Sys.WebForms.PageRequestManagerTimeoutException problem

[finesoul]

on the page we add parameter AsyncPostBackTimeout to the ScriptManager
<asp:ScriptManager ID="ScriptManager1" runat="server" AsyncPostBackTimeout ="360000"/>
and in web.config we add additional option
<httpRuntime maxRequestLength="1024000" executionTimeout="999999"/>
</system.web>
</configuration>
