Datapager always marks page 1

I'm facing a problem with two Datapagers associated with a Listview. This is my page:

<asp:DataPager ID="PagerTop" runat="server" PagedControlID="pp" QueryStringField="page" PageSize="30"></asp:DataPager>

<asp:ListView ID="pp" runat="server" ItemPlaceholderID="holder" EnableViewState="true" OnPagePropertiesChanging="PagePropertiesChanging">
...
</asp:ListView>

<asp:DataPager ID="PagerBottom" runat="server" PagedControlID="pp" QueryStringField="page" PageSize="30"></asp:DataPager>

and the code behind is as follows

Private Sub Page_PreRender(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.PreRender
    Dim MyData As List(Of Product)
    MyData = ResultsManager.GetResults()
    pp.DataSource = MyData
    pp.DataBind()
End Sub

Private Sub PagePropertiesChanging(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.PagePropertiesChangingEventArgs)
    PagerTop.SetPageProperties(e.StartRowIndex, e.MaximumRows, False)
    PagerBottom.SetPageProperties(e.StartRowIndex, e.MaximumRows, False)
    pp.DataBind()
End Sub

When I change the page, the listview is updated and shows the results corresponding with the indicated page, and PagerTop shows the selected page. That's how they are supposed to work. But PagerBottom is stucked on page 1 and never changes!

It doesn't matter which pager I click, PagerTop always works and PagerBottom always stays at page 1.

I'm running out of brilliant ideas... what can be wrong here?

Solution

  • a very good example is given here http://www.c-sharpcorner.com/uploadfile/nipuntomar/datapager-in-Asp-Net-3-5/ just place another data pager with different id without any change. i have tried and worked fine for me.
