RichTextBox text highlighting

In my form there's a UserControl that has multiple RichTextBox's and TexBox's.

While tabbing into TextBox's via keyboard, as soon as a TextBox get focus the entire text in it is highlighted in a blue background. Looks like a default behavior.

Now while tabbing into RichTextBox's via keyboard, as soon as a RichTextBox get's focus, the cursor is shown inside the box and no text is highlighted with blue background. Probably a default behavior.

How can i make the RichTextBox also to highlight the text in blue background whenit get's focus via keyboard tabbing?

If you are looking to change the background color rather than select the text you can use something like the following. 

    private void richTextBox1_Enter(object sender, EventArgs e)
    {
        richTextBox1.BackColor = Color.LightBlue;
    }
    private void richTextBox1_Leave(object sender, EventArgs e)
    {
        richTextBox1.BackColor = Color.White;
    }

Just use the Enter event and call the SelectAll() method.

private void richTextBox1_Enter(object sender, EventArgs e)
{
    richTextBox1.SelectAll();
}
