Class ResetScrollBehavior

Namespace

McServerLauncher.Behaviors

Assembly

McServerLauncher.dll

Attached property that sends a list back to the top when its contents are replaced, and leaves it alone when items are merely appended.

The distinction is the point. Changing a filter or the search produces a *different* set of results, where the position the user was at means nothing — the twentieth optimisation mod has no relation to the twentieth magic mod — so the list starts at the top. "Load more" produces the *same* set with more at the end, so the position must survive; anything else would throw the user back to the start of a list they were halfway through reading.

The view model already draws that line: it swaps the collection in one go (a Reset) for a new set and appends (an Add) for more of the same. This just follows it, which is why no extra state is needed on either side.
