Using the Q3.2009 release, I built a treeview dynamically in code. I create treeview items and set them to a shared BitmapImage depending on the type of data object that the treeviewitem represents. Everything worked fine.
When I upgraded to the Q1.2010 release, the treeview no longer displays the images. They display correctly in my OutlookBar and RadContextMenus, but not the treeview. I create them with code like the following:
var newItem = new RadTreeViewItem();
newItem.Header = item.Group.Identity.Description;
newItem.DefaultImageSrc = item.Group.GroupIcon.SmallIcon;
where SmallIcon is of Type BitmapImage containing a 16 x 16 image from a png file.
I didn't see anything mentioned in the treeview changes list for Q1.2010 but something is different.
Any ideas what I need to change to get the images to show in the treeview?
