Hello Dean Kuga,
The RadToolBar control itself doesn't get the focus by default.
It is its children that receives the focus. So in order to exclude it from the focus scope you could set the "IsTabStop" property to "False" to all children of the RadToolBar control.
By design the value of the "IsTabStop" property of the RadToolBar is not propagated to its children, because this will make "focus related" customizations harder to achieve.
