Need help with Datagrid Sorting

I am looking for some help in fixing a datagrid problem. I am using the following code to capture a double click and open our Order Entry form:

'Add Textbox Double Click Hander
AddHandler dgcsOrderID.TextBox.DoubleClick, New EventHandler(AddressOf TextBoxDoubleClickHandler)

'Opens Order Form with Double Clicked Order ID
Private Sub TextBoxDoubleClickHandler(ByVal sender As Object, ByVal e As EventArgs)
        Dim drID As DataRow = objdsOrders.qryLIST_Orders.Rows(dgOrders.CurrentCell.RowNumber)
        Dim intOrderID As Integer = drID.Item("OrderID")

        If intdblclickcount = 0 Then
            OpenDisplay(intOrderID)
            intdblclickcount = 1
        End If
End Sub


This works fine when the form is first opened. However, when I sort on any column header, the data sorts, but apparently, the underlying data [objdsOrder.qryLIST_Orders.Rows(dgOrders.CurrentCell.RowNumber)] does not. When I double click the order ID, it opens the original unsorted value of that row, not the display data. For example:

Before I sort the data:
Order     Customer
00001     Bob
00002     Steve
00003     Alan

Clicking on row one opens Bob's order - this is fine.

After I sort the data:
Order     Customer
00003     Alan
00001     Bob
00002     Steve

Clicking on row one still opens Bob's order - this is not fine.

I need a way to retrieve the sorted data, and points will be awarded to code that accomplishes that. TIA.
