Radgrid Viewstate Issue when Paging

[Masande Dyasi]

Hi

I use a radgrid on a search page to list search results in a paged manner. If a result-set returns more that 1 page of data and a user navigates to the last page all subsequent attempts to search result in no data displayed on the grid. This is despite that fact that on the quick-watch window the data is clearly there. The behaviour is the same regardless of whether simple or advanced data-binding is used. I have also tried to disable Viewstate and ViewstateMode to resolve this issue to no avail. Please see the grid client code below.

<telerik:RadGrid id="gvSearchDetails" runat="server" autogeneratecolumns="false" 
                        allowfilteringbycolumn="true" allowpaging="true" allowsorting="true"  ViewStateMode="Disabled"
                        allowmultirowselection="false" PageSize="10" onneeddatasource="gvSearchDetails_NeedDataSource" onitemdatabound="gvSearchDetails_ItemDataBound" EnableViewState="False">
                    <MasterTableView DataKeyNames="ReferenceNumber">
                        <Columns>
                            <telerik:GridTemplateColumn DataField="ReferenceNumber" headertext="Ref #" headerstyle-font-bold="true" UniqueName="clSensAnnouncementReference">
                                <ItemTemplate>
                                    <asp:LinkButton id="lnkReferenceNumber" runat="server" readonly="false" guid='<%# Eval("AnnouncementID") %>' text='<%# Eval("ReferenceNumber") %>' OnClick="lnkReferenceNumber_Click"></asp:LinkButton>
                                </ItemTemplate>
