I have a datalist with custom paging thats inside a RADAjaxPanel in a usercontrol.  When I select pages in Firefox, the ajax functionality works fine (there is no full page postback), however, the same page in IE8 & Chrome generates a full page postback.  Anyone know why this should be ?  are there extra steps to take when using IE & Chrome ?
                                <telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server" Height="75px"        Width="75px">        <img alt="Loading..." src='<%= RadAjaxLoadingPanel.GetWebResourceUrl(Page, "Telerik.Web.UI.Skins.Default.Ajax.loading.gif") %>'            style="border: 0px;" />    </telerik:RadAjaxLoadingPanel>    <telerik:RadAjaxPanel ID="RadAjaxPanel1" runat="server" Width="100%"        EnablePageHeadUpdate="False" HorizontalAlign="NotSet"        LoadingPanelID="RadAjaxLoadingPanel1" >                        <div class="ArtistQueryItemrow">                               </div>             <div class="ArtistQueryItemrow">        <h1><asp:Literal ID="LiteralQueryMessage" runat="server" Visible="False"></asp:Literal></h1>    <asp:DataList ID="DataListBloggQuery" runat="server" RepeatLayout="Table"            onitemdatabound="DataListBloggQuery_ItemDataBound" Width="100%"            RepeatColumns="1">                 <ItemTemplate>            <div id="profile_listing">                   <div class="description">                                       <h1> <asp:Label ID="LabelBloggDate" runat="server"  AssociatedControlID="LiteralBlogg"></asp:Label></h1>                   <p><asp:Literal ID="LiteralBlogg" runat="server" ></asp:Literal></p>                                                       </div>                                                                                             </div>        </ItemTemplate>             </asp:DataList>    </div>        </telerik:RadAjaxPanel>
