Now i can save and retrieve the datagridview from/to xml

Private Sub LoadSuppliers()<br />

        m_CommandSupplier = New SqlCommand<br />
        m_CommandSupplier.CommandText = "Select SupplierId, SupplierName from Suppliers"<br />
        <br />
        Try<br />
            m_DaSupplier = New SqlDataAdapter<br />
            m_DaSupplier.SelectCommand = m_CommandSupplier<br />
<br />
            // connection has already been created in seprate Sub-Routine            m_DaSupplier.SelectCommand.Connection = m_ConnectionSupplier<br />
<br />
            m_DsSupplier = New DataSet()<br />
            m_DaSupplier.Fill(m_DsSupplier)<br />
<br />
        Catch ex As Exception<br />
<br />
            MsgBox(ex.ToString, MsgBoxStyle.Critical, " Get Suppliers")<br />
<br />
        End Try<br />
<br />
        m_DsSupplier.Tables(0).TableName = "Suppliers"<br />
<br />
1 - it's DisplayMember to the field that's supplying the Text the user gets to see in the Combo and set the ValueMember property to the field that's supplying the ID's for those text items.<br />
<br />
2 - create a new Binding object and add it to the DataBindings property of the ComboBox<br />
<br />
Both these task are accomplished in the following code, SupplierNAme is set as Display MEmber , while the SupplierID is set a value member.<br />
<br />
        With SupplierIDComboBox<br />
            .DataSource = mDsSupplier.Tables("Suppliers")<br />
            .DisplayMember = "SupplierName"<br />
            .ValueMember = "SupplierId"<br />
            .DataBindings.Clear()<br />
            .DataBindings.Add("SelectedValue", PurchaseOrderDetailsDataSet.PurchaseOrders, "SupplierId")<br />
<br />
        End With<br />
<br />
<br />
    End Sub

Now when i run the program, the value for PurchaseOrder and PurchaseOrderDetails tables in both Details and datagrid goes fine.

But when i click 'MOVE NEXT RECORD' button from BINDING NAVIGATOR. All the values in Textboxes and DATAGRIDVIEW changes accurately. But the values in comboboxes like SUPPLIER ID does not change. and it stick to the value that was loaded with FIRST RECORD. What should i do?
