How to make text in a WinForms TextBox unselectable without disabling it?

Question

Is it possible to make the text in a TextBox unselectable without disabling the TextBox? It's a RichTextBox and I need it's formatting and selection features. I can't disable it because I want to handle MouseMove and MouseDown events.

So far I've thought about disabling the Text box and putting a panel on top of it which will delegate it's events to the textbox handlers, but I can't make the panel transparent so it hides the textbox.

Thanks.

Answer 1

What about dealing with the .Enter or .GotFocus events to clear any selection made?
You can see the opposite of what you wanted in Automatically select all text on focus in WinForms TextBox.

Answer 2

How about handling selection change event like this:

    private void richTextBox1_SelectionChanged(object sender, EventArgs e)
    {
        this.richTextBox1.SelectionStart = this.richTextBox1.Text.Length;
    }
