disable the tab in ax 2012 using Roles

Hi all,

i want to disable the tab in ax 2012 using Roles.The screen shot

attach below

What is the screenshot supposed to show?
Anyway, if user don’t have permissions to see any controls on a tab, the tab won’t be displayed at all.

You can also restrict access to specific control by using NeededPermission property of the control.

if we give “NoAccess” the particular button wont show…if any possible to make disable ??
