Solution 2

for each text box write a TextChanged Event handler on that write below mentioned code

C#

private void tbx1_TextChanged(object sender, EventArgs e)
{
   try
   {
      tbx_TotalSum.Text=tbx1.Text+ .....+tbxn.Text;
   }
   catch
   {
      throw;
   }
}

Solution 1

Update the total textbox value (that is perform the sum) in the TextChanged[^] event handler of any of the other textboxes (you may associate the same event handler to all such textboxes).

try
{
decimal sum = 0;

sum = Convert.ToDecimal(textbox1.Text) + Convert.ToDecimal(textbox2.Text) +
Convert.ToDecimal(textbox3.Text);

txttotal.Text = sum.ToString();
}
catch(Exception ex)
{
MessageBox.Show(ex.Message,"Error");
}
