currently no wrappers exist for the RadTreeList control. It's possible to treat the TreeList as a GridView in order to navigate it. However, some of the functionality assoicated with GridView will not be functional. For instance if you get a Row which is a part of a TreeList attempting to access its cells from the Cells property won't work. Here's a piece of code that navigate the TreeList view found here:
row = 0;
GridViewRow gg1 = ggg.As<GridViewRow>();
+ row.ToString() +
cell = 0;
Let me know if you require additional assistance with getting this to work.
