Each example is independent of the other - you can try just one. The sample code below can be added directly a 'File new project' MAUI app (with a name of 'MauiPlayground' to use the same namespaces), or it's all available from my demo code repo. The sample code is all below, but the fundamental question is whether this a bug somewhere in my code (do I need to 'tell' the controls to update themselves for some reason?) or possibly a bug in MAUI (in which case I should presumably report it)? Sample code Label and Checkbox) are visually updated, indicating that the view model notification is working fine and the UI itself is generally healthy.īuild environment: Visual Studio 2022 17.2.0 preview 2.1Īpp environment: Android, either emulator 'Pixel 5 - API 30' or a real Pixel 6 The problem I'm facing is that changes to the view model are not visually propagated to the Switch.IsToggled and ListView.SelectedItem properties, even though the controls do raise events showing that they've 'noticed' the property changes. I'm using 2-way data binding in my MAUI app: changes to the data can either come directly from the user, or from a background polling task that checks whether the canonical data has been changed elsewhere. ( CollectionView has similar issues, but other confounding factors that make it trickier to demonstrate.)

It's entirely possible that they're different problems that just share some common symptoms though. This question is about two MAUI controls ( Switch and ListView) - I'm asking about them both in the same question as I'm expecting the root cause of the problem to be the same for both controls.
