InfoPath Dev

I'm trying to add a new line in a RichTextBox using the following: execSummary = execSummary.Replace(";", System.Environment.NewLine); //execSummary is a string I'm trying to replace every semi-column with a new line when the user presses a button, but what happens is that the semi column will only disappear and have a white space instead. Is there anyway I can add a new line using c#, or can I do it without coding? What is weird, when I show the modified text in a message box it is showing as it should be! But not when I check the rich text box .... o.O Thank you

Open the XML in a text editor and look at some rich text with line breaks. :) It is XHTML. You'll need to replace your ";" with "<br />" instead I think.

EDITED to add the "<br />" back in, since the browser ate it. 

I tried that, but the form is typing
instead of a new line.. I can add them manually but it is not working that way... weird

I think you have to get the inner xml of the node - then do your replace, then set the inner xml of the node....

Do you have any example that can help me out ?

It says InfoPath 2007, but will be pretty much the same for 2010 and 2013. 

Is there a way to get new line in rich text box without using C#? I need to work in InfoPath, would like the rule to work when a button is clicked. I tried XML but it didn't work. Do you have any smaple that would work just in InfoPath maybe from reading new line command from other source?
