  它被选中但你需要一个没有聚焦的高光

  <ListBox Grid.Row="0" x:Name="lbUtilities">
      <ListBox.ItemContainerStyle>
          <Style TargetType="ListBoxItem">
              <Style.Triggers>
                  <Trigger Property="IsSelected" Value="True" >
                      <Setter Property="FontWeight" Value="Bold" />
                      <Setter Property="Background" Value="Transparent" />
                      <Setter Property="Foreground" Value="Black" />
                  </Trigger>
              </Style.Triggers>
              <Style.Resources>
                  <SolidColorBrush x:Key="{x:Static SystemColors.HighlightTextBrushKey}" Color="Black"/>
                  <!-- Background of selected item when focussed -->
                  <SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="LightCyan"/>
                  <!-- Background of selected item when not focussed -->
                  <SolidColorBrush x:Key="{x:Static SystemColors.ControlBrushKey}" Color="LightGray" />
              </Style.Resources>
          </Style>
      </ListBox.ItemContainerStyle>
      <ListBoxItem Tag="2" Content="One" IsSelected="True"/>
      <ListBoxItem Tag="5" Content="Two" />
  </ListBox>

  <Grid FocusManager.FocusedElement="{Binding ElementName=lbUtilities}">
      <ListBox Name="lbUtilities" SelectedIndex="0" >
          <ListBoxItem Content="One"></ListBoxItem>
          <ListBoxItem Content="Two"></ListBoxItem>
      </ListBox>
  </Grid>

  我在listview控件中遇到了类似的问题，其中所选项目仅在用户点击它时突出显示，而不是从后面的代码突出显示，例如：

  MyListView.SelectedItem = SomeObjectInItemsSource
  

  我看到该项目已被有效选中但未按我的ItemContainerStyle中的定义突出显示 . 然后我尝试了别的东西：

  With CType(MyListView.ItemsSource,IList) 
      .MyListView.SelectedIndex = .IndexOf(SomeObjectInItemsSource)
  End With
  

  然后它开始按预期工作 .
