Telerik Report Services Implementation Issues!!!

[Trung]

Hi guys, I am interested in using the Telerik Report Web Services for my company; however, before I can make a final decision on this, I will need to clarify on a few implementation areas to see if this fits into our company's projects. Here is the story ....

I have successfully created a Telerik report web service based on the instruction on your website but.....I wonder

• if it is possible to call Telerik Report web services from other web services and manipulate "data object source" as well as "report parameters" on the runtime. For example, I have a service call Reports (ASP.NET Core project targets .Net 4.7.1) which handles all of the report generation requests from the UI, this service processes and handles all the report-generation requests (based on the business logic) then generate a business Object contains information for generating PDF, XLSX files. I would like to send this business object to the Telerik Report web service together with Report Parameters so a report (PDF, HTML, XLSX) can be generated.
• Same as above but between 2 different controllers, ReportController (for handling business logic and generate required data) and TelerikReportsController (for generating report File).
• In both scenario, is it stills possible for me to use Telerik Report Viewer on the client side

Examples, diagrams, map, source code to the above problems would be appreciated as I may need them to convince my bosses

Hello Trung,

You can work with Reporting REST service either through a report viewer or manually (by sending requests to the service endpoints). The list of REST service methods is provided here.

To display reports in a web application, you can use HTML5 report viewer that will communicate the server where the reports are generated using Reporting REST service. Any run-time modifications to a report can be placed inside custom report resolver used by the service.

I can suggest the following help articles for more detailed information on how to use the viewer and the service:
How To: Use HTML5 Report Viewer in an application
How To: Add Telerik Reporting REST Web API to Web Application
How To: Implement a Custom Report Resolver

I hope this information will help.

Hi Katia, thanks for your response. I have tried all of the options you have mentioned but I could not get the Rest API service to work at all. In particular, When I send the request to register , everything went smoothly; however, if I tried to make any other API calls such as Get Parameters (POST request), the Report Service always return the error "415 Unsupported Media Type". This behaviour only when I create the Rest API under .net Core 2.0 Template but .Net Framework 4.6.1. I am thinking of using now unless this problem resolved....

Hi Katia,

Unfortunately, the problem stills remain....

I guess my question has not been explained clearly. 

I have tried to set up the service on .net Framework without any problem ( usable with Postman, HTML viewer, pure Javascript..etc, the issues only happen if I try the service running Net Core. Whichever request I send to this report .Net core services (except the Register Client), the service throw back the error 415 Unsupported Media. This error only happens if I try to use Postman or javascript client but not from Telerik HTML Viewer

Hi Katila,

I have figured out the problems. The cause is due to my setup and configuration of the project. Everything works now. 

Thanks for your help
