How to wrap Text in RichTextBox on rizing the form?

Question

Hi, I have a RichTextBox where I display the Rich Text, my problem is that on resizing the form the text in RichTextBox does not wrap, I have set wordwrap property of RichTextbox to true but still on resizing the form the text in Richtextbox is not wrapping. Any suggestions/ code would be helpful. Thanks Nitin
