Is there a way to dispose ViewModels created by BindKeyedList?

[marklam]

I've got a ViewModel with a BindKeyedList creating ViewModels for the items of a list, so like

type TopViewModel() =
    inherit ReactiveElmishViewModel()

    member this.ListItems =
            this.BindKeyedList(store, getItems, map = fun item -> new SubViewModel(item), getKey = fun stcvm -> stcvm.Name)

When the TopViewModel is disposed, is there a way to have the items in ListItems disposed too?

I think you should be able to add them to the disposables list on your VM:

ReactiveElmish.Avalonia/src/ReactiveElmish/ReactiveElmishViewModel.fs

Line 413 in 4320bc9

member this.AddDisposable(disposable: IDisposable) =

For example:

type ActionVM(action: Action) =
    inherit ReactiveElmishViewModel()
    
    member this.Timestamp = action.Timestamp
    member this.Description = action.Description

    interface IDisposable with
        member this.Dispose() = printfn "Disposing ActionVM"

type CounterViewModel() as this =
    inherit ReactiveElmishViewModel()

    let local = 
        Program.mkAvaloniaSimple init update
        |> Program.mkStore

    let mkActionVM action = 
        let vm = new ActionVM(action)
        this.AddDisposable(vm)
        vm

    member this.Count = this.Bind(local, _.Count)
    member this.Actions = 
        this.BindList(
        local
        , _.Actions 
        , map = mkActionVM 
        , sortBy = _.Timestamp
    )
    member this.Increment() = local.Dispatch Increment
    member this.Decrement() = local.Dispatch Decrement
    member this.Reset() = local.Dispatch Reset
    member this.IsResetEnabled = this.Bind(local, fun m -> m.Actions.Length > 1)

    static member DesignVM = 
        new CounterViewModel()

Many thanks for that!.
That approach works nicely.
