I am struggling, trying to figure out how to "turn off" the Header of a XamDialogWindow.  I don't know if would be through a style or a property.  My guess would be to use the HeaderTemplate?.

I would like to have a fixed window that cannot be moved.  I have turned set the properties:

CloseButtonVisibility="hidden"

MinimizedButtonVisibility="hidden"

MaximizedButtonVisibility="hidden"

HeaderIconVisibility="hidden"

Thanks for any guidance!
