Hi Alex,
It is important what you do in your code behind - the LoadOnDemand event handler of the RadTreeView.
In order to stop the animation, you have to set the IsLoadingOnDemand property to true like so:
Please let us know if this helps you or not. You can also provide a sample demosntrating your issue s that we could investigate in depth.

I think you reply pointed me in the right direction! I marked it as an answer. I was setting isLoadingOnDemand to false, but I think there was a possibility in my code to skip that step. Should be sorted now though. thanks
