I was using the service in Framework 4.8 but migrating to .NET 8 and I'm trying to reference an assembly that uses some functions in the reports.
How do I reference?

he only place I found was this one but it doesn't work.

assemblyReferences Element Configuration - Telerik Reporting

When I copy and paste existing table from telerik report designer. i am getting below error

I set datasource and table from code.

how can we create a new table using the same datasource(which we set in code) from  designer?

I created a report using Telerik Report Designer Standalone with sqlDataSource1 setup with the following ReportParameters like this:

C# coded that read that send the parameter as Int32

    var reportProcessor = new Telerik.Reporting.Processing.ReportProcessor();
    // set any deviceInfo settings if necessary
    var deviceInfo = new System.Collections.Hashtable();
    var reportSource = new Telerik.Reporting.UriReportSource();
    var directory = Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().Location);
    var value = Convert.ToInt32(numericExportarPdf.Value);
    reportSource.Uri = "Report.trdp";
    reportSource.Parameters.Add("NRO_TICKET", value);
    Telerik.Reporting.Processing.RenderingResult result = reportProcessor.RenderReport("PDF", reportSource, deviceInfo);
    if (result.HasErrors) return;
    string fileName = result.DocumentName + "." + result.Extension;
    string path = Environment.GetFolderPath(Environment.SpecialFolder.DesktopDirectory);
    string filePath = Path.Combine(path, fileName);
    using FileStream fs = new FileStream(filePath, FileMode.Create);
    fs.Write(result.DocumentBytes, 0, result.DocumentBytes.Length);

Telerik.Reporting.Processing.CancelProcessingException: An error has occurred while processing the report. Processing canceled. Check the InnerException for more information.

Hello.

Currently I am designing a report on which I have date and datetime data types.

I have prepared the data-base table with data that goes into the report (attachment data-model.png)

I prepared report template in telerik web report designer (attachment report_template.png)
I set format according to Standard DateTime Format Strings
Field with date data has format {0:d}

On preview (at Web Report Designer) the date seems to be ok (attachment preview.png)

Unfortunately, after exporting the report to excel (xlsx), the date type is not a date in excel (attachment invalid_format.png)

My appsetting.json file contains

"telerikReporting": {
  "extensions": [
    {
      "name": "XLSX",
      "parameters": [
        {
          "name": "UseExtendedFormatting",
          "value": "False"
        }
      ]
    }
  ]
}

What should I have to set/do in order to have date format in excel for cells that contain date and date-time data?
I would like to achieve result like below: for cell that contain date data in report I need date format in excel

I would like to emphasize that Standard Numeric Format Strings work:

• C or c (Currency) works fine
• N or n (Number) works fine
• G or g (General) works fine
• P or p (Percent) works fine

Environment:

• Visual Studio 2022
• .NET 6
• Web report designer written in Razor pages
• Packages (I know it's not the latest version, but it works the same badly on the latest version)
  • Telerik.Reporting v. 16.2.22.1109 (v2022.3.1109)
  • Telerik.Reporting.OpenXmlRendering v. 16.2.22.1109 (v2022.3.1109)
  • Telerik.WebReportDesigner.Services v. 16.2.22.1109 (v2022.3.1109)
• jQuery v. 3.6.0
• Windows culture pl-PL
• I run my project on IIS
  • IIS version 10
  • culture pl-PL
• project culture pl-PL
• I set kendo.culture("pl-PL");
  • culture file https://kendo.cdn.telerik.com/2022.3.1109/js/cultures/kendo.culture.pl-PL.min.js

Hello,

I've created a report in standalone report designer with custom function. And saved it in trdp format.

I added a custom function and connected the assembly as described in this manual.

