Xamarin CollectionView Current Group

Question

How to get current visible group name in CollectionView when scrolling? I want to show this info in page title.

myCollectionView.Scrolled += (object sender, ItemsViewScrolledEventArgs e) =>
{
    int first_index = e.FirstVisibleItemIndex;
};

Answer 1

You could get the index and then get the matched item to get the group name.

   int first_index = e.FirstVisibleItemIndex;
        if (first_index!=0)
        {
            Name = ObservCollectionCategory[first_index-1].Category_Name;
            //The ObservCollectionCategory is the item source of Collectionview.
        }

And then binding the name of the title.

Title="{Binding Name}"
