Try to use the Session, as described in the ASP.NET Session State Overview MSDN topic.

Just store your data in your pages's Session property (something like: Session["MyEnteryName"] = myEntry;) and, read it in the next cycle (something like: myEntry = Session["MyEnteryName"];).

You need to use one of the state management techniques to implement it:
MSDN: ASP.NET State Management Overview[^]
State management in ASP.NET - 1[^]
ASP.Net State Management Techniques - 2[^]
