When a report is saved in the Web Report Designer, a popup appears confirming that the report was successfully saved. However, it is visible for far too long and blocks users during this time.

This feature request is to add an 'ok', 'hide' or 'close' button to these types of popups so the user can dismiss it.

Thank you,

Shannon

Release 2026 Q2 (20.1.26.707)

Hi there,

Adding an external style sheet to a report in a report-book triggers an error when previewing the report book, "Object reference not set to an instance of an object" 

I've attached the bare minimum project to reproduce the error.

I've also tried upgrading to R3 2020

Cheers

In my Graph, I have set the AccessibleRole and AccessibleDescription. The alternative text is read correctly by the Acrobat Reader's 'Read out Loud' functionality.

The problem is that it keeps reading it multiple times.

In Chromium browsers such as Edge and Chrome, if I have set PDF files to always be downloaded from the browset content settings, and I click on the print button in the toolbar, the print dialog is never displayed, nor is the PDF downloaded.

Add support for print preview in the print dialog (Windows 11) of the desktop viewers. I am using the WPF viewer specifically. This preview appears for other print jobs—only when printing the Telerik report it does not.

Currently, graph axes do not provide a way to render separator lines between category groups. While this is generally not an issue for simple scenarios, it can make charts with nested categories difficult to read.

For example, when a graph displays multiple subcategories under a parent category (such as revenue ranges grouped by quarter), there is no built-in visual indicator showing where one parent category ends and the next begins.

It would be useful to provide support for category separators on graph axes, allowing report authors to visually separate category groups and improve readability when working with hierarchical data.

Currently, the LabelAngle property of a graph axis only affects the outermost category labels. For graphs with subcategories, there is no way to rotate the inner category labels independently. I would like to have control over the rotation of all category label levels, not just the outermost one.

It would be great if you could introduce the ability to create custom reusable color palettes in Telerik Report Designer, so I don't have to declare the same set of colors for each chart I need them.

If you have a lot of graphs in your report then it is more convenient to change the color palette one place.

Release 20.0.26.424

When using screen reader applications like JAWS or Narrator, those tools read accessible reporting PDFs in an incorrect order. For example, if I have two items in the report, the reader will read the second item first.

Additionally, images whose AccessibleDescription I have set may be read multiple times..

After an upgrade, I get an exception in my WinUI report viewer. Interestingly, if I continue through the exception, the report viewer does display but has an invalid license background. The invalid license seems to cause the exception.

Release 2026 Q2 (May)

When I display a report in a web report viewer, whose service is running on a server where one or more of the used fonts are not available, the first instance of the item(s) that use those fonts is being substituted with another font. The rest of the items do render with the original font, however.

This creates confusion and inconsistency. We should use the substituted font because it's used for measuring when using Print Preview mode in the web viewers, or when rendering to pdf via print/export.

Hi Team,

 

Even after giving the date format facing the inconsistency in the date field for some rows in the table when we export it to CSV file

<TextBox Width="1.036in" Height="0.24in" Left="0in" Top="0in" Value="= Fields.StartDate" Format="{0:MM'/'dd'/'yyyy h:mm tt}" Name="Opened Date">. please see the attachment

I have localized a report with a Graph in the 'ar-SA' culture.

When exporting to PDF from the viewer, the report is generated as expected. In the Report Viewer's Preview, though, the Graph Legend and Labels are not correct:

I am using Native Blazor Report Viewer, but the problem also reproduces in the HTML5-based web viewers, with all the themes I have tested.

We have spotted that PInvoke is now marked as deprecated (this applies even to the latest 0.7.124 version). In the description of the PInvoke.User32 NuGet package, it is mentioned that Microsoft.Windows.CsWin32 should be used instead:

Please consider replacing the deprecated package.

I am working with a static report (not using tables or groups), and I need to set the Level / TOC Level under the Interactivity section for an HTMLTextBox.
However, in my report, the Interactivity options do not show any property for Level. I am only seeing basic properties like Action, BookmarkId, DocumentMapText, TocText, etc.
The Level field is completely missing.

I am trying to use the line chart wizard; however, after selecting the data source, it seems to silently fail, as it does not display any fields, the "Next >" button is disabled, and no errors are displayed.

Dear Team,

Currently, the search functionality in the Report Viewer only matches the exact text as it is displayed on the screen. For example, if a value is formatted as "1,469", searching for "1469" yields no results.
Requested Change:
I would like the search functionality to work against the underlying data value. Users should be able to find numeric values even if they don't include the thousands separator (comma) or other formatting in their search query. This would make the report much more user-friendly and consistent with how users expect search to work.
Example:
  • Actual Value: 1469
  • Displayed Text: 1,469
  • Expected Search Behavior: Searching for "1469" should highlight "1,469".

Consider adding support for the `start` attribute of the `ol` element in HtmlTextBox. This would allow us to change the start counting:
