ASP.Net 4.5 + Report Viewer 11.0 having blank report

Recently, I did a ASP.Net application. It is developed by VS 2012. There is a page showing a report by using Report Viewer which comes with VS2012.

 

Everything runs OK in my local machine until the application is deployed onto a remote server. The issue was that the report content is blank. It seems

no error at all until the debug window of the browser is opened. In the Console tab, it complains that “Ajax client-side framework failed to load”.

 

According to Khaled in the below thread (http://stackoverflow.com/questions/3695351/ajax-client-side-framework-failed-to-load-asp-net-4-0),

it is fixed by having below section:

<system.webServer>
    <modules runAllManagedModulesForAllRequests="true" />
</system.webServer>

 

without changes in Global.asax.
