UI-TOOLKIT MultiColumnListView scroll event

I’d like to show some customized assets info with MultiColumnListView( multi column to show asset info like name updater creator categories etc.) .
First, I loaded first 100 assets from server.
I want to load next 100 asset infos when I received the list scrolled near bottom.
How can I receive any event to deal with it? or can I use other element to do this ?
Please help me , thanks!

The MultiColumnListView in Unity is designed to handle data by only requesting the values for currently visible items. You don’t need to load all data immediately or monitor scrolling events manually. Instead, the ListView manages data requests dynamically.

When using the bind event, it fetches data for items as they become visible. Simply provide the ListView with the total number of items, and it will handle data requests as users scroll.

For an example see here : Unity Documentation - ListView and TreeView.

If your data resides on a server, you can initially use placeholders in your list. As items become visible, fetch the data from the server and populate the placeholders.

We have a guide in the docs here Unity - Manual: MultiColumnListView

In Unity 6 we also added the MultiColumnListView in the UI Builder library so it can be setup and configured via UXML.
