I'm trying to implement the REST Custom Report Source Resolver in a .net core web api. But the reports are not showing even the URL is not working. I have used a middleware to connect this to the application. Bellow you can see the regarding. cods.

middleware class

public class TelerikReportingMiddleware
    {
        private readonly RequestDelegate _next;

        public TelerikReportingMiddleware(RequestDelegate next)
        {
            _next = next;
        }

        public async Task Invoke(HttpContext context, IAPIService aPIService)
        {
            string[] path = !string.IsNullOrEmpty(context.Request.Path.Value) ? context.Request.Path.Value.Split("/") : new string[4];

            if (path.Length > 2 && path[2] != null && path[2].Equals("telerikreports", StringComparison.CurrentCultureIgnoreCase))
            {
                if (context.Request.RouteValues["controller"] == null)
                {
                    context.Request.RouteValues["controller"] = path[2];
                }
                if (context.Request.RouteValues["action"] == null)
                {
                    context.Request.RouteValues["action"] = path[3];
                }

                if (!context.Request.Headers.ContainsKey("IntegrationID"))
                {
                    var appId = "1";
                    context.Request.Headers.Add("IntegrationID", appId);
                }
            }

            await _next(context);
        }

        private async Task ReturnErrorResponse(HttpContext context)
        {
            context.Response.ContentType = "application/json";
            context.Response.StatusCode = (int)HttpStatusCode.BadRequest;
            await context.Response.WriteAsJsonAsync("Bad Request: Integration Not Defined, " +
                "Request ID Sould be defined in the Header section of the request");
        }
    }

Report Resolver class

public class BLReportResolver : IReportResolver
    {
        private readonly string _serverPath;

        public BLReportResolver()
        {
            _serverPath = Path.Combine(Directory.GetCurrentDirectory(), "TelerikReports");
        }

        public ReportSource Resolve(string reportId)
        {
            try
            {
                /* get path to report */
                var sourceReportSource = new UriReportSource { Uri = Path.Combine(_serverPath, reportId) };

                //retrieve an instance of the report     
                var reportPackager = new ReportPackager();
                using (var sourceStream = File.OpenRead(sourceReportSource.Uri))
                {
                    var report = (Report)reportPackager.UnpackageDocument(sourceStream);

                    var reportInstance = new InstanceReportSource
                    {
                        ReportDocument = report
                    };

                    return new InstanceReportSource { ReportDocument = reportInstance.ReportDocument };
                }
            }
            catch (Exception e)
            {
                Console.WriteLine(e);
                return null;
            }
        }
    }

controller class

[Route("api/[controller]")]
    [ApiController]
    public class TelerikReportsController : ReportsControllerBase
    {

        static readonly ReportServiceConfiguration configurationInstance =
            new ReportServiceConfiguration
            {
                HostAppId = "TelerikRESTReports",
                Storage = new FileStorage(),
                ReportResolver = new BLReportResolver(),
                ReportSourceResolver = new UriReportSourceResolver(Path.GetFullPath("~/TelerikReports"))
            };

        public TelerikReportsController()
        {
            this.ReportServiceConfiguration = configurationInstance;

        }
    }

what can be the issue?

When using the WPF report viewer the server returns a 404 with the following error:

Note the report still renders but the exception is captured and logged on every report request.

Telerik Reporting is crashing with "Exception message: Font family 'Arial' has no available style"

This is an MVC asp.net framework 4 application using  Telerik Reporting 12.1.18.620 and running in server 2012 via IIS 8.0.9200.16384

There is another app pool on the same server and we installed the same application for a test, and it does not exhibit this issue.

The font does appear to be installed, if we check the Windows fonts.

We have recycled the app pool with this app and the error persists.  We have not rebooted the machine.  We have not re-installed the problematic app yet.

Is there a troubleshooting procedure or steps to correct this issue?

I have tried to implement a web report designer server and i have successfully implemented using  nuget package.  Then i tried to use signed dll files to replace nuget package. I imported "Telerik.WebReportDesigner.Services.dll" and "Telerik.Reporting.Data.Schema.Provider.dll" two dll files and it gives the report designer, but reports are not loading. It keeps showing "An error has occurred. Could not load file or assembly 'Telerik.Reporting.JsonSerialization, Version=17.0.23.118, Culture=neutral, PublicKeyToken=a9d7983dfcc261be'. The system cannot find the file specified." error. What can be the reason for this. Do you have any solution?

Hi mates,

 I have a dataset in a telerik report. The dataset returns a time column. I would like to use the Format function to show it in hh:mm format. If I use Format('{0:hh:mm}', Fields.CreationTime), there is an exception. Currently, I'm using a "manual" transformation, using Fields.CreationTime.Hours + ":" + Fields.CreationTime.Minutes but this is not a solution for me because if the CreationTime is 12:00, the report shows 12:0. I would like to use the Format function OR show the minutes using two digits. How could I resolve my issue, please?

 Thanks a lot in advance.

 Cheers.

I implemented Telerik report viewer in Blazor Hybrid. After viewing the report, I wanted to print that report in the windows and android platforms. With windows build, it works perfectly. but in the android platform it is not working well. After i clicked it redirect to the server URL and download the report as a PDF using browser. Is there any way to print it without downloading it in android?

We're using Azure Reids Cache for our report storage provider. Long running reports result in this error: 
One or more errors occurred.

Does anyone have experience using Azure Redis? Are there additional configuration settings required?

Thanks for your help!

Hello Support,

we use older version 7.0.13.426, 2012 as a part of GMSC. I face an issue with hiding Panel report item. When I set in Bindings both Visible and Style.Visible params to False for sure:

It causes extension of the DetailSection that exceeds to the next page and causes "blank" page. I set yellow background color for the DetailSection (orange is pageFooterSection) to make it more clear.

Could you help me please? This topic seemed to be similar to my issue and the link http://www.telerik.com/support/kb/reporting/details/collapse-the-container-when-hiding-child-report-items- is not working.

Thank you,

Lukas

Hi,

I have designed a report template using web report designer using json data(for invoice pdf).

Now I want to display pdf/report using different data by passing an argument.

I want to use the same template for all invoice pdf.

Kindly explain is this possible in telerik also can you provide a sample code for this?

I am using ASP.net mvc for developing the project
