I don't see anything in the docs but it seems like a standard thing to have.
What I'm looking for - the user will perform an action on a node in my TreeView which will result in a call to a remote API that can (sometimes) take several seconds. I'd like to disable the TreeView or set it to loading so that the user knows there is some activity and to also prevent interaction with the TreeView.
What's the Kendo way to do this? I can overlay a "busy" div but I'd like it to be visually close to the Grid loading appearance.
