Incremental ListView Control and Plugin for Xamarin.Forms

Hi there 👋

incrementallistview's Issues

Nothing appears on my xamarin.forms app

Can you give me a help on the ListView implementation?

I followed your code but my app is displaying nothing.

Refresh on iOS

Your plugin is great but I need to implement a "Refresh" feature and I am facing problems on iOS.

Maybe because the loading logic is initianalised in the "OnAppearing" event of the ContentPage, when I refresh the list, even if the "HasMoreItems" property has a value of "True", only the first "page" items are in the list.

There is no issue on Android.

ISupportIncrementalLoading unavailable to PCLs through nuget

I have my viewmodels in a PCL which is where I would like to keep the collections that would be used for incremental loading. At the moment, the nuget package is only for a pure xamarin forms project which means my PCL has no access to the interface.

Grouped listview

Sorry, currently not a reproducable poc available.
But it seems that if we have a grouped list that will fetch items with LoadMoreItems, we sometimes don't trigger the get more method.

If there are groups that are mixed with x amount of items lager and lesser than the preloadcount, we are able to scroll past that count and hit the bottom of the list, even if there should be new items loaded.
BUT scrolling back up to top, reach a group with enough items, the load more is again retriggerd.

Hard to pin point the exact root cause, guessing the count of item source is the culprit here.
