Hi Stoyan,

I do understand that this could be inconvenient for some scenarios, but the virtual scrolling is not suitable for scenarios where the data will change dynamically. If the number of item changes, the Grid will reset its scroll position, because it will render a new virtual scrollbar and the old position will not be relevant anymore. Please note that the "virtual" scrollbar height is set based on the total number of items and when that changes, it creates a new scrollbar and in order to avoid any issues with the new data, it resets the scroll position. The same behavior is observed if you filter the Grid with enabled virtual scrolling.

Nevertheless, if you want to keep the scroll position, you can store the scrollTop value and the original skip value and re-apply them after changing the data:

Hello Stoyan,

Thank you for providing an example demonstrating the problem.

We will have to discuss this scenario within the team to see if changing the total value dynamically should fire the onPageChange event, since the scroll position is reset. Nevertheless, with the current implementation you can manually reset the "skip" value to "0" when you change the data count:
