clear textbox c#

  • 772

**Hello, I'm trying to clean a TextBoxby pressing the ctrl+delete keys but I don't get the option KeyCode, does anyone know what I'm doing wrong?

    private void txtUsuario_KeyPress(object sender, KeyPressEventArgs e)
    {
        if (e.KeyCode == Keys.Delete && e.Control)
        {
            txtUsuario.Text = "";
        }
    }

UPDATE:

I got what I was looking for as follows:

    private void txtUsuario_KeyDown(object sender, KeyEventArgs e)
    {
        if (e.KeyCode == Keys.Back && e.Control)
        {
            txtUsuario.Text = "";
        }
    }

But, this form adds a strange character:

How is it solved?

    You have to put two conditions (pressed delete and pressed Control) to evaluate the KeyPress

        private void txtUsuario_KeyPress(object sender, System.Windows.Forms.KeyPressEventArgs e)
    {
        if (e.KeyCode == Keys.Delete && e.Control)
        {
            txtUsuario.Text = "";
            e.Handled = true;
        }
    }
