  Hi,
  

  
  I develop an application that have 20 windows forms with many TextBoxes.
  All TextBoxes have the same validation...
  I write in all classes the same validation like that:
  

  
  

  
  

  
  [CODE]        
         //if the user press a key down at txtDisplacement we check which one was pressed down
         #region KeyDownInTxtDisplacement code
         private void KeyDownInTxtDisplacement(object sender, System.Windows.Forms.KeyEventArgs e)
         {
             CheckWhichKeyDown(e);
         }
         #endregion
  

  
  

  
  

  
         //if the user press a key down at txtModel we check which one was pressed down
         #region KeyDownInTxtModel code
         private void KeyDownInTxtModel(object sender, System.Windows.Forms.KeyEventArgs e)
         {
             CheckWhichKeyDown(e);
         }
         #endregion
  

  
  

  
  

  
         //we check which key is pressed
         //if key Enter or Return or Tab is pressed
         //we go throw DoWhenOneTextBoxIsMarkedRed()
         #region CheckWhichKeyDown code
         private void CheckWhichKeyDown(System.Windows.Forms.KeyEventArgs e)
         {
             if(e.KeyCode==Keys.Enter || e.KeyCode==Keys.Return || e.KeyCode==Keys.Tab)
             {
                 ValidateThis();
             }        
         }
         #endregion
  

  
  

  
  

  
         //when special key is press we enable the button
         #region ValidateThis code
         private void ValidateThis()
         {
             cmdAddToDataBase.Enabled = true;
         }
         #endregion
  [/CODE]
  

  
  

  
  

  
  

  
  CheckWhichKeyDown and ValidateThis should be in one validation class.
  How I can write a validation class that validate ALL TextBoxes from all classes.
  Any ideas?
  Or do you know some sample validation classes available on www?
