Itis bretty easy just override the OnTextChanged event and check the new char if it is a number or uppercase,you can know about numbers by putting them in an array,or just trying double.TryParse() function,in a try-catch block;

Capture the KeyPress Event of TextBox The following is for numeric. Add condition for Upper Case. private void TextBoxInceptionANAKeyPress(object sender, System.Windows.Forms.KeyPressEventArgs e) { try { //Handle only if the value being entered is NUMERIC if (e.KeyChar >= (char) 48 && e.KeyChar <= (char) 57 ) { e.Handled = false; } else { //Sound beep MutualFundHelper.SoundBeep(); e.Handled = true; } } catch (Exception exception) { MessageBox.Show(exception.Message); } }
