The VisibleItemCount property provides valuable insight into the total count of visible items within a given context. This count includes items that are currently visible on the screen as well as those that are not visible due to scrolling. By encompassing both visible and potentially hidden items, developers gain a comprehensive understanding of the complete item count, facilitating more informed decision-making and enhanced user experiences. The OversizeChanged event is triggered whenever there is a modification to the scroll range. The DefaultItemHeight property specifies the default item's height, in pixels.
