Rich Text Box Color by line

[flyingeagle855]

I need to be able to change color by line as I add text to a RichTextBox here is the code I have so far.

private void Updatetext_error(string text)
        {
            Font fBold = new Font("Tahoma", 8, FontStyle.Bold);
            textBox1.SelectionStart = textBox1.Text.Length;
            textBox1.SelectionFont = fBold;
            textBox1.SelectionColor = Color.Red;
            textBox1.SelectedText = text;
            textBox1.SelectionStart = textBox1.Text.Length;
            textBox1.Text += "\r\n Contact your system administrator";
            textBox1.Select(textBox1.Text.Length - 1, textBox1.Text.Length - 1);
            textBox1.ScrollToCaret();

}

if I comment out

textBox1.Text += "\r\n Contact your system administrator";

then the text is red on the one line that was inserted using the

textBox1.SelectedText = text;

but if I try to add more text it makes all the text black. Any help would be great.

Never mind I found the issue I needed to add \r\n to

textBox1.SelectedText = text

So it should be

textBox1.SelectedText = text + "\r\n";

I think what happened was it was still trying to fomrat the selction since there was no new line, or somehting like that.
