woodlumb

Webreport is don't load on ie and firefox browser ( like on attachment). I have set WebMode = true. Another computer is OK. Where is the problem?

ipong

try to debug in firefox, i believe there is an error in XHR request

woodlumb

I don't get any request . In debug i look ProcessRequest(HttpContext context) function dont' run. Where the problem is?

the mechanism of fastreport web is :
1. returning html which contains anitmated progress picture and a syntax to call webservice via ajax/xhr script, to enable calling webservice, you need to attach :
(note: MVC Razor style)
@WebReportGlobals.Scripts()
@WebReportGlobals.Styles()

2. in web.config, you must set webhandler to enable webservice
in system.web section:
<httpHandlers>
<add path="FastReport.Export.axd" verb="*" type="FastReport.Web.Handlers.WebExport" />
</httpHandlers>

in system.webserver section:
<handlers>
<add name="FastReportHandler" path="FastReport.Export.axd" verb="*" type="FastReport.Web.Handlers.WebExport" />
</handlers>

I have it all. On my computer works properly. On another dont' work (another server , the same application). Maybe IIS configuration is not properly.

ipong

double check the IIS installation features from the control panel (Programs and Features -> Turn Windows Features on and off -> Internet Information Services -> World Wide Web Services -> Application Development Features).

and

application pool in IIS Manager, another reference : https://msdn.microsoft.com/en-us/library/aa560277.aspx

Maybe limit requests on IIS for FastReportHandlar ?

Interesting.....are you using Web Farm and Web Garden architectures?

from documentation :
To use the FastReport report generator in a multi-server (Web Farm) or multi-processor (Web
Garden) architecture there are additional requirements for creating special storage for data
synchronization between WebReport objects.

I know where is the problem. When is set application pool on 'Classic' mode , FastReportHandler isn't set on IIS in mapping service( isn't read from web.config ).
It have to be 'Integrated' mode. But why isn't work on 'Classic' mode?

Read this : https://blogs.msdn.microsoft.com/tmarq/2007...-preconditions/

IIS uses http handlers from both <system.web><httpHandlers> and <system.webServer><handlers>.

The solution is add precondition: integratedMode, therefore, if you use 'classic mode', IIS will not use handler with precondition 'integratedMode'

  <system.webServer>
    <handlers>
      <add name="FastReportHandler" path="FastReport.Export.axd" verb="*" type="FastReport.Web.Handlers.WebExport" preCondition="integratedMode,runtimeVersionv4.0" />
    </handlers>
  </system.webServer>

You have right. It's work. I had to be added <validation validateIntegratedModeConfiguration="true" /> in 'classic mode' .

<system.webServer>
    <handlers>
      <add name="FastReportHandler" path="FastReport.Export.axd" verb="*" type="FastReport.Web.Handlers.WebExport" preCondition="integratedMode,runtimeVersionv4.0"/>
    </handlers>
    <validation validateIntegratedModeConfiguration="true" />
  </system.webServer>
