I am attempting to test Reporting in MVC 6, however, I am unable to find the Nuget package referenced in the documentation. Can someone please attach this package, or provide a link to where they can be found?

Hi Tim,

Telerik Reporting MVC 6 packages were last updated in Q3 2015 v9.2.15.930 by using MVC6 beta6. Since then there are new beta versions of MVC6, thus we decided to to pause the further development of the Nuget packages until the official release of MVC6. The packages are not tested against the latest MVC6 updates.

If you want to test the packages included in v9.2.15.930, you can download them after logging into your account and navigating to Products & Subscriptions - DevCraft - Download - Reporting - Older versions - v9.2.15.930.

Note that the purpose of the available packages is only educational, and our recommendation is to use the old web projects templates provided by Visual Studio with the HTML5 Viewer.

Hello,

Has there been any additional work done on reporting for MVC6? It's holding up moving forward with a project that needs to be moved from MVC5. If nothing has been done are there any workarounds at this point? Is it possible to use the HTML5 control? If so, I assume this means there would be additional manual configuration.

Thanks for any suggestions,

Scott

Hello Scott,

There is MVC6 RC1 and we built the reporting Nuget packages with this version. The steps are as in HTML5 Report Viewer and ASP.NET 5 , where the difference since MVC6 beta6 is that the wwwroot/web.config is totally ignored and connection strings must be hardcoded in reports or you will need a custom resolver for the Reporting REST service to update the data items DataSource properties at run-time.
Packages are still for educational purpose, until there is an official release we do not recommend using them in application for production needs.

Other approach is to use the HTML5 Viewer and host the Reporting REST service in a standard web application with enabled CORS.

I hope this information is helpful.

Stef,

I've followed the steps detailed but cannot get the report to display. I don't have any errors the page just displays, "Loading..." and nothing ever appears. It appears everything is loading and firing but I am at a loss as to where things are breaking down. Attached is a screenshot of what I'm seeing and the network load of resources and web api calls. Any thoughts on what may be going wrong is appreciated. The only thing that was a little weird when putting the project together is when I use the line:

I get an error saying it was expecting ";" and it fails. To correct it I just moved that .js file to a webserver and referenced it without the Url.Content piece. Could that be messing me up? I saw there was a note about having to use Url.Content but I couldn't get it to work with that javavscript file however it does appear to be fine when used for the ServiceUrl and the TemplateUrl.

Thanks for any guidance,

Scott

Actually I just see now where it is failing during a look for a pdf plugin as shown in the attachment. Does that matter?

Sorry for the many posts but I just installed Acrobat and it isn't failing at that point any longer but the report still does not display, only the "loading..." text.

Hi Scott,

Please check the response from the server, and if it contains the report rendered in HTML. If yes, check if the DIV element hosting the viewer's object is sized correctly via CSS rules.

The recommended troubleshooting approach is to use Fiddler or other proxy tool to check the requests, their responses and statuses. Information about requests and responses content can be seen in Fiddler - Inspectors - Request/Response - Raw tabs. This will let you check requests to the Reporting REST service and if the URLs are correct (if relative paths are resolved correctly).
Note that relative paths may need adjustment depending on how the application is hosted.

Feel free to open a support ticket and send us the log file generated by Fiddler.

Stef

Thanks Stef.

I used Fiddler and examined the traffic of a working HTML sample and it looks like everything is going fine all the way up until the last API statement. I get two /info GETs and then the /pages/1 API call that should take place never does. Any ideas on what might cause that? Working on a proof of concept and would love to get this going.

Thank you so much,

Scott

Also, if I execute the GET .../pages/1 command in Fiddler it is properly returning the data including the HTML you would expect.

Solved...mostly.

For others, my problem had to do with this line.

It was not working properly as in my startup file I was not running this line:

app.UseStaticFiles();

After that things worked just fine...almost. I am left with a toolbar that I not displaying correctly; it looks like a mobile version and is stacked using only text and no icons. I've attached a picture. Also, Fiddler shows this error:

Name Protocol Method Result Content type Received Time Initiator
http://localhost:7430/api/reports/resources/styles/telerikReportViewer-css HTTP GET 404 0 B 53.82 ms link

How do I correct it and will this fix my formatting? I think it probably will.

Thank you,

Scott

I was not including the "telerikReportViewer.css" stylesheet.

All is good now.

Thank you

Hello Scott,

Thank you for the updates.

About the last problem, the viewer's HTML template is requested as .html file from the Reporting REST service. The HTML template contains two links to the viewer's CSS template file and icons font. If you have issues performing the requests in this manner, each file can be linked from the page directly, and the viewer will not request the files from the Reporting REST service.

Hello Stef,

We just started a new reporting project. Now do you recommend Telerik reporting with Asp.Net Core or do we need to go with MVC5?

Thank you,
Poorni

Hello Poorni,

The type of project depends on your custom requirements and the platforms you need to support. The HTML5 Viewer can be used in any web application, where the usage of the Reporting REST service in the same project is not mandatory.

If the project will be hosted on a Windows OS, targeting standard .NET 4+ framework, the service can be in the project. If you will target different platforms, the service can be hosted separately.

For more details, please check How To: Use HTML5 Report Viewer in an application and HTML5 Report Viewer in ASP.NET Core (updated).

Stef
