When I first installed 2009 Vol 2 CLR 3.5, the expansion images on the WebHierarchicalGrid appeared in design mode, but not when I ran the app. So I installed the service release. Now they don't appear at all. Any help is appreciated. All I did was drop the grid on the page. Screenshot attached
I ended up deleting the grid off the page, closing visual studio, and deleting the ig_res directory out of my project. Then I reopened the project, added the grid (was prompted that a default style set was being created) and the images were restored.
