See the attached sample.
Changing the visibility to Collapsed on the QuickAccessToolbar doesn't do anything. I don't want the white space there above the tabs in the XamRibbon.
Note: Another application that also uses the XamRibbon properly hides that line. The only difference is that the other project uses XamRibbonWindow, but I can't use that in my case.
Hello Jon Heaton,
In order to remove the white space above the tabs, "rootVisual" Grid element should be get from the visual tree of the XamRibbon. Infragistics has Utilities class that has methods for getting an element by name and type. After the grid element is found, its first row definition's MinHeight should be set to 0.0. Please keep in mind that still there be some very little white space above the tabs. That is the Separator. By using the Utilities class, the separator's Visibility is set to Collapsed.
Please take a look at the attached sample and let me know if you have any other questions on that matter.
Thank you for using Infragistics controls!
