Additional information and Workflow

Can't reproduce, come from here: https://github.com/sn4k3/UVtools/issues/554

Probably a dup https://github.com/AvaloniaUI/Avalonia/issues/7467

sn4k3 commented 2 years ago

Probably a dup #7467

Looks the same trouble. I can't reproduce :(

joedemax commented 1 year ago

I am also facing this bug. To reproduce, create a ComboBox and set it's ItemSource in code to an ObservableCollection. Then, update your collection from another thread (a timer will do). As soon as it tries to update you'll get this exception.

timunie commented 1 year ago

@joedemax use Dispatcher.UiThread.Post to update a collection from another thread. Otherwise it's not allowed.

joedemax commented 1 year ago

Tim,

Thank you for your quick response. That worked just fine. Is there any other collection suitable for this that works similar to BindingList in WinForms where threading is automatically handled?

Joe

Hi Joe,

I personally use this: https://www.reactiveui.net/docs/handbook/collections/. It's a bit complex to learn it in the first step, but after that it works great. You still need to raise the events on the UIThread.

Was fixed after items presenter refactoring
