Set RadRibbonBar in Titlebar Mode
In order to remove the tabstrip part of RadRibbonBar and leave only the titlebar part visible (together with the Start button, and QuickAccess menu), you need to set the following properties:
TitleBar Mode
this.radRibbonBar1.RibbonBarElement.TabStripElement.Visibility = Telerik.WinControls.ElementVisibility.Collapsed;
this.radRibbonBar1.StartButtonImage = new Bitmap(this.radRibbonBar1.StartButtonImage, new Size(15, 15));
Me.RadRibbonBar1.RibbonBarElement.TabStripElement.Visibility = Telerik.WinControls.ElementVisibility.Collapsed
Me.RadRibbonBar1.StartButtonImage = New Bitmap(Me.RadRibbonBar1.StartButtonImage, New Size(15, 15))
The result is shown on the screenshot below:
