Get coordinates of a given RadTreeViewItem

Hi, I'm trying to figure out how to do this. Is there a method or a property that returns the X and Y coordinates of an item?

Thanks!

EDIT:

I need the coordinates relative to the parent of the RadTreeView and relative to the RadTreeView itself.

Thanks.

I also tried:

Does anybody have an idea?

How can I find the document in DocumentHost programmatically ?

The RadDocking control has properties and methods for working with Tabbed Documents quickly ?
Close/Open etc... Document programmatically.
I would like to perform a LINQ query (or for/foreach) to find the document that implements a particular interface, this is possible?

Example :

    
            private IDebugEditor GetDebugEditor() {  
        
                var res = from w in radDocking.Documents where w is IDebugEditor select w;  
        
                if (res.Count() != 0)  
        
                    return (IDebugEditor)res.First();  
        
                return null;  
        
            }

In the other case(AutoGemerateColumns="false") I have three columns specify and binded to each column;

the results are only visible by row count, the columns data is empty.
