Question

我正在开发一个只运行多个后台进程，无用户交互的UI;只是直观地显示进程正在做什么。逻辑/用户界面层次结构为：

+ one Shell UI, with list view of (many):
\---+ BackgroundProcess container(s), each of which is composed of:
    \---+ a. Info about FIRST Half of BackgroundProcess instance, namely:
    |   \---+ Current State
    |   \---+ ErrorInLogFile?
    |   \---+ ProgressBar      
    \---+ b. Info about SECOND Half of BackgroundProcess instance, namely:
        \---+ Current State
        \---+ ErrorInLogFile?
        \---+ ProgressBar

关注我有一个用户控件列表这一事实，每个用户控件都由两个用户控件组成。我的问题是对Current State的更新，isErrorInLogFile和Progress未显示，对我来说，不知何故我构建我的xaml的方式不足以让Caliburn激活第二级用户 - 控件。

文件FullAppCard中的后台进程容器名为FullAppCard.xaml，具有以下ViewModel类签名：

public class FullAppCardViewModel : PropertyChangedBase { ... }

//FullAppCard.xaml:
<UserControl x:Class="DocuFaxbackUI.Views.FullAppCardView"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
             xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
             xmlns:local="clr-namespace:DocuFaxbackUI.Views"
             mc:Ignorable="d">
    <Grid>
        <Grid.RowDefinitions>
            ...
        </Grid.RowDefinitions>
        <local:AppCardView x:Name="Part1" />
        <local:AppCardView x:Name="Part2" />
    </Grid>
</UserControl>

和AppCardView，与整个过程的第一个和第二个“半”有关：

public class AppCardViewModel : PropertyChangedBase { ... }

<UserControl x:Class="DocuFaxbackUI.Views.AppCardView"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
             xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
             xmlns:cal="http://www.caliburnproject.org"
             mc:Ignorable="d">
    <Grid HorizontalAlignment="Stretch">
        <Grid.ColumnDefinitions>
            ...
        </Grid.ColumnDefinitions>
        <Grid.RowDefinitions>
           ...
        </Grid.RowDefinitions>
        <TextBlock Name="Status"/>
        <Label Name="Error" cal:Message.Attach="[Event MouseUp] = [Action OpenLogFile];"/>
        <ProgressBar Value="{Binding Path=CurrentProgress}" Maximum="{Binding Path=MaximumProgress}" />
    </Grid>
</UserControl>

执行FullAppCardViewModel列表的ShellViewModel继承自Conductor<PropertyChangedBase>.Collection.AllActive。尽管有这样的设置，似乎我仍然无法在AppCardView中进行更改以注册ShellViewModel级别的UI编组线程。

Shell的Child's Child元素未在Caliburn Micro中更新
