check attached code. I just can not find why Response.Write(principalname.ToString()); has nothing to be shown.

<%@ Register src="PrincipalControl.ascx" tagname="PrincipalControl" tagprefix="uc1" %>

                string principalname = newprincipalinfo.principalname;
                Response.Write(principalname.ToString());
            }
        }

I doubt the value for principalname property is not set in your usercontrol...
Can you share the PrincipalControl UC control code?
Set breakpoints and see if the property value is getting set....before you are trying to access it.
