Hi there!
I've a problem with RadTreeView control. I'd like to create a (rather) big tree (6 levels, with 300 hundred leaves). Every node need to have a checkbox; checkboxes need to be tri-state. The thing is that I need to read the selection (of nodes) from the database, display whole tree and then the selection of leaves (and according parent nodes). Only selected intermediate nodes will have their subtree expanded. So the problem is that while I render the whole tree, the page is starting to run veeery slow (I've checked in FireBug - whole page has 211 kB!!!). I thought that LoadOnDemand would solve my problems, but it's not that easy because sometimes I'll need to have whole tree expanded (every leaf node selected). Any suggestions?

It sounds to me like you are attempting to display a ton of data, which is why the TreeView is running slow. You mention that you attempted to use Load-on-demand - did it actually improve the performance in the cases where you are able to not have all items expanded? I believe if you actually try to fit your design to perhaps not have all of these nodes displayed at once (that's a lot of data for a single control/page to display at once) you should see improvements.

Hi,
I also had the same problem as Rafal. The RadTreeVIew placed on my page has around 500 nodes and it uses tri-state check boxes. The nodes are placed on 15 levels in depth. The tree view is binded at server side and it is very fast if tri-state check boxes are turned off. But when I turn on the tri-state check boxes it become very slow. I think that the combination of many levels in depth and tri-state check boxes is causing the rad tree view to become slow, since I tested the tri-state check boxes on a server side binded tree view with around 500 nodes that are placed on 5 nodes in depth. In this case the tree view is also very fast. Any suggestion on that?

Hello,
The WebService LoadOndemand delivers the best performance. It does not execute the page lifecycle, does not send the ViewState to the server and outputs tidy JSON which saves precious traffic.
For further information check the following articles. Hope this helps.
