Problema con combo

quiero que muestre un folio, el codigo es el siguiente:

Imports System.Data

Imports System.Data.SqlClient

Imports System.IO

Imports System.Xml

Imports System.Text

Imports System.Globalization

Imports Microsoft.WindowsCE.Forms

Private dvFolios As System.Data.DataView

Private data As System.Data.DataSet

Private Sub loadXMLData()

Try

data = New DataSet("ds")

Dim fs As New FileStream("\My Documents\verinspda.xml", FileMode.Open)

Dim xr As New XmlTextReader(fs)

data.ReadXml("\My Documents\verinspda.xml")

Me.combobox_folios.DataSource = data.Tables(0)



Me.combobox_folios.DisplayMember = "folio"

Catch e As System.IO.FileNotFoundException

MessageBox.Show("El archivo XML no es encontrado. Por favor seleccione un
nombre diferente.")

Catch e As XmlException

End Try

End Sub

Private Sub ComboBox_Folios_SelectedIndexChanged(ByVal sender As
System.Object, ByVal e As System.EventArgs) Handles
combobox_folios.SelectedIndexChanged

If combobox_folios.SelectedIndex >= 0 Then

Dim strRF As String

Dim row As DataRowView > CType(combobox_folios.Items(combobox_folios.SelectedIndex), DataRowView)

Me.combobox_folios.DisplayMember = "folio"

Me.TextBox1.Text = row("tipo")

Me.TextBox2.Text = row("Folio")

End If

End Sub

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles MyBase.Load
