1 run demo 2 select tab "VirtualizableWrapPanel AllowDifferentSizedItems" 3 input number in the ScrollIntoView(Number) textbox, for example: 500 0r 800 4 you can find the listview can not scroll the 500 or 800 block position.

That's be design. If you need exact positioning and scrolling with different sized items you have to set the ItemSizeProvider property. This is shown in the "VirtualizableWrapPanel AllowDifferentSizedItems Lazy IItemSizeProvider" tab.
