Tooltip Showing as Normal Tooltip Instead of Text Annotation in Telerik PDF Export

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

Hi Pramod,

Thank you for the attached documents and the additional information!

Indeed, the PDF rendering extension currently renders the tooltips in the exported document as text annotations. The reason for the tooltips to be rendered as such is that during our research for the PDF version 1.6 format, this seemed to be the standard way to render tooltips in PDF 1.6 documents.

With that being said, our team will further investigate if that is the case, and whether that has changed in newer versions of the PDF file, and we will update this item when we have more information to share. For the time being, the status of the item will be set to "Under Review".

Thank you for your understanding!

Regards,
Dimitar