In the report editor, I see my function and use it, however when I try to use this report for printing, my function becomes unavailable.

public class BaseReportBook<TModel> : ReportBook, IDisposable
{
    public virtual byte[] CreatePdf(TModel model, ReportTypeEnum reportType)
    {
        var reportPackager = new ReportPackager();
        using var sourceStream = File.OpenRead(Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "Reports", reportType.GetDescription()));
        var report = (Telerik.Reporting.Report)reportPackager.UnpackageDocument(sourceStream);

        report.ItemDataBinding += new EventHandler((sender, e) => Report_ItemDataBinding(sender, e, model));
        InstanceReportSource reportSource = new InstanceReportSource();
        reportSource.ReportDocument = report;
        ReportSources.Add(reportSource);

        ReportProcessor reportProcessor = new ReportProcessor();
        var instanceReport = new InstanceReportSource();
        instanceReport.ReportDocument = this;
        RenderingResult result = reportProcessor.RenderReport("PDF", instanceReport, null);

        if (result.Errors.Length > 0)
            throw new Exception(string.Join("\r\nError: ", result.Errors.Select(s => s.Message)));
        return result.DocumentBytes;
    }

    private void Report_ItemDataBinding(object sender, EventArgs e, TModel model)
    {
        Telerik.Reporting.Processing.Report item = (Telerik.Reporting.Processing.Report)sender;
        item.DataSource = model;
    }

    protected override void Dispose(bool disposing)
    {
        base.Dispose(disposing);
        GC.SuppressFinalize(this);
        GC.Collect();
    }
}

reportType.GetDescription() returns the name of the report (e.g. test.trdp)

The report is successfully generated, but it does not see my function. Although they are in the same assembly.

When viewing the preview in the editor, the function works:

Here is the function itself:

public static class CustomFunctions
{
    [Function(Category = "Images", Namespace = "Extension", Description = "Images")]
    public static Image GetLogo() => new Bitmap(Properties.Resources.logo);
}

Hi,

Arabic reports work well on Windows, but when the app is published to Docker, the report viewer shows the correct report, but when printing or exporting PDF, the report is drawn from left to right with incorrect format and layout.

Here is an example of a Docker PDF

, but this is the correct report on the Report Viewer

Hello!

Facing a very strange issue: when I updated from  16.1.22.622 to the latest one 16.2.22.1109 list-based filters are selecting in a weird way: select all/deselect all is working. Still, individual values are not switching correctly (as I can see the parameter aria-selected is not changing properly).

The only real update was related to this version switch (had to do it as I can't find a previous version of a standalone Report Designer - for some reason can download only the latest one - and right now schema changed so I can't use new report files with an older package). 

Any ideas about what can be a reason? A quick comparison of existing minified JS doesn't show any significant changes. We are using .NET 5.

Any direction would be quite helpful.

Best regards & stay safe.

I want to create a report which includes one section (likes multi-column report) and another section (like one -column report), more detail on the attached file.

After researching, I haven't found the solution yet.

So Could Telerik builds this kind of report??

Thanks!

Hello.

Reporting3.PNG is Telerik Report Designer Screen,

Reporting1.PNG is Telerik Report Viewer Screen,

Reporting2.PNG is Telerik Report Viewer Print Screen,

I'm going to put all the components in the outermost rim. Running the Telerik Report file, working in the Telerik Report Designer, all components are within the outermost border, but on the Telerik Report Viewer and print screen, the number 3000 is located in different locations and is also out of the border.
All components have values of location (ex. 250px, 34px) and size, and values of CanGrow and CanShrink are False. Multiline is also false.

And then, this is my Html5Viewer

@{
    ViewData["Title"] = "Label";
}
<style>
    #reportViewerLayout {
        position: absolute;
        left: 0px;
        right: 0px;

        overflow: hidden;

                // Sets the scale mode of the viewer.
                // Three modes exist currently:
                // FIT_PAGE - The whole report will fit on the page (will zoom in or out), regardless of its width and height.
                // FIT_PAGE_WIDTH - The report will be zoomed in or out so that the width of the screen and the width of the report match.
                // SPECIFIC - Uses the scale to zoom in and out the report.
                scaleMode: telerikReportViewer.ScaleModes.SPECIFIC,

                // Zoom in and out the report using the scale
                // 1.0 is equal to 100%, i.e. the original size of the report
                scale: 1.0,
                enableAccessibility: false,

                //If set to true shows the Send Mail Message toolbar button
                sendEmail: { enabled: false },
            });
    });
</script>

1. I wonder why the values of telerik designer and viewer are different, and the values of viewer and print are different.
2. I want all the components in the attached picture to be in a specific location within the outermost frame, as I worked on the designer.

Please help me.

Best regards.
