Thanks for writing.
Based on the source code you are pasting we cannot exactly say what happens. The VirtualizingDataCollection
simply tracks which scroll position are you at and requests that all visible items are initialized for that scroll position. If your visual items are small enough that they all fit in the DataBoundListBox'
'viewport - they will all be loaded at once in the beginning and you will not receive any further ItemsLoading
Anyway, if you share with us your project in a separate support ticket we will be able to inspect your code and see how we can further assist you.
