I have 1 Tab on the Ribbon. Is there a way to hide the text on the Tab or not show it as it looks silly seeing there is only 1 Tab.
You might be able to remove the element hosting the tab items and move up all elements below it with a creation filter, but you would also have to shrink the size of the top dock area control. This might cause problems though, because I think the size of the dock area is verified often, so it might snap back to its old size. You can also try to just remove the element and leave a gap.
Can a creation filter be used to do this?
There is currently no way to hide the tab items in the ribbon. Also, I believe this would go against the Office 2007 UI Guidelines. However, you can submit a feature request for this ability to be available when Office2007UICompatibility is set to False: http://devcenter.infragistics.com/Protected/RequestFeature.aspx.
