列表框从usercontrol中选择的项目

Question

我有一个带有控件的列表框，控件中填充了文本框和组合框。当我编辑文本框并在组合中选择时，我需要选择基础列表项。似乎无法找到解决方案。任何人吗？

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

您可以添加EventTrigger，以便在其中一个控件聚焦时选择基础ListBoxItem。像这样：

<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>
