To preview/export localized reports in different languages, I change the thread's current culture in the report viewer's ExportBegin/RenderingBegin events and reset it back to the original culture in the ExportEnd/RenderingEnd events.
This approach works well in .NET Framework projects but in .NET Core projects, the culture is not reset properly.
Changing the culture in the events of the desktop report viewers should work both in .NET Framework and .NET Core projects.
The Upgrade Wizard for Visual Studio backs up all files, including those in the '.vs' folder. In Visual Studio 2017 this may cause errors when upgrading due to the locked file 'db.lock':
System.IO.IOException: The process cannot access the file 'C:\Users\reportingagentuser\Desktop\reportlibrary1\ReportLibrary1\.vs\ReportLibrary1\v15\Server\sqlite3\db.lock' because it is being used by another process.

The current htmltextbox on the telerik reporter designer does not support html tags for <table>
There is a work around which creates the html text to an image but the quality is not great but more importantly the word wrap functionality is lost.

It would be great if the expressions were validated before leaving the expression editor rather than only finding out I missed a bracket ')' when running the report.
The Preview button of the HTML5 Report Viewer is not styled appropriately when using Kendo SASS themes:
.NET applications do not support rendering extensions like the XPS and MHTML rendering but the Reporting engine attempts to resolve them in such applications regardless.
There should be no attempts to resolve unsupported rendering extensions in .NET applications.
Currently the Webdesigner makes up to 6(?) and the Standalone Designer as much as it needs without(?) limit.
Especially the latter case can quickly lead to a lot of connections, saturating the max allowed connections of a sql server, which also leads to other services depending on a sql server connection to fail.
As far as I've seen, this only happens with Charts in Design mode.
So there are multiple ways to handle this:
See the attached report for a simple example:
It contains a single Datasource, which is a postgres query which simply waits 10s before returning the result.
After updating the DataSource to something which works for you and saving, simply reopen the report and see how many connections are opened in parallel.
With kind regards

Telerik Reporting supports various Barcodes.
It will be very useful if it also supports out-of-the-box Radio Frequency Identification (RFID).
The blog RFID vs Barcode: Comparison, Advantages & Disadvantages elaborates on the difference between the Barcode and RFID and why the latter is preferred in some scenarios.
Using the November 2023 Report Designer, when a resize a Panel and then press Ctrl-Z to undo the resize, all objects within the Panel are lost.
I was able to confirm this by saving as a second copy and then comparing the XML between them.
When the input data of a pie chart is such that some of the series are insignificant enough not to be drawn on the surface area, a DocumentRenderException with the message "The operation was canceled" is thrown by the Reporting engine.
Enlarging the pie chart or hiding/removing its data point labels clears the error.
At the moment, a whole words are removed from text until it becomes short enough to fit in the text box, and this is the only available behaviour.
There should be an option to put ellipsis or clip the text to the textbox width instead (like CSS text-overflow "ellipsis" and "clip").
There's also an older discussion here:
https://www.telerik.com/forums/request-ability-to-show-an-ellipsis-in-a-text-box-when-the-text-overflows-the-available-space
I use HTML content like the below in an HtmlTextBox:
<a style="color: red" href="some link here">some text</a>
The color is not respected when I export to PPTX. The output color of the generated link is always the default blue. In the rest of the formats that support hyperlinks, the color is correct.
I tried to wrap the <a> tag also with <p> and <span> with the same color setting, to no avail.
I am using Kendo UI Spreadsheet control in our project to present Tabular contents that end user can easily modify just like a normal spreadsheet operations and I saved it in database using toJSON method provided by kendo spreadsheet.
When I will get the database driven JSON data from kendo spreadsheet as mentioned above, I want to present it in Telerik Reporting using Table (Datasource of that Table will be from JSON data I saved earlier).
Currently there is no such feature available in Telerik Reporting and I would like to request that feature to be included in future release.
Thanks
I am using the Blazor Web Report Designer widget which when initialized, loads its theme based on the @progress/kendo-theme-default - npm (npmjs.com) theme and overrides the styles in my Blazor application. There is no way to disable the loading of the designer's theme and the application looks inconsistent as a result.
In the Standalone/Visual Studio Report Designers, the distances from the currently selected report item to the nearest elements can be shown by clicking the Show Dimensions button.
We would like to see this functionality implemented for the Web Report Designer too.
When the reporting service fails to generate a report document, the Get Document Info request returns a 500 response with the error message thrown from within the reporting engine. However, instead of displaying the error message in the viewport, the Native Blazor Report Viewer displays a message falsely suggesting that the report is still being rendered when the rendering has, in fact, failed.
When the non-native Excel page header and footer are used (the UseNativePageHeader and UseNativePageFooter XLSX options are set to False) and the SplitWorksheetOnPageBreak property is set to True, the page header section of the report is rendered only on the first sheet, while the page footer section of the report is rendered only on the last sheet.
All Excel sheets should have the page sections present.
If you trigger the 'Clear selection' button of the HTML5 Report Viewer parameter's area, there is no request for a report document with the updated parameter values and the viewer shows the previous report waiting for the user to select parameter values. This problem occurs with both Single and MultiValue parameters with AvailableValues that are non-nullable.
In the Standalone Designer and desktop viewers, in the same scenario, the preview displays a message indicating that the user needs to select valid parameter values.
Some special characters, such as "🍁", break reports that are rendered with the Skia graphics engine in a Linux environment.
When the Gdi graphics engine is used on Linux, the reports are generated successfully. However, the Gdi graphics engine cannot be used on Linux with projects that target .NET 7 and later.
I think navigating over pages by click is boring/complicated, scroll over pages seens to be the standard in the majority of applications.
I know that the HTML5 ReportViewer has the pageMode() property to solve this...
There's a way of implementing the PageModeProperty into the WPF ReportViewer?
