列表框从用户控件中选择了项目

我有一个填充有控件的列表框，该控件填充有文本框和组合框。当我编辑文本框并在组合中选择时，我需要选择底层列表项。似乎找不到解决方案。有人吗？

    <ListBox.ItemTemplate>
        <DataTemplate>
            <Controls:ComponentEditItem Background="Transparent"/>
        </DataTemplate>
    </ListBox.ItemTemplate>

您可以添加一个 EventTrigger，当其中一个控件获得焦点时，它会选择底层的 ListBoxItem。像这样的东西：

<ListBox.ItemTemplate>
    <DataTemplate>
        <Controls:ComponentEditItem Background="Transparent">
             <Controls:ComponentEditItem.Triggers>
                  <EventTrigger RoutedEvent="GotFocus">
                        <BeginStoryboard>
                            <Storyboard>
                                 <BooleanAnimationUsingKeyFrames Duration="00:00:00" Storyboard.Target="{Binding Path=., RelativeSource={RelativeSource FindAncestor, AncestorType=ListBoxItem}}" Storyboard.TargetProperty="IsSelected">
                                      <DiscreteBooleanKeyFrame Value="True" />
                                 </BooleanAnimationUsingKeyFrames>
                             </Storyboard>
                        </BeginStoryboard>
                   </EventTrigger>
             </Controls:ComponentEditItem.Triggers>
       </Controls:ComponentEditItem>
    </DataTemplate>
</ListBox.ItemTemplate>

You can add an EventTrigger that selects underlying ListBoxItem when one of its controls is focused. Something like this:

<ListBox.ItemTemplate>
    <DataTemplate>
        <Controls:ComponentEditItem Background="Transparent">
             <Controls:ComponentEditItem.Triggers>
                  <EventTrigger RoutedEvent="GotFocus">
                        <BeginStoryboard>
                            <Storyboard>
                                 <BooleanAnimationUsingKeyFrames Duration="00:00:00" Storyboard.Target="{Binding Path=., RelativeSource={RelativeSource FindAncestor, AncestorType=ListBoxItem}}" Storyboard.TargetProperty="IsSelected">
                                      <DiscreteBooleanKeyFrame Value="True" />
                                 </BooleanAnimationUsingKeyFrames>
                             </Storyboard>
                        </BeginStoryboard>
                   </EventTrigger>
             </Controls:ComponentEditItem.Triggers>
       </Controls:ComponentEditItem>
    </DataTemplate>
</ListBox.ItemTemplate>
