我有以下代码:
<!-- Accounts list -->
<ListBox SelectedIndex="0" ItemsSource="{Binding AccountViewModels}" SelectedItem="{Binding SelectedItem}" Style="{StaticResource AccountsList}">
<ListBox.ItemContainerStyle>
<Style TargetType="ListBoxItem">
<Setter Property="Padding" Value="0" />
<Setter Property="Margin" Value="0" />
</Style>
</ListBox.ItemContainerStyle>
<ItemsControl.ItemTemplate>
<DataTemplate>
<LocalViews:AccountView Margin="{StaticResource ControlMargin}" />
</DataTemplate>
</ItemsControl.ItemTemplate>
</ListBox>
呈现为:

听起来很糟糕,回答我自己的问题,这是解决方案
<Style TargetType="ListBoxItem" BasedOn="{StaticResource {x:Type ListBoxItem}}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ListBoxItem}">
<ContentPresenter />
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
这会删除ListBoxItem
周围的额外样式,使其看起来好像是ItemsControl
,这正是我想要的。

您可能希望使用ItemsControl
代替ListBox
。它没有选择的概念。
但是,如果要完全控制控件的显示和布局,则需要为控件及其子元素设置自己的控件模板。 MSDN上提供了示例,您也可以使用工具从现有类中提取模板并进行自己的修改。

在Visual Studio或Blend中以设计模式右键单击ListBox,然后选择编辑其他模板 - >编辑生成的项容器(ItemContainerStyle) - &gt;编辑副本以将ListBoxItem的默认控件模板复制到您的XAML标记,然后通过删除一些MultiTriggers来根据您的要求进行编辑:
<ListBox SelectedIndex="0" ItemsSource="{Binding AccountViewModels}" SelectedItem="{Binding SelectedItem}" Style="{StaticResource AccountsList}">
<ListBox.Resources>
<SolidColorBrush x:Key="Item.MouseOver.Background" Color="#1F26A0DA"/>

<SolidColorBrush x:Key="Item.SelectedActive.Background" Color="#3D26A0DA"/>

要删除每个项目周围的填充,可以覆盖ListBoxItem样式中的Padding
属性。
<Style TargetType="ListBoxItem" BasedOn="{StaticResource {x:Type ListBoxItem}}">
<Setter Property="Padding" Value="0" />
</Style>
与您的方法(设置ListBox.ItemContainerStyle
)相比,这不会生成蓝色选择,但是会保留默认列表框的标准选择。
