Hi Srinivas,
The
RibbonBackstage ControlTemplate contains a
ScrollViewer and the content of each
RadRibbonBackstageItem is wrapped in this
ScrollViewer. However as the
ScrollViewer measures its
Children size with infinity, the layout of your content is different than if it's wrapped in another panel like
Grid.
I am not sure how you would like to layout the
BackstageItem content and this is why I'm not sure if removing the
ScrollViewer will help, but please give it a try. You need to edit the default
ControlTemplate of the
RibbonBackstage - if you're using the default theme of the control, you can extract the template from Blend, otherwise you can find it in the
Themes folder under your installation directory.
In
this forum thread you can find projects demonstrating how to remove the
ScrollViewer element from the
RibbonBackstage.Template in the
OfficeBlack default theme and the
Windows7 theme.
