I am a bit nervous about your question, and why you want to do that.
First, do you understand why "... rowInfo[25] it throws an error."? While directly accessing the visual elements of a data-driven control is sometimes valid, it is more often due to a misunderstanding of the way those controls work. Now, if you set verticalScrollPosition = 25, then the row you want will be in the first renderer instance and you could probably figure out the location from that.
