Autofit WinForms RichTextBox to its contents

Question

Does anybody know how can I dynamically resize a RichTextBox control to its contents?

Answer 1

I guess I am far too late but take a look at this

It's just two code lines:

private void rtb_ContentsResized(object sender, ContentsResizedEventArgs e)
{
    ((RichTextBox)sender).Height = e.NewRectangle.Height + 5;
}
