Hello,
I was not able to reproduce the same issue on my end.
I made a Grid which is higher than the page and it does not scroll to the top of the page when a button is clicked:
http://dojo.telerik.com/OCemU
I can assume that based on a custom logic, the Grid may be re-rendered on a button click and the scroll position is reset.
Please check the following article demonstrating how to resolve this:
http://docs.telerik.com/kendo-ui/controls/data-management/grid/appearance#restore-scroll-positions
If my assumption is not correct please send a fully runnable example reproducing the issue and I will gladly assist.
Regards,
Stefan
