Hi ,
Check this

C#

 double sum = 0;
 foreach (Control c in this.Controls)
 {
     if (c is GroupBox)
     {
         foreach (Control item in c.Controls)
         {
             if (item is TextBox)
             {
                 sum += Convert.ToDouble(((TextBox)item).Text);
             }
         }
     }
 }

MessageBox.Show(sum.ToString());

Best Regards
M.Mitwalli
