it is correct that when I am scrolling, all items should be loaded, but my case is another.
The LoadSize of VirtualQueryableCollectionView is 100. The database contains 5000 items.
When I select any item in the first 100 loaded items, all is fine. When I jump to any area in GridView, for example to the last item (CTRL+End Key), the GridView loads the displayed range of items (items from index 4900-5000), that's correct. If I try to select for example the last item (without pressing the SHIFT-Key), all items from index 0 up to the selected index (the last one, 5000) are loaded, although I don't need them, because this should behave like the SelectionMode.Single. All this items should only be loaded, if I really press the SHIFT-Key, because only in this case I need all the items. This problem is the same, if I jump to any area in the GridView by dragging the Scrollbar with the mouse, for example to the item at index 2500.
