MVC ReportViewer Not loading for huge reports

Question

I am using ASPX report viewer control in my MVC application and its working fine in normal cases. In some cases while i am trying to load a report that took some time load (query execution for the report's dataset is taking more than 3 minutes ) and the report viewer itself is not loading in to the MVC web portal

While checking the network console i can see an error like below

 ReportViewerWebForm.aspx net::ERR_CONNECTION_RESET 200  

Any known reason for this error and any way to resolve this timeout kind of error

Answer 1

Try increasing executionTimeout through web.config, which sets the allowed execution time for the request:

<configuration>
 <system.web>
   <httpRuntime
    maxRequestLength="1048576"
    executionTimeout="3600" />
 </system.web>
</configuration>

According to the docs, that property indicates the maximum number of seconds a request is allowed to execute before being automatically shut down by ASP.NET. (Defaut is 110 seconds)
