Hello Amit,

More information about how to avoid this error is available in the following forum post  :
http://www.telerik.com/community/forums/aspnet-ajax/general-discussions/ajax-2-9-q2-release-giving-me-gray-hair.aspx

Additionally, to avoid the parser error you should put interval before AllowPaging property:

<telerik:RadAjaxPanel ID="RadAjaxPanel1" runat="server">
    <telerik:RadGrid ID="RadGrid1" runat="server" AllowFilteringByColumn="True" OnNeedDataSource="RadGrid1_NeedDataSource"
        AllowPaging="True" AllowSorting="True" GridLines="None" Skin="Office2007">
        <MasterTableView>
            <RowIndicatorColumn>
                <HeaderStyle Width="20px" />
            </RowIndicatorColumn>
            <ExpandCollapseColumn>
                <HeaderStyle Width="20px" />
            </ExpandCollapseColumn>
        </MasterTableView>
        <ClientSettings AllowColumnsReorder="True" ReorderColumnsOnClient="True">
        </ClientSettings>
    </telerik:RadGrid>
</telerik:RadAjaxPanel>

I hope this helps.
