Few companies that installed computers to reduce the employment of clerks have realized their expectations.... They now need more and more expensive clerks even though they call them "Developers" or "Programmers."

hi
i have same problem
the below link helped you:

http://stackoverflow.com/questions/290121/asp-net-ajax-error-sys-webforms-pagerequestmanagerparsererrorexception[^]

in this post describe about reason of this problem and solutions

in brief, if you have update panel tag modify your tag like this:

ASP.NET

<asp:updatepanel ID="updatepanel1" runat="server">
       <Triggers>
           <asp:PostBackTrigger ControlID="button1" />
       </Triggers>
       <ContentTemplate>

       </ContentTemplate>
   </asp:updatepanel>

instead of button1 write your object name
