Trapping backspace character key presses?

(I don't know how the face got into the previous post. It should be the number 8.) The ASCII character code for the backspace key is 8. Just add this line to the code: private void textBox1_KeyPress(object sender, System.Windows.Forms.KeyPressEventArgs e) { if (e.KeyChar != 8) if (char.IsNumber(e.KeyChar) == false) { e.Handled = true; } }

I replied to your post in the C# forum several days ago. Why didn't you acknowledge my response there? Did you get it to work? If so, where is your thanks? The ASCII character code for the backspace key is 8. Just add this line to the code: private void textBox1_KeyPress(object sender, System.Windows.Forms.KeyPressEventArgs e) { if (e.KeyChar != 8) if (char.IsNumber(e.KeyChar) == false) { e.Handled = true; } }

Keys.Back isn't the backspace key.
