When a report fulfills the following conditions :

 1. Is Multicolumn;
 2. Has DocumentMapText set;
 3. Contains a List (data item) with DataSource set with Bindings to a field of the Report DataSource.

and is displayed in PrintPreview mode in the WPF Report Viewer, an exception like :

"Could not register named object. Cannot register duplicate name '_20aa3785775c4790ba0cfa8021bd8433' in this scope.' Line number '1' and line position '2567'. Cannot register duplicate name '_20aa3785775c4790ba0cfa8021bd8433' in this scope." is thrown.

Telerik.Reporting.OpenXmlRendering.2.7.2.dll from the latest release (R1 2009) references the from version of DocumentFormat.OpenXml. See the screenshot:

Here the screenshot for the prev version (R3 2018 SP2):

Because of this our projects referencing DocumentFormat.OpenXml 2.8.1 (the latest version) are all broken. Xlsx rendering simply does not work anymore.

When opening the Edit Expression dialog, the state between HTML view and Design view is lost when using build-in functions, but it keeps the value if it is a simple text with formatting.

Telerik.ReportViewer.Mvc.SendEmail class in Telerik Reporting ASP.NET MVC does not contain fields "Cc", "Subject", "Body" (https://docs.telerik.com/reporting/t-telerik-reportviewer-mvc-sendemail)

But JS documentation dontains such fields (https://docs.telerik.com/reporting/html5-report-viewer-jquery-fn-telerik-reportviewer#sendEmailOption).

I'm using the latest version of kendo ui and telerik reporting.

1. open reportviewer
2. click send email button
3. populate all fields in send email window
4. copy was not received by recipient from "Cc" field

Please note that Cc field is empty on server side.

On attempt to display reports in Print Preview in Angular applications, an error is thrown if continuous scrolling is enabled.

Possible workaround: Disable continuous scrolling by setting the pageMode option to 'SINGLE_PAGE'.

I add some Datasources, some Report Parameters depending on that datasources without issues. But as soon I add a "HtmlTextbox" to the report and I build it, one (or more) data source(s) disappear.

Additional information:
- Visual Studio 2015,
- Telerik Reporting version 12.2.18.1017,
- Reproducible only in Visual Studio Report Designer

For now, Telerik Reporting is supporting SQL Server data provider only. Once the .NET Standard  2.1 Is live, please include the support for multiple data providers.

I want to define conditional formatting on table row, after I define a filter and save it, I can not save the conditional formating dialog, it gives exception.

What am I doing wrong?

 

When you have some <br /> tags in the HTML, the behavior is different between Kendo Editor and Telerik Reporting.

I attached HtmlTextBox result and Kendo Editor behavior. 

in the real world, an exception can really occurs in the resolve method, and I want bubble this unknown exception coming from resolve method and not a custom exception written in GetParameters method

The ExportDialog window in Windows Forms Report Viewer does not respect resource files for localization and displays always the default text.

The Fonts meta information in the PDF rendered document is incorrectly populated. It contains entries for missing Font subfamilies, i.e not available during report rendering. We observed this with Franklin Gothic Medium Condensed font that has only Regular subfamily.

I am currently using the Telerik Reporting 13.0.19.222 software to generate an annual report that we will send to our constituents. I can render the report to a multi-page PDF for emailing and local archiving with no PDF standard or PDF/A-3b just fine. However, we intend to send the rendered PDF reports out to be printed and mailed by a publishing company that has requested that the documents comply with the PDF/VT standard.

Is this something that is being considered and/or implemented in a future release?

Thank you in advance,

The rotated text using Times New Roman font appears truncated in the Html5 Report Viewers. The text is properly rendered in formats other that Html.

If the command for fetching Report Parameter AvailableVlues times out, the WPF Viewer freezes with hidden parameters' area, i.e. it is not possible to enter other values and the application needs to be restarted.

It would be great if all the localizable/localized strings/resources can be exported, e.g. into an Excel file, so they can be given to a translator and imported once translated

I would like WPF viewer to behave like WinForms viewer and to keep the content of the rendered in XAML report in the page area in case of exceptions when exporting in other formats.

When attempting to export a report in Excel 97-2003 format, an exception is thrown: 

"The type initializer for Telerik.Reporting.Excel 97.Workbook threw an exception. Object contains non-primitive or non-blittable data."

As HTML, PDF and OpenXML-based renderings are supported on Linux/macOS machines, please remove the old Excel 97-2003 format.

Hi Team,

 

As Heat maps are not supported by Telerik reporting, Could you please let me know if you have workaround solution readily as a demo . If not please suggest the which third part libraries to be used in C# solution.
