Changes highlight in asp.net (like beyond compare) : Text or HTML comparison

Question

Hi, I need to highlight changes(diff) between 2 database text fields in a asp.net application.

I'm used to "beyond compare" text compare, so the Ideal solution will do something like it, but if it just highlight the differences, that would be OK.

The content is HTML, so if it could compare the HTML rendered text, it would be even better.

So, i need a link or a control (free if possible) to do that job.

thanks

I think what you're asking is pretty complex. I can't find any control out there that will do this, but i did find this: Difference Algorithm for C#

It doesn't give you exactly what you need, but it's a good place to start.
