Value cannot be null. Parameter name: key

I am using ASP.NET MVC 4.0 (System.Web.MVC v 4.0.0.1) and would like to use Stimulsoft (Ultimate version 2014.3.0.0) as our report engine.
Below is the code in my View:

Code: Select all

<body>
    <div>
        @Html.Stimulsoft().StiMvcViewer(
    "ReportViewer1",
    new StiMvcViewerOptions()
    {
        ActionGetReportSnapshot = "GetReportSnapshot",
        ActionViewerEvent = "ViewerEvent",
        Controller = "Print",
        Width = Unit.Percentage(100)
    })
    </div>
</body>

And below is my actions in PrintController:

Code: Select all

public ActionResult GetReportSnapshot()
{
    var report = new StiReport();
    report.Load(Server.MapPath("~/Content/Print/Ticket_Single.mrt"));
    report.Dictionary.Clear();
    report.RegData(GetReportData()); // GetReportData method return a dataset
    report.Dictionary.Synchronize();
    return StiMvcViewer.GetReportSnapshotResult(HttpContext, report);
}
public ActionResult ViewerEvent()
{
    return StiMvcViewer.ViewerEventResult(HttpContext);
}

I have also added an assembly binding for ASP.NET MVC v 4.0.0.1 in web.config:

Code: Select all

 <runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <probing privatePath="widgets;modules/temp" />
      <dependentAssembly>
        <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" />
        <bindingRedirect oldVersion="0.0.0.0-4.0.0.1" newVersion="4.0.0.1" />
      </dependentAssembly>
    </assemblyBinding>
  </runtime>

Code works fine and reports are displayed with no problem on my machine (Visual Studio 2013 Update 3).
But in a similar dev machine (same VS version installed + same Stimulsoft version installed) I get System.ArgumentNullException in the view. Below is the full stack trace.
I suspect there could be some conflicts between ASP.NET MVC 4.0.0.1 and this version of Stimulsoft (Works fine on my machine though!)
A similar problem has been discussed at http://stackoverflow.com/q/30272387/337294 with ASP.NET MVC 5.2.

Below is the full stack trace:

I'd appreciate if you guide me to solve/work around this problem.
P.S. Unfortunately, using flash based solution is not an option due to company policies.

Hello.

Please, check the Web.config file. There should be used version of MVC.
If you use MVC 4 then it should be next:

Code: Select all

<runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" />
        <bindingRedirect oldVersion="1.0.0.0-3.0.0.0" newVersion="4.0.0.1" />
      </dependentAssembly>
    </assemblyBinding>
  </runtime>

If this is not help, please, send us a sample project and information of installed .Net Framework and MVC where you get the error.

Thank you.

As I have mentioned in my first post, I have already added that bindingRedirect to my web.config and I am using Visual studio 2013 on Windows 8.1
I have converted one of your samples to MVC 4.0.0.1 and tested it on both machines. I still get the same error on one machine while it's working fine on the other.
I attached your sample project which I have updated to MVC 4.0.0.1.

Let me know if you needed further information.

Hello.

We have reproduced the issue on our 2014.3.0.0 build.
But there is no such error on our latest prerelease build.
Please, download it from our site and try.

Thank you.

I have same problem too on MVC 5 (System.Web.MVC v 5.2.3.0) and Stimulsoft (Ultimate version 2014.3.0.0)
<assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" />
<bindingRedirect oldVersion="1.0.0.0-5.2.3.0" newVersion="5.2.3.0" />

We still face the same problem in Ultimate 2015.1 version.
I have tested the same project I have attached in my previous post with 2015.1 version.

Hello,

Please use latest prerelease build 2015.1.16.

Thank you.

I have the same issue issue using Stimulsoft Reports.Ultimate 2014.3 , MVC5 and visual studio 2013 and please notice the following:

1- i used the Stimulsoft sample and it is not working.
2- the only working sample was the FX viewer which need flash player to be installed on client browser (correct me if i'm wrong).

Thank You

Hello, Mohammed.

Could you specify what sample do you use? Do you get any error? Please, describe the issue more detailed.
All our samples are working.

Thank you.
