Hi,

May be something like this:

  // DataSet Orders = new DataSet();  // What ever DataSet that it is ...
  ...

  bool isAnyRec = false;
  foreach (DataTable myDT in Orders.Tables)
      if (myDT.Rows.Count() > 0)
      {
          isAnyRec = true;
          break;
      }

  ...
  if( !  isAnyRec )
      Orders.Tables["Details"].Rows.Add( myDataRow );

> I want to be able to have my Add button to add a record into the Orders DS if I don't have a record there and then add record to the Details table.

> My question is - how can I check if I already have records in Orders DS or not?
