Question

我目前正在使用click事件在UserControl中保存文件数据（通过后台工作程序），在每个步骤中更新主窗口中的控件，该控件运行良好并从UserControl获取更新。代码如下。

更新：我应该声明我使用的是FirstFloor MUI框架和主窗口中的mui：ModernTab。

MainWindow.xaml控件（控件在更新发生前隐藏）（使用x：FieldModifier =＆＃34; public＆＃34;）

<StatusBar x:Name="mainStatus" Height="24" VerticalAlignment="Bottom" Panel.ZIndex="999999" BorderThickness="0,1,0,0" BorderBrush="#FFBDBDBD" Background="Transparent" Margin="0,0,0,-15">
        <StackPanel x:Name="global_message" Height="28" Width="718" x:FieldModifier="public" Margin="0,4,0,0" Visibility="Hidden">
            <fa:ImageAwesome x:Name="global_message_block_icon" x:FieldModifier="public" Height="12" Width="15" HorizontalAlignment="Left" Visibility="Hidden" >
                <fa:ImageAwesome.Foreground>
                    <SolidColorBrush Color="{DynamicResource AccentColor}"/>
                </fa:ImageAwesome.Foreground>
            </fa:ImageAwesome>
            <TextBlock x:Name="global_message_block" x:FieldModifier="public" Margin="19,-13,0,0" HorizontalAlignment="Left" Height="15" Width="850" FontSize="12" FontWeight="Bold" Visibility="Hidden" >
                <TextBlock.Foreground>
                    <SolidColorBrush Color="{DynamicResource AccentColor}"/>
                </TextBlock.Foreground>
            </TextBlock>
        </StackPanel>
    </StatusBar>

用于更新MainWindow +中所选控件的UserControl（MyControlA.xaml.cs）代码可能更新另一个UserControl中的另一个控件（ProcessTools / PODDuplicate.xaml）

//Works well
foreach (System.Windows.Window window in System.Windows.Application.Current.Windows)
  {
     if (window.GetType() == typeof(MainWindow))
        {
          (window as MainWindow).global_message.Visibility = Visibility.Hidden;
          (window as MainWindow).global_message_block.Text = "";
          (window as MainWindow).global_message_block.ToolTip = "";

         }
 }

 //Code to access ProcessTools.PODDuplicate(ProcessTools/PODDuplicate.xaml) which has the control I wish to change/update
 foreach (UserControl usercontrol in System.Windows.Application.Current.Windows)
         {
             if (usercontrol.GetType() == typeof(UserControl))
             {
                 (usercontrol as ProcessTools.PODDuplicate).form_process_pod.Visibility = Visibility.Hidden;

             }

   }

问题在于;

foreach (UserControl usercontrol in System.Windows.Application.Current.Windows)

永远不会起作用，因为需要更新的对象是控件而不是窗口类型。

是否可以访问＆＃34;其他UserControl＆＃34;并更新控件设置？

更新另一个UserControl C＃WPF中的控件
