
So, what was considered is something along the lines of canceling the particular nodePopulating event (although I guess the better approach is to change the TreeNodeExpandMode for that node in the first place - I think I just answered my own question), and instead of loading the nodes instantly, display a textbox, where the user can start typing the first letters of the required child node, at which point the nodes under that category will filter based on the user's text entry. I can imagine this being an ajax style predictive text box, but perhaps this isn't that important - the key thing is not actually populating children for this node until the user has entered some text into a textbox to filter the list.
Sound possible?
