Hello,
I created 6 report files. Each file has its own table, text description and chart. I added these 6 files into a Report Book.

Now I have a question, how do I make a table of contents to correspond to these title in these files, the directory may be similar to the picture

 

Thanks

Hi,

I am using telerik.reporing in my apllication. It was working fine before. But in the morning a strange thing happened, when user clicked the report page, the system displayed an error message 'Parameter is not valid'. I am using telerik:reportviewer to view the report. There was nothing code changed in the server. I do not know what happen, Is there anything would cause this error for telerik report?

Thanks,

I am having a problem with margins when printing my report. I can reproduce the issue by creating a new report, setting the background color of the report header to light gray, and printing it from the designer. By default, my newly created report uses a 1" margin all around and has a width of 6.46". When I print a hard copy of the report, the top and left margins are always larger than the bottom and right margins. Per my measurements, the left margin ends up ~1.125" and the right margin is ~0.875, a 0.25" difference. This becomes more of a problem when I use the 0.25" margins that my customers prefer and things get cut off on the right side (they do not roll over onto another page). Interestingly, printing to a file (using CutePDF or the MS Office Image Writer) or exporting to PDF does not produce the same issue (even if I print the PDFs with no page scaling).

Hi,

I'm porting an old reporting system to Telerik, and I need to adapt the old data provider strategy to a Telerik DataSource that I can use with a Telerik Report.

None of the DataSources provided suit my needs, so I'm thinking about implementing my own extension of DataSource abstract class. I didn't find any suggestion about that in the documentation; is it possible?

 

Thanks in advance and best regards.

I have designed a Telerik report, when printing the report from report viewer, its taking some unique id on the print queue.

How do I document name when printing in Telerik Report viewer.
I found this link when googling,

 http://docs.telerik.com/reporting/m-telerik-reporting-processing-reportprocessor-printreport
but i dont know when it will be called ? where to use this?

Hello,
We are using Telerik Reporting version R2 2020.
In our app to show report we use HTML5 Report Viewer and Web Report designer. Our project based on .Net Core 3.1. Currently, the report viewer is working fine but we have a problem with a web designer. I tested report web designer with a web page using the Chrome browser and it is not working fine. It shows some error messages when loading some report items. For example in my sample project I'm trying to open barcode report with report web designer. After a few seconds It shows some error messages saying "Could not generate the preview of 'barcode N'" (N - barcode number).  

You can see this from the attached picture file. I could not attache my sample project because it allows only picture file.

Here my Startup file.

    public class Startup
    {
        // This method gets called by the runtime. Use this method to add services to the container.
        public void ConfigureServices(IServiceCollection services)
        {
            services.AddCors(o => o.AddPolicy("AllowOrigin", builder =>
            {
                builder.AllowAnyOrigin().AllowAnyHeader().AllowAnyMethod();
            }));

            //This is for showing picture
            services.Configure<IISServerOptions>(options =>
            {
                options.AllowSynchronousIO = true;
            });

            services.AddRazorPages()
                .AddNewtonsoftJson();

            //Designer
            // Configure dependencies for ReportServiceConfiguration.
            services.TryAddSingleton<ConfigurationService>(sp => new ConfigurationService(sp.GetService<IWebHostEnvironment>()));
            services.TryAddScoped<IReportSourceResolver>(sp =>
                new TypeReportSourceResolver().AddFallbackResolver(new UriReportSourceResolver(
                    Path.Combine(sp.GetRequiredService<ConfigurationService>().Environment.WebRootPath, "Reports"))));
            services.TryAddScoped<IReportServiceConfiguration>(sp =>
                new ReportServiceConfiguration
                {
                    ReportingEngineConfiguration = sp.GetRequiredService<ConfigurationService>().Configuration,
                    HostAppId = "Html5DemoAppCore",
                    Storage = new FileStorage(),
                    ReportSourceResolver = sp.GetRequiredService<IReportSourceResolver>()
                });

            // Configure dependencies for ReportDesignerServiceConfiguration.  
            services.TryAddScoped<IDefinitionStorage>(sp => new FileDefinitionStorage(Path.Combine(sp.GetRequiredService<ConfigurationService>().Environment.WebRootPath, "Reports")));
            services.TryAddScoped<IReportDesignerServiceConfiguration>(sp => new ReportDesignerServiceConfiguration { DefinitionStorage = sp.GetRequiredService<IDefinitionStorage>() });
        }

        // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
        public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
        {
            app
             .UseRouting()
             .UseCors("AllowOrigin")
             .UseDefaultFiles()
             .UseStaticFiles()
             .UseEndpoints(config =>
             {
                 config.MapControllers();
             });
        }
    }

    public class ConfigurationService
    {
        public ConfigurationService(IWebHostEnvironment environment)
        {
            this.Environment = environment;
            var configFileName = System.IO.Path.Combine(environment.ContentRootPath, "appsettings.json");
            var config = new ConfigurationBuilder()
                            .AddJsonFile(configFileName, true)
                            .Build();
            this.Configuration = config;
        }
        public IConfiguration Configuration { get; private set; }
        public IWebHostEnvironment Environment { get; private set; }
    }

Can someone help me to solve this problem?
Thank you,

We have a multilingual report that generates report in English and Mandarin (Chinese).

Initial generation of the reports works well. The reporting control displays the reports in both languages in html format. When we attempt to export into pdf following error occurs

[NotSupportedException: Font Arial Unicode MS 12 Bold is not supported.]
   Telerik.Reporting.Pdf.Fonts.TrueType.FontReader.GetFontData(Font font, Boolean& isTTC) +466
.....


Additionally though the export to rtf;excel works excellent in either of the languange. We are using resx files for multilingual capabilities.

Any help would be greatly appreciated. Struggling with this issue for a certain time now.

Hi, 

I'm currently evaluating Telerik Reporting to see if it fits our requirements.

I'm trying to use the "Export a report to a single document to render a report"  to render a very simple report with a single "Hello World" textbox. I used the sample code in the link below.

 

https://docs.telerik.com/reporting/programmatic-exporting-report

I downloaded Telerik.Reporting from nuget.org with version: 13.2.19.1030

I however is experiencing an error once I get to the code:

Telerik.Reporting.Processing.RenderingResult result = reportProcessor.RenderReport("PDF", reportSource, deviceInfo);

 

Error: 

Telerik.Reporting.Xml.UnsupportedVersionException: 'Cannot read a document with the specified schema: http://schemas.telerik.com/reporting/2020/2.0.
You might be using an older version of the product.'

How should I get around this ? 

We're trying to get to a decision soon so can you please help us asap.

Thank You

 

 

 

 

 

 

 

Hi I am a software developer for a software house and we are looking are programming our reports using Telerik. My question is, What are the licensing terms for our clients as they will only need a runtime environment to render the reports and export them to PDF ect. Do they need to purchase full licences or is their another cheaper (possibly free) option for them?
Thanks in advance.

I have a report viewer on my asp.net page and its ReportSource.TypeName is set to the .vb file of my report.  My .vb report has a parameter and I need to pass in a value to it.  The report viewer has its own parameters but these seem to be different than the report's parameters as compiled in the .vb code.  How do I pass a value to the report?  

I have looked through the Telerik documentation and I do not see how to do this.
