Hello ,

Our Ribbon was developed based on Microsoft Ribbon guidelines. In the section “Interaction” is described that it is not recommended to remove toll from the ribbon because doing so can cause the ribbon layout to change, making the ribbon presentation unusable. That is why visible property of ToolBase object act as “Enable”

So if want to hide ToolBase object of customer view, you should remove it from the tools collection. You could use code like:

UltraToolbarsManager1.Ribbon.Tabs("ribbon1").Groups("ribbonGroup1").Tools.Remove(UltraToolbarsManager1.Ribbon.Tabs("ribbon1").Groups("ribbonGroup1").Tools("ButtonTool1"))

Also in order not to loose this ToolBase object you could add it to a prive global collection variable and when you need to make this toolBase object visible again, then just insert it to Tools collection of the desired UltraToolbarsManager element.

Please let me know if you have nay further questions.
