DataAdapter.Update() does not Update the Database

Question

I\'m sure there is an extremely simple reason that this one line isn\'t working, but it has evaded for the past week, so I\'m hoping someone else will notice my fault.

Answer 1

In order to update the data on the database your SqlDataAdapter need to have its InsertCommand, UpdateCommand, DeleteCommand properties set. The SqlCommandBuilder instance that you've created has these commands but you need to set them to your SqlDataAdapter.

In other worlds: Somewhere between

 SqlCommandBuilder cb;
 cb = new SqlCommandBuilder(dataAdapt);

and

 dataAdapt.Update(dataRecipe, "CookBookRecipes");

you need to

dataAdapt.DeleteCommand = cb.GetDeleteCommand(true);
dataAdapt.UpdateCommand = cb.GetUpdateCommand(true);
dataAdapt.InsertCommand = cb.GetInsertCommand(true);
