I have a people control in which I have populated current user name.So I have set its default value as "Current User" from insert preference in nintex form. And it shows current logged in username. Now I have to disable this control as none can change it. I have set its control mode as "display" from control setting. but When the page posts back because of cascading drop down, the values goes from control. How can I set it as disable so that its value remains in control.
