GridView - item remove from source collation not shown on Windows 11

60856927 46

I am using GridView to implement list of games with cover arts. All grid items are binded to ObservableCollection by ItemsSource="{x:Bind StoreInfo.GameInfos}"

I added an option to update the game cover art. To show updated item in live I remove the item from the ObservableCollection and add it back like following

var index = store.GameInfos.IndexOf(gameInfo);
store.GameInfos.Remove(gameInfo);
gameInfo.ImagePath = imagePath;
store.GameInfos.Insert(index, gameInfo);

On Windows 10 it works well but on Windows 11 it doesn't work - the item is not removed. User must refresh the page to see updated result. I don't want to add a logic to refresh entire page in case of Windows 11. Please help to find a solution to make it working on Windows 11 like it works on Windows 10.

It may be related to my Insider Windows 11 version. I tested on 2 PCs with Windows 11 and saw the same behavior. Later on one of PC this behavior disappeared but I changed nothing. Confusing.

If you’re working with WPF and using ObservableCollection<T>, the UI should automatically update when items are added or removed:

public ObservableCollection<GameInfo> GameInfos { get; set; } = new ObservableCollection<GameInfo>();
// Removing an item
GameInfos.Remove(gameInfo);
// Updating an item
gameInfo.ImagePath = imagePath;
// ObservableCollection automatically notifies the UI
GameInfos.Insert(index, gameInfo);

It seems to work in Windows 11. Show more details to reproduce the situation exactly. Maybe store and StoreInfo is not the same.

My case is UWP. I tagged it.

To help us further check the problem for you, could you please provide the win11 system version?
