Answer 1

Add some code to your update procedure to determine if it's being called:

1. Create a table called Logging (or any name of your choice) that has a column called Message (again, or any name of your choice)
2. Add a line to your UpdateNews procedure to INSERT INTO [dbo].[Logging] (Message) VALUES ('Procedure Called') . You could log the values of the parameters passed in, if you so wished.

By doing this you can determine if the stored procedure is actually being called or not. The other option is to use Sql Server Profiler to determine this. If you can determine that it is calling the stored procedure, then something is going wrong in there and by logging the parameters you can "hand call" it to find out why.

More likely is that the stored procedure is never being called, how are you telling the grid to persist the changes back out to the database? Looking at this tutorial , I would suggest that your updates are not triggering a "save".
