How can I update a collection in Xamarin.Forms?

How can I update a collection in Xamarin.Forms?

You can update a collection in Xamarin.Forms by using ObservableCollection, which automatically updates the UI when items are added or removed.

Can you show me an example of using ObservableCollection?

Sure! Here's a simple example:

ObservableCollection<string> items = new ObservableCollection<string>();
items.Add("Item 1");
items.Remove("Item 1");

This will update the UI automatically when you modify the 'items' collection.

What if I want to sort the collection?

You can sort the collection by creating a new sorted list and then updating the ObservableCollection. For example:

var sortedItems = items.OrderBy(x => x).ToList();
items.Clear();
foreach (var item in sortedItems) items.Add(item);
