Programmatically databind listview while using datapager - asp.net

Question

I have a listview and two data pagers. My listview is hooked up to a data source whose data is ordered randomly. ORDER BY NEWID()
As you can imagine, each time I select a page or click next/prev page all the data is randomized making the datapager quite useless.
I figured I could set the datasource when the page is not posted back and then programmatically set the datasource to the listview but now when selecting a page or clicking the next/prev buttons, the page just simply doesn't change..
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Not IsPostBack Then
Dim dv As DataView = sdsMembres.Select(DataSourceSelectArguments.Empty)
lvListMembres.DataSource = dv
lvListMembres.DataBind()
DataPager2.PagedControlID = "lvListMembres"
DataPager3.PagedControlID = "lvListMembres"
DataPager2.DataBind()
DataPager3.DataBind()
End If
End Sub
What am I missing / is there a better way to do this. The order by MUST be random and I MUST have the data pagers separate from the listview.
Thank you!

Take the code between the If statement and place it in a separate function.
Add a method of storing the data, in this particular case I'll store it as a DataTable in a session.
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Not IsPostBack Then
' Clear datatable from session
Session("CourtierList_dt") = Nothing
' Set datasource to listview and save in a session variable
SetCourtierList()
End If
End Sub
Protected Sub SetCourtierList()
Dim dt As DataTable
If Session("CourtierList_dt") Is Nothing Then
Dim dv As DataView = sdsMembres.Select(DataSourceSelectArguments.Empty)
Session("CourtierList_dt") = dv.ToTable
End If
dt = Session("CourtierList_dt")
lvListMembres.DataSource = dt
lvListMembres.DataBind()
DataPager2.PagedControlID = "lvListMembres"
DataPager3.PagedControlID = "lvListMembres"
DataPager2.DataBind()
DataPager3.DataBind()
End Sub
Also, make sure to add the PagePropertiesChanging event to the listview
Protected Sub lvListMembres_PagePropertiesChanging(sender As Object, e As System.Web.UI.WebControls.PagePropertiesChangingEventArgs) Handles lvListMembres.PagePropertiesChanging
DataPager2.SetPageProperties(e.StartRowIndex, e.MaximumRows, False)
DataPager3.SetPageProperties(e.StartRowIndex, e.MaximumRows, False)
SetCourtierList()
End Sub
And there you have it, hope this is helpful for someone.
