We have a RadTreeListView
where the IsExpanded property of the rows is bound to a property on row
objects. Sometimes, some of the expander triangles in the RadTreeListView
look expanded, but their children are not visible. Any idea what might be
causing this or how to fix it?
The attached image shows a small example. The third row looks like it's expanded, but its child is not shown. If you click the triangle, it collapses it; and if you click it again, it's then expanded properly with the child shown.
