I am working on a page having Rad List View and RadDataPager. I am using Rad Ajax manager and Rad Ajax Loading Panel to display loading image when navigating between pages.
Everything is functioning well until I am setting the AllowSEOPaging="true" in the Data Pager. When I set AllowSEOPaging="true" and SEOPagingQueryPageKey="Page" the data pager display appearance is wrong and the loading image is not appearing.
Whenever there is a post back IsPostBack Value is always false and this is a weird thing.

 <form id="form1" runat="server">

Hello Elais,

Actually this is expected behavior when SEOPaging is enabled. As you may know this option is designed to work for Web crawler and it will be enabled automatically if such is accessing the page. Thus the pager it will generate links instead buttons which will make GET instead POST requests.
