There is no inbuilt mechanism other than "undo" - which may remove more than just the last character.
You may be able to do something on your own though.
I would create my own control, based on a TextBox and add a Stack<string> to it as a private member.
Handle the TextChanged event and push the new value on the stack.
When you want to undo the last character, pop off the top value, discard it. Pop off the next value, and set the textbox text to that. (This will cause a TextChanged event, which will put it right back on again)

Clearly, you will need to check for empty, and so forth, but that's the way I'd do it.

Solution 1

Have you tried this?

C#

textBox1.Text = textBox1.Text.SubString(0, textBox1.Text.Lenght - 1);
