If its a web application I will suggest to go for JavaScript or JQuery. We can avoid unnecessary round trips..

It would be preferable IMO to handle the textbox's Leave event so that you can be sure that the user has finished typing but if you want to do it dynamically try: private void txt_availed_TextChanged(object sender EventArgs e) { int availed; if (int.TryParse(txt_availed.Text out availed)) { int eligibility if (int.TryParse(txt_eligibility.Text out eligibility)) { txt.Balance.Text = (eligibility - availed).ToString(); } } }
