I am trying to replace an Excel spreadsheet and need to display rolling 12 month data with a gridview.  Here is some sample data.

tblProject                        
fldProjID,fldRegistration,fldStartDate,fldEndDate,fldHours
1,111ABC,25/07/2010,02/08/2010,16000
2,222ABC,09/08/2010,10/09/2010,24000
3,333ABC,02/09/2010,20/09/2010,24000
4,444ABC,20/10/2010,05/11/2010,32000

tblHours                        
fldHoursID,fldProjID,fldDate,fldHours      
1,1,01/07/2010,12000      
2,1,01/08/2010,4000      
3,2,01/08/2010,15750      
4,2,01/09/2010,8250      
5,3,01/09/2010,24000      
6,4,01/10/2010,22000      
7,4,01/11/2010,10000

I have attached a screenshot of how I would like the gridview to appear.  I have given two views and you can see how the months have rolled.

How do I get a gridview to show data in this manner?

you can use datatables. Load your data (from the 2 database tables) into 2 datatables. Process each of the Registrations (tblProject records) to generate a 3rd datatable which you will then display to the user.

Yes. With this approach, you would need to manually handle edits. I.E. when there is an edit, process it to map the data to the correct table.
