Change the expander / load on demand visuals

[Mike]

How do I change the expander and load on demand icons on the left hand side of tree items in the RadTreeView?

Thanks,

Mike

Hello Mike,

You can find an article showing how to change the expander of the RadTreeView here.
In order to change the icon that is used when a particular RadTreeViewItem is Loading-On-Demand, you can edit the style of the item via Expression Blend and change the LoadingVisual Grid placed in the ListRootContainer Grid. The described approach is used in the attached project , so give it a try and let us know how it goes.

Best wishes,
