Hello
To update a dataset i created a method (see below)
My question is, how to return the created Primary ID that is created on the
server auto incremential. Is there anyway to place that value into the
correct inserted row?
Kind regards

#region Method 'Save'

bool IsValid = true;
if (Datasource != null)

if (dsChanges != null)
{
OleDbConnection con = new OleDbConnection(_ConnectionString);
try
{
con.Open();
}
catch (Exception ex)
{
ErrorLogger.WriteToErrorLog(ex.Message, ex.StackTrace,

IsValid = false;
