Hello Yana
The attached web site is the same as mine, but in my web site i'm using this code :
<div class="anyClassa" dir="rtl" style="width: 100%">
<ul dir="rtl">
<!--#include virtual="generated_files/books_BestSellers.txt"-->
<li>
<img height="183" width="165" alt="end" src="doublearrows.png" /></li>
</ul>
</div>
The error is in using "anyClassa" from style.css , because RadScriptManager in Masterpage, knowing that I used
ScriptManagerProxy in content page.
Thanks
Best Regards
