Hello all,
I have a strongly typed DataTable created with the VS2005/VS2008 DataSet designer.
The table has a Primary Key column that is a guid, which gets populated by SQL server. The problem is when I want add a row (or multiple rows) to my DataTable and then call the DataAdapter.Update method (passing in the DataTable). When DataAdapter.Update is called I get a SQL exception saying that I cannot insert NULL into the primary key column.
How do I tell the designer that this is an autogenerated column and I do not want to provide a value for new rows? I just want the value generated by SQL.
Am I missing something here, or is this a limitation of the DataSet designer?
I know how achieve this using LINQ to SQL, but unfortunatley I do not have it at my disposal for this project.
