You should not be passing data object classes like this between pages. If you need to access the data in separate pages you should use an ID or other types of parameters to access the data on each page as necessary. You can use query strings or session variables to share information.

Nischalke is right, rethink this strategy. if you gave an overall concept of what you were trying to do then we could think up a better strategy.

Since you are going to repeat your question, I'll repeat my answer. You don't pass such objects between pages.

If your data access code is centralized, say in a separate class, or library, then all you need to share between the pages are the criteria to access it. For instance an ID.

The question is not too clear. But you can use stuff like Session...

Good in theory but it misses the point that such objects should not be stored in session state.
