Answer 1

You can use KeyDown event to count the keys pressed, so it'll be something like the code below.

int count = 0;
private void richTextBox1_KeyDown(object sender, KeyEventArgs e)
{
    if (e.KeyCode == Keys.BackSpace)
        count++;
    else if (e.KeyCode == Keys.Enter)
        //Show Message.
}
