Hi Antonio Roman,
Thank you for this report. We will need to further investigate the cause for this issue. However, I logged it in our PITS
where you can track it under the name "PanelBar: if the Orientation is Horizontal, an HtmlPlaceHolder cannot be displayed inside a RadPanelBarItem
" from tomorrow the latest.
I also updated your Telerik points accordingly.
Please accept our apology for the caused inconvenience.
All the best,
the Telerik team
