Q: 

traverse down through a radtreeview

I need to traverse down my radtreeview programmatically. All I have to start with is the root of the tree. I also have to check first if children nodes exist or not. I have done this before in windwos forms but now I have to deal with it in WPF, Telerik RadTreeView control and .NET 4.0. What is the best way to do this? How to I even get to teh first child of the root as it does not give me a method like RootItem.GetChild() or some method to get the treeviewitem by specifying levels.

I need to traverse down the root to see of there are nodes and if found I need to add more nodes to them one by one.
