How to navigate records from XML File?

[chdboy]

This code creates XML File

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim connetionString As String
        Dim connection As SqlConnection
        Dim adapter As SqlDataAdapter
        Dim ds As New DataSet
        Dim sql As String

        connetionString = "Data Source=.\SQLEXPRESS;AttachDbFilename=C:\Users\Danial\documents\visual studio 2010\Projects\ESI_PF_Payroll_V1\ESI_PF_Payroll_V1\Pay.mdf;Integrated Security=True;Connect Timeout=30;User Instance=True"
        connection = New SqlConnection(connetionString)
        sql = "select * from Acc"
        Try
            If IO.File.Exists("Testimage.xml") = False Then
                connection.Open()
                adapter = New SqlDataAdapter(sql, connection)
                adapter.Fill(ds)
                connection.Close()
                ds.WriteXml("Testimage.xml")
                MsgBox("File Created")
            Else
                MsgBox("File Already Exists")
            End If
        Catch ex As Exception
            MsgBox(ex.ToString)
        End Try
    End Sub

This code reads the file and send it's contents to text box(es)

 Dim xmlFile As XmlReader
        xmlFile = XmlReader.Create("Testimage.xml", New XmlReaderSettings())
        Dim ds As New DataSet
        While ds.ReadXml(xmlFile)
            Dim i As Integer
            For i = 0 To ds.Tables(0).Rows.Count - 1
                TextBox1.Text = (ds.Tables(0).Rows(i).Item(1))
                TextBox2.Text = (ds.Tables(0).Rows(i).Item(2))
                TextBox3.Text = (ds.Tables(0).Rows(i).Item(3))
                TextBox4.Text = (ds.Tables(0).Rows(i).Item(4))
                TextBox5.Text = (ds.Tables(0).Rows(i).Item(5))
                TextBox6.Text = (ds.Tables(0).Rows(i).Item(6))
                TextBox7.Text = (ds.Tables(0).Rows(i).Item(7))
                TextBox8.Text = (ds.Tables(0).Rows(i).Item(8))
                TextBox9.Text = (ds.Tables(0).Rows(i).Item(9))
            Next
        End While
End Sub

This code Navigates to the next record....and needs help

 Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
            Dim nav As XPathNavigator
            Dim docNav As XPathDocument
            docNav = New XPathDocument("Testimage.xml")
            nav = docNav.CreateNavigator
            nav.MoveToRoot()
            nav.MoveToNext()
            Do
                Dim i As Integer
                i = +1
            Loop While nav.MoveToNext
            'Pause.
            Console.ReadLine()
    		End Sub
