DataGrid does not display all rows

[samyraj19]

Describe the bug

DataGrid displays only 91 out of 100 rows and cannot scroll further. Even with a

correct Grid layout and virtualization disabled, the remaining rows are not visible.
Scrolling stops unexpectedly, and the remaining rows are never rendered or reachable.

Run the application and scroll the DataGrid in the UI.
