wpf에서 코드 뒤에 Listbox 컨트롤을 얻는 방법

Question

ListBox 컨트롤을 코드 뒤에 넣으려고합니다. 다음 코드는 내가 쓴 : 목록 상자 항목의 내용을 변경하는

<ListBox x:Name="listbox" Grid.Column="0" SelectedIndex="0" BorderThickness="0" Style="{StaticResource myListboxStyle}" ScrollViewer.HorizontalScrollBarVisibility="Disabled" ScrollViewer.VerticalScrollBarVisibility="Hidden" ItemsSource="{Binding IsAsync=True}" DataContext="{Binding IsAsync=True}" ItemStringFormat="{Binding IsAsync=True}" BorderBrush="Black" IsEnabled="True"> 

<ListBox.ItemTemplate> 
    <DataTemplate> 
     <Grid x:Name="gridEmployee" Height="90" Margin="1,0,0,1"> 
      <Grid.ColumnDefinitions> 
       <ColumnDefinition Width="80" /> 
       <ColumnDefinition Width="*" /> 
       <ColumnDefinition Width="25" /> 
      </Grid.ColumnDefinitions> 

     <Grid x:Name="pic" HorizontalAlignment="Center" VerticalAlignment="Center" Margin="8,8,0,8"> 
      <Border Name="mask" CornerRadius="7" removed="White" /> 

      <Image x:Name="imgEmp" Height="50" Width="50" Stretch="Fill"> 
       <Image.OpacityMask> 
        <VisualBrush Visual="{Binding ElementName=mask}"/> 
       </Image.OpacityMask> 

       <Image.Style> 
        <Style TargetType="{x:Type Image}"> 
         <Setter Property="Source" Value="{Binding Path=PicPhoto, IsAsync=True}"></Setter> 
         <Style.Triggers> 
          <DataTrigger Binding="{Binding Path=PicPhoto, IsAsync=True}" Value="{x:Null}"> 
           <Setter Property="Source" Value="/TimeAttendance_PageTransition;component/Images/blank.jpg" /> 
          </DataTrigger> 
         </Style.Triggers> 
        </Style> 
       </Image.Style> 
      </Image> 
     </Grid> 

     <StackPanel Name="spEmpData" Margin="5,6,0,0" Width="206" Grid.Column="1"> 
      <TextBlock Name="tbEmpName" TextBlock.FontWeight="Bold" Text="{Binding Path=Staff_Name_e, IsAsync=True}" Margin="0,6,0,0" FontSize="22" FontFamily="Browallia New"> 
       <TextBlock.Effect> 
        <DropShadowEffect Color="White" BlurRadius="2" Direction="280" ShadowDepth="2"/> 
       </TextBlock.Effect> 
      </TextBlock> 

      <TextBlock Name="tbPunchDate" Text="{Binding Path=Punch_Date, IsAsync=True}" Margin="0,0,0,0" FontSize="13" Foreground="#FF545454"> 

       <TextBlock.Effect> 
        <DropShadowEffect Color="White" BlurRadius="2" Direction="280" ShadowDepth="2"/> 
       </TextBlock.Effect> 
      </TextBlock> 

      <TextBlock Name="tbEmpCode" Text="{Binding Path=Emp_Code, IsAsync=True}" Margin="0,3,0,0" FontSize="13" Foreground="#FF545454"> 

       <TextBlock.Effect> 
        <DropShadowEffect Color="White" BlurRadius="2" Direction="280" ShadowDepth="2"/> 
       </TextBlock.Effect> 
      </TextBlock> 
    </StackPanel> 

    <Canvas Grid.Column="2"> 
     <Ellipse Margin="0,11,0,0" Height="18" Width="18" Opacity="1" VerticalAlignment="Top" HorizontalAlignment="Center" d:LayoutOverrides="Width"> 
      <Ellipse.Fill> 
       <LinearGradientBrush EndPoint="0.0,0.1" StartPoint="0.0,0.0"> 
        <GradientStop Color="{Binding Path=Function_Key, IsAsync=True}" Offset="1"/> 
       </LinearGradientBrush> 
      </Ellipse.Fill> 
     </Ellipse>  
    </Canvas> 
</Grid> 

    <DataTemplate.Triggers> 
     <DataTrigger Binding="{Binding RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type ListBoxItem}},Path=IsSelected}" Value="True"> 
       <Setter TargetName="tbEmpName" Property="Foreground" Value="Black"/> 
       <Setter TargetName="tbEmpCode" Property="Foreground" Value="Black"/> 
       <Setter TargetName="tbPunchDate" Property="Foreground" Value="Black"/> 
       <Setter TargetName="gridEmployee" Property="Background"> 

       <Setter.Value> 
        <LinearGradientBrush EndPoint="0,1" StartPoint="0,0"> 
         <GradientStop Color="{DynamicResource {x:Static SystemColors.GradientActiveCaptionColorKey}}" Offset="0"/> 
        </LinearGradientBrush> 
       </Setter.Value> 
      </Setter> 
     </DataTrigger> 
    </DataTemplate.Triggers> 
    </DataTemplate> 
</ListBox.ItemTemplate> 

    <ListBox.ItemsPanel> 
     <ItemsPanelTemplate> 
      <WrapPanel Orientation="Horizontal"/> 
     </ItemsPanelTemplate> 
    </ListBox.ItemsPanel> 
</ListBox> 

이것은 ListBox, 나는 뒤에 코드에서 ListBox 내부 통제를 원하는 내된다. 코드 뒤에서 ListBox 컨트롤 ('목록 상자')을 얻었지만 Image ('imgEmp') & 텍스트 블록이 코드 숨김으로 표시되지 않았습니다.

필자는 분명히 VB에서 컨트롤 배열과 같은 목록 상자 항목을 제어하려고합니다. 어떻게해야합니까?

미리 감사드립니다.
