RadWindow and Application level help

[paul orsillo]

I want to implement application level help by placing a button in the RadWindow control template's PART_HeaderButtonsBorder.

 I placed a RadButton next to the close box (which is the only other button visible in the window frame).

RadWindows are used in several places and I wnat to define a default help command and then let the ViewModel supply the specific help reference.

I defined an interface that caontains a RelayCommand (I am using MVVM lite) and implement the command in the ViewModesl that I want to respond. It seems the Command never gets fired. I am not getting a binding error. The button "clicks" - depresses etc. But nothing gets fired.

Am I on the right track? Is there another way? Is there a way that I can hook into to the telerik WindowlCommands (The class doesn't appear to be defined as partial) with my own command?

Thank you,
 Paul

I figured out my problem.  I had a binding error but somehow it was silent - which seems pretty unusual.
What I described below works. I'm still open to a better - more seamless - way to do it.
