>I have a totals item in the footertext of a DataGrid and the totals is always one refresh behind. I have pulled the code to do the refreshing out into a sub and I have tried calling that sub in the page load regardless of postback status, At the end of the databind process, and both.

The answer, I have discovered, is the OnItemDataBound attribute of the DataGrid tag. 1pt to 4GuysFromRolla for inadvertently steering me to the answer. :)
The following code works great.
'Be sure to add OnItemDataBound="UpdateCartSubTotal" to the datagrid tag on the HTML side
'eg- < DataGrid id="grdCart" runat="server" ShowFooter="True" OnItemDataBound="UpdateCartSubTotal">

        Dim CartSum As Double = 0.0
        Sub UpdateCartSubTotal(ByVal sender As Object, _
                                         ByVal e As DataGridItemEventArgs)
            'Item or AlternatingItem ?
            If e.Item.ItemType = ListItemType.Item Or _
                  e.Item.ItemType = ListItemType.AlternatingItem Then
                'Snip out the ViewCount
                Dim viewCount As Double = _
                     Convert.ToDouble(DataBinder.Eval(e.Item.DataItem, "Retail"))
                CartSum += viewCount
            ElseIf e.Item.ItemType = ListItemType.Footer Then
                e.Item.Cells(3).Text = _
                    "<P align='right'>Subtotal: </P>"
                e.Item.Cells(4).Text = _ 
                    "<P align='right'>" & Format(CartSum, "0.00") & "</P>"
            End If
        End Sub
