  myDataTable.Connection = myConnection;

  myDataTable.SelectCommand.CommandText = "SELECT * FROM Test.Dept";

  myDataTable.RowFetched += new EventHandler(myDataTable_RowFetched);
  myDataTable.FetchFinished += new EventHandler(myDataTable_FetchFinished);
  myDataTable.Open();
}

static void myDataTable_RowFetched(object sender, EventArgs e) {

  Console.Write(string.Format("{0} rows are fetched", ((DbDataTable)sender).RecordCount));
}

static void myDataTable_FetchFinished(object sender, EventArgs e) {
  
  Console.Write("All records are fetched");
}

Visual Basic

Private Shared Sub UseDataTable(ByVal myDataTable As DbDataTable, ByVal myConnection As DbConnection)
  myDataTable.Connection = myConnection
  myDataTable.SelectCommand = myConnection.CreateCommand
  myDataTable.SelectCommand.CommandText = "SELECT * FROM Test.Dept"
  AddHandler myDataTable.RowFetched, New EventHandler(AddressOf Form1.myDataTable_RowFetched)
  AddHandler myDataTable.FetchFinished, New EventHandler(AddressOf Form1.myDataTable_FetchFinished)
  myDataTable.Open()
End Sub

Private Shared Sub myDataTable_RowFetched(ByVal sender As Object, ByVal e As EventArgs)
  Console.Write(String.Format("{0} rows are fetched", DirectCast(sender, DbDataTable).RecordCount))
