select all text in a textarea with CTRL+A

Question

In a winforms application, is it possible to select all text using CTRL+A?

Answer 1

Just write the KeyDown event handler for the text box:

    private void textBox1_KeyDown(object sender, KeyEventArgs e) {
        if (e.KeyData == (Keys.Control | Keys.A)) {
            textBox1.SelectAll();
            e.Handled = e.SuppressKeyPress = true;
        }
    }

UPDATE: starting with .NET 4.6.1, TextBox now has this shortcut keystroke pre-defined.

Answer 2

put event onkeypress and use SelectAll Method

Answer 3

Note that Ctrl-A to select-all works out-of-the-box (by default) in the RichTextBox control.
