            foreach (string s in values)
            {
               if(SPUtility.IsLoginValid(SPContext.Current.Site,s))
               {

                    userList.Add(user);
               }
               else

                    SPGroup oGroup = SPContext.Current.Web.SiteGroups[s];
                   groupList.Add(oGroup);

                grdUser.DataSource = userList;
                grdUser.DataBind();
            }
