Hello
I have a simple ASP.net handler which returns objects via JSON.
I want to use RadTreeView to display nodes corresponding to it.
All works fine, except I cannot find a way to control the icons (plus, minus and spinner) manually.
My JSON objects contain a flag "hasChildren" and the JSON is only one level deep per request.
I can make requests, get child objects, add them to the telerik tree, recursive if needed, etcetera ... but I cannot find how to manually visualize this ajax/loading behaviour and the "hasChildren" flag.
I noticed that the ExpandMode property on a node is related to this.. however I think it is not an option since it is 0 by default = TreeNodeExpandMode.ClientSide
Any help?
