Since the XControl is only being used in my application and in one spot I was able to fudge a little and use the following code. Note the plus 10 which I think is due to splitters or panes not being at origin. I think NI also has a similar issue with their tip strips that has been documented. If you hover over control that is in a paned window that is in a subpanel you will see it. The location of the tip strip can vary and to get it in the correct place you have to scroll the pane. Maybe this is fixed in 2012, but haven't switched from 2011SP1 yet so I'm unsure. Anyway here is the code that seemed to work good enough for me to get by.
