Hi,
     I wished to do a sample text diff application using c#.Am facing the issue of changing the font of the diff chars

    Rich text box i wont be able to do as it supports rtf format so when a user is using rtf files to get differentiated it willdisplay or interpret it wrongly and in addition to that it supports max of 32 KB only.

    Web browser control is better and easy for my application but the issue comes when comparing the html code.
    it will parse the tags for display.

   How about using datagridview for this Is it advisable to use this.Putting every char in a cell and changing the
   background of the diff chars.

  Please advice me in this.

Thanks and Regards

What is the target application type? Web/Winform?

I don't see how using a web browser would be a problem. You simply need to make sure you HtmlEncode all the text before putting it to the browser.

Are you doing this to learn it or because you need a diff viewer? There are many programs out there already that have very good diff algorithms. I would be surprised if you couldn't find a .NET user control for this.
