将ListBoxItem的IsSelected属性绑定到该对象上的属性 [英] Binding the IsSelected property of ListBoxItem to a property on the object from it's source

问题描述

我有一个WPF ListBox 控件，我正在将其 ItemsSource 设置为项目对象的集合。如何将 ListBoxItem 的 IsSelected 属性绑定到已选择 Binding.Source ？

I have a WPF ListBox control and I'm setting its ItemsSource to a collection of item objects. How can I bind the IsSelected property of the ListBoxItem to a Selected property of a corresponding item object without having an instance of the object to set as a Binding.Source?

推荐答案

只需覆盖ItemContainerStyle：

Just override ItemContainerStyle:

   <ListBox ItemsSource="...">
     <ListBox.ItemContainerStyle>
      <Style TargetType="{x:Type ListBoxItem}">
        <Setter Property="IsSelected" Value="{Binding Selected}"/>
      </Style>
     </ListBox.ItemContainerStyle>
    </ListBox>
