Silverlight WrapPanel RadTreeView Cut-Off by 10 pixels

Question

Hello and thanks for your help in advance. I have two panels, one with a series of the buttons and a Telerik RadTreeView boxed by a border, and on the right another border encompassing a grid and some other controls. Everything is sized properly as I resize the page etc however for some reason there are about 10 pixels being cut-off and cannot think of why. If it was a page container issue it would affect the border on the right side of the page. So I'm thinking it must have something to do with the RadTreeView or WrapPanel I'm using. (Boiled-down code is right after the image below)

Answer 1

Didn't have time nor the inclination to look into the underlying template/styling for either the RadTreeView or the WrapPanel. I was able to fix the issue and maintain the layout by simply putting the RadTreeView in it's own row and leaving just the buttons and other controls in the wrap panel. Suppose it is simpler this way anyway.

Definitely must be a bug or compatibility issue with these two controls that will probably go unsolved.
