    <asp:datagrid id="DataGrid1" runat="server" AllowPaging="True" 
    PageSize="5"></asp:datagrid>

    Private Sub Page_Load(ByVal sender As System.Object, _
    ByVal e As System.EventArgs) Handles MyBase.Load
        'Fill the Dataset
        Dim ds As New DataSet()
        ds.ReadXml(Server.MapPath(".") & "\..\Xml\PartList.xml")

        'Set the DataGrid's Source and bind it.
        DataGrid1.DataSource = ds
        If Not IsPostBack Then
            DataGrid1.DataBind()
        End If

        'Dispose Items
        ds.Dispose()
    End Sub

    'Implement the EventHandler for PageIndexChanged
    Private Sub ChangePage(ByVal source As Object, ByVal e As _
    System.Web.UI.WebControls.DataGridPageChangedEventArgs) _
