How to pass a set of data across projects to a GridView in ASP.NET 2.0?

I am using the new Visual Studio 2005 and ASP.NET 2.0 (C #) to create a Web application level-3 with the business logic in the middle tier (and Access database) into a DLL file created in a separate project in VS2005 on the website. How I can transfer data back and forth between the DLL and the web site to fill a GridView component and is still able to make the update rule, Insert, delete the data? All examples in books and on the web assume that data objects were created in the same project as the website (design and level 2 poor practice). I can create and complete a standard data set, and then using a GridView DataSource / DataBind. This shows the data, but when I click Clear the Edit Constructed, nothing happens (screen, just forward, no errors). I guess I should add the code in the update / Controllers elimination event, but what? And how I can send the modified data back to update the database? Books, websites, examples? Help!

You do not have to create a custom update update, and delete the button when you are working with a dataset. create a template column and updating and buttons to eliminate there. Where GridView databinding sure to specify the grid line to the attribute control buttons. In this way, you know the line it clicks. Then, when you click update or delete if the database update. make sure your data set before displaying more DataBind the grid so that changes reflected on the screen.
