绑定到列表框，但只显示所选元素? [英] Bind to a listbox, but only show the selected element?

问题描述

我有一个绑定到 ListBox 的对象集合，但实际上我只想显示所选元素，而不是整个集合.解决这个问题的最佳方法是什么?使用不同的控件?

I have a collection of objects which I bind to a ListBox, but I actually only want to display the selected element, and not the entire collection. What's the best way to go about this? Use a different control?

我想我可以做一个 Visibility ValueConverter 来检查 IsSelected 属性——如果没有被选中会崩溃……但我仍然对其他想法感兴趣.

I think I can do a Visibility ValueConverter which checks the IsSelected attribute -- and if not selected collapses... but I'm still interested in other ideas.

推荐答案

由于 ListBox 的全部目的是显示多个项目并为用户提供选择它们的方法，是的，我会使用不同的控件.

Since the entire purpose of a ListBox is to display multiple items and provide the user with a way to select them, yes, I'd use a different control.

或者你可以这样做，这是进入愚蠢的领域:

Or you could do this, which is getting into the territory of stupid:

<ListBox.ItemContainerStyle>
   <Style TargetType="ListBoxItem">
      <Style.Triggers>
         <Trigger Property="IsSelected" Value="false">
            <Setter Property="Visibility" Value="Collapsed"/>
         </Trigger>
      </Style.Triggers>
   </Style>
</ListBox.ItemContainerStyle>
