If you got everything correct, you will just see confirmation of what was performed by the wizard (see Figure 11). I usually type -1 for my NullValue on System.Int32 datatype columns. Insults are not welcome. System.Data.DataRowView viewRow = (System.Data.DataRowView)view.Rows[e.RowIndex].DataBoundItem; myDataSet.ProductRow row = (myDataSet.ProductRow)viewRow.Row; if (row.NullableCommentDate == null) row.NullableCommentDate = DateTime.Now; The advantage of doing it this way is that the DataSet Designer won't overwrite changes made

Since you can set the value in the properties for string types only, those are not a problem. First off, you should consider using stored procedures as a layer of decoupling between your actual data tier schema and your application. Visual Studio Dataset Designer However, you still usually have to write all the data access methods by hand for the ad-hoc queries that service large parts of your application.
