Question

I need some help showing me how to go about storing/saving changes made in a dataset back to the table(s) in the database. I'm using C# with windows forms on visual studio. Database is a local SQL Server.

I have managed to get the data to the data set but cannot save changes. the below is not saving to the database. ds is my dataset.

ds.AcceptChanges();

SqlDataAdapter dataAdaptor = new SqlDataAdapter();
dataAdaptor.Update(ds.Tables[0]);

Answer 1

 ....
 SqlDataAdapter dataAdaptor = new SqlDataAdapter();
 new SqlCommandBuilder(dataAdaptor);
 dataAdaptor.Update(ds.Tables[0]);
 ....

Answer 2

Have you set up all your Command properties for Select, Insert, Update, & Delete? These need to be configured before you can use the SqlDataAdaptor

Also see this link . The SqlCommandBuilder can automatically generate the command properties for you as long as you have your Select command set.
