I am having problem with the following code. Delete function does not work (throws scalar variable error). Update function does not work … it does not throw any error, but it simply does not make changes to the database.
If I make exact DetailsView, everything works OK. Where is the problem?

Do you mean it doesn’t work with a gridview but does work with a DetailsView? If so, then you need to set DataKeyNames for the gridview.
You can look at this for further details: http://fabdata.wordpress.com/2007/03/23/must-declare-the-scalar-variable-id/
