When a new HTTP project is created in Vista or Windows 2008 Operating System (or newer), the default application pool is using DefaultAppPool, which uses IIS 7.0 (or newer) Integrated .NET pipeline mode. Intersoft’s components use several HttpHandlers for managing resources and chart engine. This article guides you to migrate the existing application configuration file to take advantage of the IIS 7.0 (or newer) Integrated pipeline mode.

Should the problem persist after follow the method to add the configuration, please send us your web.config file so that I can assist you further.

For IIS version below 7 and Classic Pipeline mode, you can define httpHandlers and httpModules element to the system.Web element. Example:

<configuration>
  <appSettings>
    <add key="ISNet.WebUI.ISRes_Registered" value="true"/>
    ...
  </appSettings>

  <system.web>
    <httpHandlers>
      <add path="ISRes.axd" verb="GET" type="ISNet.WebUI.WebResourceHandler, ISNet.WebUI, Version=3.0.5000.1, Culture=neutral, PublicKeyToken=b1f2a8511635667a" validate="true"/>
      <add path="ISChart.axd" verb="GET" type="ISNet.WebUI.WebGrid.Chart.ChartRequestHandler, ISNet.WebUI.WebGrid" validate="true"/>
      </httpHandlers>
      ...
  </system.web>
	
</configuration>

For IIS 7+ and Integrated Pipeline mode, the handlers and modules element to the system.webServer element. Example:

<configuration>
  <appSettings>
    <add key="ISNet.WebUI.ISRes_Registered" value="true"/>
    ...
  </appSettings>
  
  <system.webServer>
    <validation validateIntegratedModeConfiguration="false"/>
    <handlers>
      <remove name="ISRes.axd_GET"/>
      <remove name="ISChart.axd_GET, POST"/>
      <add name="ISRes.axd_GET" path="ISRes.axd" verb="GET" type="ISNet.WebUI.WebResourceHandler, ISNet.WebUI, Version=3.0.5000.1, Culture=neutral, PublicKeyToken=b1f2a8511635667a" preCondition="integratedMode"/>
      <add name="ISChart.axd_GET, POST" path="ISChart.axd" verb="GET, POST" type="ISNet.WebUI.WebGrid.Chart.ChartRequestHandler, ISNet.WebUI.WebGrid" preCondition="integratedMode"/>
    </handlers>
  </system.webServer>
  ...
</configuration>

I enclosed the modified version of web.config file as attachment. Please have the modified file evaluated on your end and let me know whether it helps or not.

Hi Yudi, now the error 500.23 disappeared but I'm getting the following errors/problems:

MS IE 11 - see the attachment screenshot shown from the debbuger

Firefox 43.xx - the filter icons aren't displayed, only dots .... instead.

Moreover, using WebGrid designer I got the error: Intersoft componet Editor for VS 2012 is either not installed or corrupted. ...

I tried  solving the problem applying the solution found in the comunity date February 27,2013 but the error persists.

Attached web.config + debbuger screenshot.

Thanks.

Regards.

Luciano

Hi Yudi, now the error 500.23 disappeared...

Glad to know that after configure the handlers and modules declaration in web.config file, the site now works on IIS 8.5 and Integrated Pipeline mode. Error 500.23 no longer persist.

... but I'm getting the following errors/problems:

MS IE 11 - see the attachment screenshot shown from the debbuger

I suspect that you might use older version of WebGrid and WebUI.NET Framework 3.0. I recommend you to apply latest build of WebGrid 9 and WebUI.NET Framework 3.0 in order to resolve the problem on IE 11 browser.

If the issue still persist after apply latest build of WebGrid 9 and WebUI.NET Framework 3.0, please feel free to let me know.

Firefox 43.xx - the filter icons aren't displayed, only dots .... instead.

I tried to reproduce the reported problem by rendering the live sample of Filtering.aspx in Firefox 43.0.2 with no luck. The filter icon displayed without any problems.

Please ensure that you have applied latest build of WebGrid 9 and WebUI.NET Framework 3.0 and let me know the result.

Moreover, using WebGrid designer I got the error: Intersoft componet Editor for VS 2012 is either not installed or corrupted. ...

Try to remove ISNet.WebUI.WebGrid.Editor.dll and ISNet.WebUI.WebGrid.Editor.Metro.dll from GAC, then update ISNet.WebUI.WebGrid.Editor.dll and ISNet.WebUI.WebGrid.Editor.Metro.dll (%programfiles(x86)%\Intersoft Solutions\WebUI Studio for ASP.NET\WebUI.NET Framework 3.0\Bin) in GAC. You can use gacutil command to do this. Please check the detail command in here.
