Remove complete text on BackSpace button press of keyboard in WinForms

Question

say i have a text box with readonly properties. It has text in the format [my string] i.e enclosed by square brackets.

I want if this textbox is focused and user press backbutton to delete this text, i know it wouldn't be possible as textbox is in readonly mode.

But still on pressing backbutton, Complete text will be delete not one char by one.

WinForms, WPF, ASP.NET? Always put in tags technology you are using — Sergey Berezovskiy, Apr 01 '13 at 06:26
Sounds like you are trying to re-invent a cue banner. Just use the [built-in support](http://stackoverflow.com/a/4902969/17034) for that. — Hans Passant, Apr 01 '13 at 11:27

Here is my solution..

I got it working my self

void txt_KeyPress(object sender, KeyPressEventArgs e)
    {
        if (e.KeyChar == '\b')
        {
            TextEdit textBox1 = sender as TextEdit;
            if (textBox1 != null)
            {
                textBox1.Text = "";
            }

        }
    }

Press Ctrl + A then press back button, it'll do the job,

TextBox tb = new TextBox();
tb.SelectAll();
