Thanks for writing and for your questions.
You can hide the Options- and ExitButton by accessing them from the property grid of the RadRibbonBar while in the Visual Studio Designer. There are two properties which expose both buttons. You can expand their sub-properties and find the Visibility property and set it according to your preferences.
You can also hide these buttons programmatically the following way:
.radRibbonBar1.OptionsButton.Visibility = Telerik.WinControls.ElementVisibility.Collapsed;
.radRibbonBar1.ExitButton.Visibility = Telerik.WinControls.ElementVisibility.Collapsed;
Hiding the right column in the Application Menu is possible only programmatically. The following code snippet demonstrates how to achieve this:
.radRibbonBar1.RibbonBarElement.ApplicationMenuRightColumnWidth = 0;
I hope this is helpful.
Do not hesitate to write back anytime you have further questions or need assistance.
All the best,
