How to bring the item into view when adding at runtime in the listview?
1 min read
ListView allows you scroll to the end using the ScrollToRowIndex or ScrollTo method when the items are added into the collection using the DisplayItemCollectionChanged event.
If you have header or groupheader, then consider the index and give it to the ScrollToRowIndex method.
C#
listView.DataSource.DisplayItems.CollectionChanged += DisplayItems_CollectionChanged;
private async void DisplayItems_CollectionChanged(object sender, System.Collections.Specialized.NotifyCollectionChangedEventArgs e)
{
if (e.Action == System.Collections.Specialized.NotifyCollectionChangedAction.Add)
{
await Task.Delay(100);
var item = e.NewItems[0];
var itemIndex = listView.DataSource.DisplayItems.IndexOf(item);
(listView.LayoutManager as LinearLayout).ScrollToRowIndex(itemIndex, true);
}
}
