I have a RadTreeView that is using LoadOnDemand. My ExpandMode is set to ServerSide, but the Loading Message never displays.
If I change the ExpandMode to ServerSideCallback, then the Loading message is displayed in the tree node being expanded, but the OnNodeExpand function is not called and the loading message is left in the tree.
If I disable Ajax, then the loading and callback function all seem to work, but I want to keep Ajax enable to update other parts of the screen.
How can I implement a Loading Message in a RadTreeView when when using server side load on demand and Ajax?
I am using .NET 3.5, c# and the most recent ASP.NET AJAX controls.

Hello Tim,
Loading message is shown when the nodes are populated via AJAX requests - when the ExpandMode is set to either ServerSideCallBack or WebService.
Since you are using a ServerSide expand mode I suggest that you add RadAjaxLoadingPanel on your page and configure the RadAjaxManager to use that panel.
I have prepared a small project illustrating the approach.
Please download it and give it a try.
