On the server side, you can use ScrollY property. You will be able to calculate the resource Y if you know how many overlapping events are there in every row. If it's just one, it's not that hard.
In other cases, you can call scrollToResource(id) on the client side. It will find the resource by its id and scroll it to the top.
It was introduced in 7.1 release:
