PageSize

[Issac]

When setting PageSize in code behind, pager will not navigate past page 1.

    Dim dataPager As RadDataPager = DirectCast(lstProduct.FindControl("RadPager1"), RadDataPager)
    dataPager.PageSize = 36

Tried using the Page Size Field, I can navigate past page 1, but the page size does not work.
Also, once I use AllowSEOPaging="true" Visual studio shows "There was an error rendering the control. Request is not available in the context" 

<telerik:RadListView ID="lstProduct" Width="80%" EnableEmbeddedSkins="false" AllowPaging="True"
    runat="server" ItemPlaceholderID="ProductsHolder">
    <LayoutTemplate>
