How do I set the color and font on a RichEditBox?

You use the SelectionFont and SelectionColor properties. Make sure the control had focus. Then the following code will set the currently selected text to a red-bold-courier font. If no text is currently selected, then any new text typed (or inserted) will be red-bold-courier.

richTextBox1.Focus();
richTextBox1.SelectionColor = Color.Red;
richTextBox1.SelectionFont = new Font ("Courier", 10, FontStyle.Bold);
