ASP.NET

I'm using Visual Web Developer 2010 Express with SQL Server 2008, VB code behind.  Yesterday I had an issue with Gridview, today it is with Formview.

I'm exporting the contents of Formview to Excel and have a problem with the formatting.  One of my Formview cells contains component size data such as 0402, 0603, 0805 and displays correctly in Formview.  When that cell exports to Excel it displays as 402, 603 and 805.  Another cell contains a list of ECO numbers such as 4203,4204,4205 and exports as 420,342,044,205.  The page I'm exporting has two Formviews and Formview2 has similar potential issues.  What can I do to correct the export to Excel to show the data the way it appears in Formview?  The difference between Gridview and Formview is different enough that the solution for Gridview does not seem to apply to Formview.

Update: I should mention that inside Formview are numerous labels that actually contain the data I need formatted.  Is it possible to "format" the output of these labels?

vb code:
<pre lang="vb">    Protected Sub Button6_Click(sender As Object, e As EventArgs) Handles Button6.Click     'Export to Excel
        Dim lbl1 As Label = FormView1.FindControl("PART_NUMBERLabel")
        Response.ClearContent()
        Response.Buffer = True
        Response.AddHeader("content-disposition", String.Format("attachment; filename={0}.xls", lbl1.Text))
        Response.ContentType = "application/vnd.ms-excel"
        Dim stringWriter As New StringWriter()
        Dim stringWriter1 As New StringWriter()
        Dim htmlTextWriter As New HtmlTextWriter(stringWriter)
        Dim htmlTextWriter1 As New HtmlTextWriter(stringWriter1)
        FormView1.DataBind()
        FormView1.HeaderRow.Style.Add("background-color", "#FFFFFF")    'white; middle blue #3399FF
        For index As Integer = 0 To FormView1.HeaderRow.Cells.Count - 1
            FormView1.HeaderRow.Cells(index).Style.Add("background-color", "#969696")   'orange, was #d17250
        Next
        Dim index2 As Integer = 1
        FormView1.RenderControl(htmlTextWriter)
        Response.Write(stringWriter.ToString())
        If FormView2.DataItemCount <> 0 Then
            FormView2.DataBind()
            FormView2.HeaderRow.Style.Add("background-color", "#FFFFFF")    'white; middle blue #3399FF
            For index As Integer = 0 To FormView2.HeaderRow.Cells.Count - 1
                FormView2.HeaderRow.Cells(index).Style.Add("background-color", "#969696")   'orange, was #d17250
            Next
            index2 = 1
            FormView2.RenderControl(htmlTextWriter1)
            Response.Write(stringWriter1.ToString())
        End If
        Response.[End]()
    End Sub
