compare data Between .aspx Two Pages in asp.net

I think what he is asking is how do you highlight a field when it is updated? In case you submit the changed data for approval at next level.

Please cut some slack to newbies, we were once new too. Asking the right questions will help them frame their next question the right way and save your time.

Your right, and personally I consider myself to be a newbie until now. :-)

That is why, I am forwarding him to a field that he might be able to get answers from, do you really believe, anyone here - instead of BillWoodruff - would provide entire solution to the problem. I tried doing the same, and I got ending up receiving a lot of downvotes as not keeping up with the usage terms.

Yes, I also guess that he is writing the same question, to check for the updates that both make, the things that second user makes an update for, and then do what so ever he might be able to. The good answer, for a newbie is not, here take this solution and use it, it actually is to forward him to a field that makes this possible. Which is, Source control! Like GitHub etc.

As per i understand, you want to track changes made from first step to nth step. If this is so, you have to store each steps data somewhere. It might be DB. Before moving from page,compare the stored data[It shows previous data] and the current steps data. List and LINQ will come handy in such case.
