This does not happen on Android.
RadListView is in a star-sized grid row. In the same grid, there is an auto-sized row that contains a control who's height changes as the user interacts with the view. The RadListView uses an item template selector, and items have different heights.
When the auto-sized row changes height, the star-sized row, which contains the RadListView, changes height. When this occurs, the items that were visible in the RadListView scroll out of view. The distance that the RadListView scrolls seems to increase the farther down the list the control is. It seems that the grid is redrawing itself completely and is trying to maintain the scroll position but is calculating the position incorrectly -- maybe using some default item height instead of the actuall scroll position in pixels.
