how to avoid displaying an error message

say you have a form called as "error". In this form You can have some custom message.

Now say you are geting error in sudmit  event handler. It will go to catch block and close the form and open the error form which you have created for custom message

private void btnSave_Click(object sender, System.EventArgs e)
{
    try
   {
     //put all your submit event handler code here
   
   }
    catch
   {
      // code to close this form and open the error form here
   }
   finally
   {
    
   }

}

As message says, you first must create an object using "new" keyword. Avoiding error message is not going to help.
