Thank you for contacting us.
Before getting to your question I would like to mention that the screenshot you provided implies that you are using a standard MS form and a RadRibbonBar. Please note that our team highly recommends you to use a RadRibbonForm instead of the above combination.
The behavior you experience comes from the fact that setting the visibility of the QuickAccessToolBar to collapsed hides the title bar of RadRibbonBar. This comes from the layout of RadRibbonBar and we would do our best to improve it in one of our future releases. The issue is already logged in our Public Issue Tracking System and you will be able to track its status from here.
Currently, I can suggest to hide the QuickAccessToolBar in the following manner:
element.Visibility = ElementVisibility.Collapsed;
.radRibbonBar1.RibbonBarElement.QuickAccessToolBar.Visibility = ElementVisibility.Hidden;
Our team would like to thank you for your feedback. Your Telerik points have been updated.
I hope you find my answer useful. Let me know if you have further questions. I will be more than happy to assists you.
