Hi,
I am not sure if I understand your request correctly, because IsGlobalAdministrator checkbox is disabled for users who are not global administrators by default. You can take a look into
~\CMSSiteManager\Administration\Users\User_Edit_General.aspx.cs file, where you can see following code in
Page_Load method:
CheckBoxLabelIsGlobalAdministrator.Enabled = CMSContext.CurrentUser.IsGlobalAdministrator;As a result, only global administrators are able to use enabled IsGlobalAdministrator checkbox.
So could you please describe in more detail what are you trying to achieve?
Moreover, which version of Kentico
CMS are you using?
Best regards,
Michal Legen
