Trying to preview a report with a lot of data in the report viewer in an ASP.NET Core application results in the error:

"System.ArgumentException: The JSON value of length n is too large and not supported."

Currently, when you set SplitWorksheetOnPageBreak to True, the Excel Sheet name is formed from the DocumentName or ReportName and the number of the page.

It would be very helpful if the report authors can manipulate these names with Expressions.

When I try and create Report1.trdp that already exists in the Web Report Designer definition storage, an Internal Server Error is thrown by Telerik.WebReportDesigner.Services when I debug the designer service. If I continue the execution, the existing Report1.trdp gets overwritten by the new one.

Clicking the cancel button on the HTML5 report viewer show "Report processing was canceled" in the UI but the report is still being generated and rendered on the server.

In this old thread it is stated that it isn't possible to cancel the report generation on the server. Is that still the case?

Telerik report is showing error -

Method Name: Telerik.reporting.PictureBox.Set_Value - Parameter is not valid. 

 Above highlighted line gives an error during component initialize.

It was working earlier, but now showing this error, even there is no code change. Please help.

 

Your help is highly appreciated.

We need our reports to have editable text fields where data can be entered into the pdf document and printed.

See also the Forum thread export pdf with editable text areas.

Bindings are not available when multiple report items are selected in the Web Report Designer

What's the long-term plan for supporting Linux and Telerik Reporting? The dotnet design team is looking to remove support for System.Drawing.Common on Linux platforms. They're recommending compiler warnings in .Net 6, and full PlatformNotSupportedExceptions in .Net7

It seems that the MultiSelect Combo Box Filtering does not work in the Report Viewer. o be smaller if the user starts typing

We are using Telerik reporting R2.2022 version in our project. Some of our reports have html link (created with tag “a”). If we preview those reports html link doesn’t act as an actual hyperlink, so it’s not clickable. We know that there is a HtmlTextBox limitation not to be interactive in WinUI report viewer. But this is important for us to be able to click on html link on WinUI and we need that functionality.  

I tested WinUI example project (CSharp.WinUIExample.VS2022.sln) and opened SwissQRBill.trdp report. The report has some links to the external source in internet, which is not clickable, but if you open it in Standalone report designer it’s clickable.  

Is it on your roadmap to implement that feature? 

Thanks,

Optimize the Telerik Reporting performance by parallelizing the reporting paging and rendering. Better utilize CPUs with multiple cores and as a result, improve the REST Service throughput and decrease the viewers' rendering times.

 In the Word rendering, there is sometimes space between the footer and the body of the document.

 

Please, add a .zip or .7zip with the following content from the Telerik Reporting folder:

• all runtime assemblies- everything from the Bin folder without the Design folder and VS<Version> (for example VS2019, VS2022, etc) folders
• Html5 folder
• License Agreements folder
• Silverlight folder
• Wpf folder

When generating a report with multiple tables provide the ability to send these tables to different workbook tabs when exporting to Excel

The parameters' area splitter's expand icon gets hidden when the area is shrunk.

When there is a textBox report item placed in a report page header/footer section with a text color styling applied to the textbox, the text color is not respected in the Excel export.

This happens only when the native excel page header/footer is used.

We are using Telerik Report Viewer in our ASP.NET MVC application. I've read the documentation about localizing the report viewer (https://docs.telerik.com/reporting/html5-report-viewer-localization) and most of the texts are localized now, but there are some other that I can't change.

For example, in the search menu, result list, 'page xx' text.

Can you add this string resource in the resources file?

Code128 Barcode does not always pick the correct subset for the given input value

For example, the string A12B34C56D

The barcode generated when using the Code128 encoder is longer than the barcode generated when using the Code128A or Code128B encoders.

When the font that is used to generate the report is not installed on the client machine, some of the text may be cropped

t would be very useful to be able to embed fonts in DOCX and the other OpenXMLs, as in PDF.
