Hi Telerik Team,

We are experiencing an issue related to tooltips in PDF exports from Telerik Reporting.
When we enable tooltips using the ViewerRenderToolTips setting both at the report level and through the device info in the report service, tooltips are appearing in the exported PDF—but they are being rendered as text annotations, not as normal tooltips.

Issue:
In the resulting PDF, tooltips are rendered as Text Annotations, which:

1.Appear as popups or sticky notes on mouse hover/click
2.Are not the standard tooltip experience expected by users
3.May affect accessibility compliance and user readability

Expected Behavior:
Tooltips should appear as standard PDF tooltips (like browser-style hover text) instead of annotations.

Attachments:
Sample Telerik Report (.trdp)
Generated PDF output showing the issue

Please advise if this is expected behavior or a bug, and whether there's a way to control the tooltip rendering to match typical PDF tooltip behavior (or to make them more accessible).

Thanks,
Pramod

Release 2025 Q4

We use WPF Report Viewer in our application. For testing, validation, and automation purposes, we need to:

  • Uniquely identify each element in the XAML rendered report contents to support automation.
  • Prevent the element ID changes. The generated item IDs must remain consistent as long as the report definition is not changed.

While customising templates/CSS, I noticed the .trv-parameters-wrapper div as follows:

<div tabindex="300" class="trv-parameters-wrapper" aria-label="Parameters area. Contains 4 parameters.">
<div class="trv-parameter-container k-card"></div>
</div>
The report being tested had 1 visible and 3 invisible parameters and one .trv-parameter-container is rendered. Counting 4 being contained in the "Parameters area" does not appear to be too helpful.

I have 2 Date parameters on my report. The "Start Date" parameter defaults to today, and the "End Date" defaults to the "Start Date" + 1 Year.

This works fine in the Report Designer, e.g., when the Start Date is changed in preview mode, the End Date value is recalculated.

However, this behavior does not work in the Blazor Native Report Viewer.  When the page first renders, the two dates are shown correctly, but if the Start Date is changed, the End Date is not recalculated.

Currently, the VS item templates, and the documentation suggest using app.UseEndpoints for route registration in ASP.NET Core.

It would be better to use top-level route registrations like app.MapControllers() and app.MapControllerRoute() directly.

I am using the TypeValidator class' method to dynamically allow assemblies/types to be used by the reporting engine, but it does not work in the context of a custom IReportSourceResolver(Reporting REST Service).

When using the "Close"/"Close All" options when a report has unsaved modifcations, a warning is shown, but you are forced to save the report or close the window/tab to leave definition file unmodified.

A "close and discard changes" option is helpful and convenient - one can cancel some edits without hoping that a bunch of "Ctrl - Z" presses will clear everything, refer to one report without concern about accidental modifcations (can be editing others), etc.

I use the font Roboto in a TextBox rotated vertically. The last character of the content is cut in the design time of the Standalone Report Designer. In Preview and when exporting to PDF, the content is displayed as expected.

I’m using Telerik.Reporting v19.1.25.521 to generate PDF files. After upgrading the Telerik.Licensing NuGet package to version 1.6.16, all SVG files stopped rendering in the output.

Reverting back to the previous version resolves the issue. I also tested the latest available version (1.6.21), but the problem still persists.

I am currently working on adapting our documents to meet EAA accessibility requirements, and I have upgraded Telerik Reporting to version 19.2.25.813.

I added { "EnableAccessibility", true } to the device information settings when exporting to PDF.

However, when I run the generated PDF through the PAC accessibility checker, it reports the following error:

One or more checks could not be completed.

Please copy the error message and send it by email to pac@axes4.com so that we can improve the product.

When importing a report with the Standalone Report Designer for .NET, if the report or its items use report events, they are not automatically imported into the TRDP file.

It is currently necessary to manually type the method names in the corresponding properties in the report designer.

I have cascade parameters that depend on other parameters (check the Product Line Sales report for an example). I have set these parameters with `autoRefresh` of `false`. In the Standalone Report Designer, once I change the value of a parameter, the dependent parameter also changes automatically. However, this is not the case in the Native Angular report viewer.

I have a string parameter with `autoRefresh` set to `true`. In the report viewer, it displays a textbox as a parameter editor. However, the report viewer refreshes on every "keydown" event, which can be frustrating for users. In the Standalone Report Designer, the report is refreshed only after the textbox is unfocused.

I would like for there to be a feature in the report designers, where when I use the SqlDataSource component, the designer automatically picks up what fields I am using in the report, and edits the SQL query's SELECT statement to include only those fields.

To clarify our usage scenario: we design reports directly against SQL tables, stored procedures, or views from the start. The report definition is dynamic and often driven by user input, so we rely heavily on runtime evaluation. In our current reporting system, the optimization happens automatically during execution: The engine inspects the report layout and selection formulas, then generates SQL that includes only the fields actually used. This means the designer doesn’t need to manually prune unused fields — the runtime engine handles it intelligently.

In Telerik Reporting, we envision a similar behavior: once the report definition is finalized (whether in the designer or programmatically), the engine could analyze which fields are referenced in expressions, filters, groupings, visibility conditions, etc., and optimize the data retrieval accordingly. This would be especially beneficial for stored procedures or views with wide schemas, where only a subset of fields are relevant to the report logic.

In the latest version (19.2.25.924), adding assembly references for assemblies with no public key raised the error "Object reference not set to an instance of an object", and the designer restarts. This error then occurs every time I open the designer, with Options => Assembly References no longer visible.

WebReportDesigner (Blazor) - permission to restrict "Build new data connections" and allow to use only "Select from existing data connections".

It isn't required, but would be nice have button "Test connection" in the bottom enabled to verify predefined connection
