Hi Jakub Olichwier ,
We have reviewed your query, and based on the information you provided, we have prepared a sample using the Record Template View. In the template, we have used a TextBlock and a Button, and upon expanding the parent row, the scrollbar appeared. We performed scrolling using the mouse wheel, and the scrolling functioned as expected and the scrollbar was appeared.
To proceed further,
1.Could you kindly provide more details about the elements inside the Record View Template?
2. Are you applying any themes for the SfDataGrid, and have you implemented any customizations for scrollbars?
We have provided a sample for your reference. Please review the sample, and if possible, modify it to replicate your scenario. This will help us assist you more effectively.
We appreciate your understanding and patience.
Regards,
Sweatha.B
