Hello Banshi,

If you are using AJAX or PDF export in medium trust please examine the following links:
Using RadAjax in Medium Trust
PDF export

If you are already in full trust, you can check this link:
http://dbvt.com/blog/post/AspNetHostingPermission-Security-Exception-Fix-with-Ajax-in-IIS7.aspx

Other than this, I suggest you try a newer version of RadControls for ASP.NET AJAX.
