RibbonBar Group Visibility problem

[Beshoy]

Hi ,
I have a problem.
I want to hide radribbon group bar in code behind according to user roles
I applied this technique : 
RadribbonGroupbarControl.visible = false;
It works but hide all Radribbon Groupbar Controls , but after clicking between two tabs for a while it appears again.
Thanks In Advance.

Hi Beshoy,

Please have a look at the following C# code I tried which works fine at my end.

C#:

RibbonBarGroup g1 = RadRibbonBar1.FindGroupByValue("RibbonBarGroupValue");
g1.Visible = false;

Thanks,
Princy.
