Hi,

Web Service Data Source has parameters as you can see from the picture below. We can define design-time value for the parameters. The design-time values help us during designing our report (for example, we can see selected properties from standalone & web report designer). In our case, we also need to modify some report programmatically, we need to create new web service data source or update existed one. 

  The question is how to set design-time value for a parameter of web service data source programmatically?

Hi,

We have upgraded our Telerik reporting version to 15.1.21.616 and we are using the Upgrade Wizard to update all the telerik assemblies in the project. When we called /api/reports/formats, below error occurs:

 

"ExceptionMessage": "Multiple actions were found that match the request:  Formats on type WebApi.Controllers.ReportsController GetClientsSessionTimeoutSeconds on type WebApi.Controllers.ReportsController", "ExceptionType": "System.InvalidOperationException",
"StackTrace": "   at System.Web.Http.Controllers.ApiControllerActionSelector.ActionSelectorCacheItem.SelectAction(HttpControllerContext controllerContext)\r\n   at System.Web.Http.Controllers.ApiControllerActionSelector.SelectAction(HttpControllerContext controllerContext)\r\n   at System.Web.Http.ApiController.ExecuteAsync(HttpControllerContext controllerContext, CancellationToken cancellationToken)\r\n   at System.Web.Http.Dispatcher.HttpControllerDispatcher.<SendAsync>d__15.MoveNext()"

 

Once we downgrade back to 15.0.21.224, the error gone.

Please help. Thank you.

Good morning
I have to print a report already created with telerik report designer through a c # application, I looked at the guides but I can't print using the ReportProcessor.PrintReport method.
also is it possible to pass a json file when I start printing with the various data?

How can I get the row count from a table that is in the detail, but show that total in a textbox in the footer?

The datasource on the table in the detail doesn't seem to be accessible from anywhere but the table. 

The datasource on the report itself is different, containing some common items for display, but no data.

I've seen solutions that talk about adding a list or table to the header, but that doesn't seem to be allowed. The report designer does not allow that.  "It is not allowed to add Table to pageHeaderSection1" 

Is there a solution for this? Some way to make a report function that can be called from an expression? Or something like a field in the detail that is identified such that its value can be accessed in the footer?

Thanks

HI All,

We have 2 web servers , 2 app  in our prod environment. Suddenly after server reboot activity, on one of the server we are facing issue "Error registering the viewer with service". When request hit to one of the server then only user see error. We are using File Storage for the implementation. I suspect some settings or configurations might have changed in one server. What all things can we check for this ? Trace log show below error in affected server:
"Make sure you are using CacheStorage inside single-instance application deployment only."

(Test carried out using the BarcodeTypes demo report)

On my development machine, all export formats work fine.

When deployed to Azure, some formats work, some don't:

_ PDF, CSV, XLS, Tiff & MHTML all work fine

_ XLSX, PowerPoint, RTF and Word all give the same GDI+ error

I have found other instances of GDI+ errors on the forum (related to PictureBox, PDF export, ...) but this seems to be a different type of exception

 

I am aware of Report Export issues on Azure with cheap plans, and have upgraded to a higher plan (Basic); PDF export didn't work on cheaper plan and that works now, so I assume this is an unrelated issue.

Error message:

Hi,

I am trying to Implement the RedisStorage in my application which uses Telerik Reporting but doesn't seem to get any hold of it. Can anyone please help me how to use it.

I found some bits of code from long ago but still can't figure it out.

Any up to date clear code You could give me ?  I am using Angular/.NET core 5.0.

I am putting the report in the wwwroot and setting to copy always so the report seems to be there. The report has no parameters.

 

I get the error below


   [HttpGet]
        //https://localhost:44374/reports/testreport
        public string TestReport()
        {
            string webRootPath = _webHostEnvironment.WebRootPath;

            var rptName = Path.Combine(webRootPath, "Reports\\AllForms.trdp");
            var report = new Telerik.Reporting.Report { DocumentName = rptName };
            var instanceReportSource = new InstanceReportSource { ReportDocument = report };

            var reportProcessor = new ReportProcessor();
            var result = reportProcessor.RenderReport("PDF", instanceReportSource, new Hashtable());

            return "xxx";
        }

 

The current data set presented in the report did not produce any significant content, so no pages were generated. If you need to see the whole report content, including blank pages, please contact the report author.
