Csharp 子组件：如何根据另一个组件的状态启用输入

我正在开发Blazor WebAssembly应用程序，其中我有一个包含两个子组件(Child1和Child2)的父组件Father.只有在满足Child 1中的特定条件时才应启用Child2，但我在维护这些组件之间的正确状态时遇到了问题.

在Child1中，我有一个自动完成组件MudAutocomplete，在 Select 后，它应该通过在父组件Father中设置状态Model.SuperUser来启用Child2中的某些功能.我已经确保在更新Child1中的状态后调用StateHasChanged()，但即使满足条件Model.SuperUser != null，Child2中的输入也保持禁用状态.

@page "/father"

<Child1 Model="model" />
<Child2 Model="model" />

@code {

    private MyModel model;
    protected override void OnInitialized()
    {
        model = new MyModel();
        base.OnInitialized();
    }


    public class MyModel
    {
        public int? AdminUserId { get; set; }
        public UserDTO? AdminUser { get; set; }

        public int? CustomerUserId { get; set; }
        public UserDTO? CustomerUser { get; set; }

        public int? SuperUserId { get; set; }
        public UserDTO? SuperUser { get; set; }
    }
}

// Child1.razor
<!-- SuperUser -->
<div class="form-group col-6">
    <label class="required" for="SuperUser">@Localizer["SuperUser"]</label>
    <MudAutocomplete T="UserDTO"

@code {
    [Parameter][EditorRequired] public MyModel Model { get; set; } = null!;

    private async Task<IEnumerable<UserDTO>> SearchAdminUser(string value)
    {
        if (Model.SuperUserId.HasValue && Model.SuperUserId.Value > 0)
        {
            var filter = new { Model.SuperUserId, value };
            var result = await _myService.GetAdminUserBySuperUserFiltered(filter);
            if (result != null)
            {
                return result;
            }
        }
        return new List<UserDTO>();

    }

    private void OnAdminUserCleared(MouseEventArgs args)
    {
        Model.AdminUser = null;
        Model.AdminUserId = null;
        StateHasChanged();
    }

    private void OnAdminUserValueChanged(UserDTO value)
    {
        Model.AdminUser = value;
        Model.AdminUserId = value.Id;
        StateHasChanged();
    }
}

尽管在Child1中正确更新了Model.SuperUser并调用了StateHasChanged()，但Child2中的Disabled="Model.SuperUser == null"条件并未如预期那样启用输入.

关于如何根据Model.SuperUser从Child1的状态正确启用/禁用Child2中的输入有任何建议吗？
