I am trying to save any changes to a datagridview control to a Microsoft Access database.  I am using the code show below to populate and set the update commands for the datatable.

Dim sSQL As String = "SELECT RecordNumber, LineNum, RecID, Pcs, Wgt FROM tblItems WHERE RecID = '" & sCrit & "' ORDER BY LineNum"

            Dim cn As New OleDbConnection(Global_Values.System_Database)
            daLineItems = New OleDbDataAdapter(sSQL, cn)
            dsLineItems = New DataSet
            dtLineItems = New DataTable

            If cn.State = ConnectionState.Closed Then
                cn.Open()
            End If

            'Insert Command
            Dim cmdInsert As New OleDbCommand("INSERT INTO tblItems (LineNum, RecID, Pcs, Wgt) VALUES (@LineNum, @RecID, @Pcs, @Wgt)", cn)
            daLineItems.InsertCommand = cmdInsert

            'Update Command
            Dim cmdUpdate As New OleDbCommand("UPDATE tblItems SET Line_Num = @LineNum, RecID = @RecID, Pcs = @Pcs, Wgt = @Wgt WHERE RecordNumber = @RecordNumber", cn)
            daItems.UpdateCommand = cmdUpdate

            daItems.Fill(dtLineItems)

            If dtItems.Rows.Count < 1 Then
                dtItems.Rows.Add()
            End If

            Me.DataGridView1.DataSource = dtItems
         

In the on-click event of a button i am using the following in an attempt save the changes back to the database:

          daItems.Update(dtItems)

When i click the save button I get the following error: No value given for one or more required parameters.

What am i doing wrong?

I looked to that but you didn't needed if you use in other way.
It's working and that is the most important :)
