Hi Ahmed,
Thanks for contacting Syncfusion support.
To set the `rowRenderingMode` property as `Vertical`, we need to add the `e-bigger` class to the parent container of the EJ2 grid which is the default behavior. Please refer to the below sample link for more information.
If you are still facing the issue, please share the below details that will be helpful for us to provided you a better solution as early as possible.
- Do you want to show rows horizontally as in your screenshot in windows and vertical in devices?
- Share the before upgrading screenshot if possible
- Share your previous EJ2 version.
Regards,
Pavithra S
