Greetings from syncfusion support
Based on your query we have checked our virtual scrolling sample in our demos and tried to reproducing the issue but it works fine from our end. When clicking on the bottom row in the table container the selected row is not repositioned in the center. Please refer the below video demo for more information.
If you still face the issue, please share the below details that will be helpful for us to provide better solution.
1) Please share your syncfusion package version.
2) Please share your issue scenario in video demonstration format.
3) Please share your complete Grid rendering code.
4) Please confirm have you rendered the Grid inside any of the component.
Regards,
Rajapandi R
