var getdata = dm.Cloths.Where(w => w.Cloth_No == txtvalue).Select(w => new { w.Cloth_Name, w.Cloth_Type }).ToList();
           if (getdata.Any())
           {
               var sb = new StringBuilder();
               foreach(var item in getdata)
               {
                   sb.Append(item.Cloth_Name + " : " + item.Cloth_Type + "\n");
               }
               MessageBox.Show(sb.ToString()); 
           }
