I’ve used the implementation of lazy load seen in https://vaadin.com/docs/v14/flow/binding-data/tutorial-flow-data-provider.html. The problem is that I don’t know how many items the grid is going to have, and calculating that number takes a lot of time.
So, is it possible to have a grid add items as the user scrolls and as long as the backend service has more items.
I have no answer, but did you noticed this blog: https://vaadin.com/blog/request-for-comments-lazy-data-binding-improvements. Maybe this blog is useful.
Nicolas, with lazy loading, you will need to know the total count. The lazy loading mechanism wont work correctly if you don’t.
