Undo Redo with Entity Framework

Question

I'm converting a .net program's db access from old school sql to EntityFramework currently it has an 'undo redo' feature by holding the sql scripts in a container for later use.

Is there an easy way to implement undo redo mechanism with entity framework?

Thank you very much Rony

--EDIT-- I think I didn't explain myself properly.. I need to keep all history to my SQL SELECT queries. In the previous app I kept such list of all my queries and this allowed me to perform any number of undo / redo steps.

You can implement such behavior taking advantage of DbContext's Property Values. This ADO.NET team blog article explains it in good detail: Using DbContext in EF 4.1 Part 5: Working with Property Values
