我有一个ListView，我想在其中禁用蓝色MouseOver/Selection效果。我在网上找到了很多解决方案，但没有一个对我有效。可能是因为我使用的是ItemTemplateSelector吗？这是我的ListView:
<ListView x:Name="lvNachrichten" Margin="10,0,0,5" HorizontalContentAlignment="Stretch" ScrollViewer.HorizontalScrollBarVisibility="Disabled">
<ListView.ItemContainerStyle>
<Style TargetType="ListViewItem">
<Setter Property="Focusable" Value="false"/>
<Style.Triggers>
<Trigger Property="Control.IsMouseOver" Value="True">
<Setter Property="Control.Background" Value="Transparent" />
</Trigger>
</Style.Triggers>
</Style>
</ListView.ItemContainerStyle>
<ListView.Background>
<SolidColorBrush Color="{DynamicResource {x:Static SystemColors.ControlColorKey}}"/>
</ListView.Background>
<ListView.ItemTemplateSelector>
<local:ListViewItemTemplateSelector>
<local:ListViewItemTemplateSelector.SenderTemplate>
<DataTemplate>
<Border Background="PeachPuff" CornerRadius="4" Padding="5,8" HorizontalAlignment="Left" Margin="0,0,0,3" Focusable="False">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" MaxWidth="{Binding ElementName=lvNachrichten, Path=ActualWidth, Converter={StaticResource ArithmeticConv},
ConverterParameter=Int32.Parse(values[0])*0.75}" />
<ColumnDefinition Width="5" />
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="Auto" />
</Grid.ColumnDefinitions>
<TextBlock Grid.Column="0" Text="{Binding MailText}" FontSize="16" TextWrapping="Wrap" />
<!--<CheckBox Grid.Column="2" IsChecked="{Binding gesendet}" IsHitTestVisible="False" VerticalAlignment="Bottom" Template="{StaticResource CheckedImage}" />
<CheckBox Grid.Column="3" IsChecked="{Binding gelesen}" IsHitTestVisible="False" VerticalAlignment="Bottom" Template="{StaticResource CheckedImage}" />-->
<Image Width="28" Height="15" Grid.Column="2" VerticalAlignment="Bottom">
<Image.Source>
<MultiBinding Converter="{StaticResource MessageCheckConv}">
<MultiBinding.Bindings>
<Binding Path="gesendet" />
<Binding Path="gelesen" />
</MultiBinding.Bindings>
</MultiBinding>
</Image.Source>
</Image>
</Grid>
</Border>
</DataTemplate>
</local:ListViewItemTemplateSelector.SenderTemplate>
<local:ListViewItemTemplateSelector.EmpfaengerTemplate>
<DataTemplate>
<Border Background="CornflowerBlue" CornerRadius="4" Padding="5,8" HorizontalAlignment="Right" Margin="0,0,0,3">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="5" />
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="Auto" />
</Grid.ColumnDefinitions>
<TextBlock Grid.Column="0" Text="{Binding MailText}" HorizontalAlignment="Right" FontSize="16" TextWrapping="Wrap" />
<!--<CheckBox Grid.Column="2" IsChecked="{Binding Gesendet}" IsHitTestVisible="False" HorizontalAlignment="Right"/>
<CheckBox Grid.Column="3" IsChecked="{Binding gelesen}" IsHitTestVisible="False" HorizontalAlignment="Right"/>-->
<Image Width="28" Height="15" Grid.Column="2" VerticalAlignment="Bottom">
<Image.Source>
<MultiBinding Converter="{StaticResource MessageCheckConv}">
<MultiBinding.Bindings>
<Binding Path="gesendet" />
<Binding Path="gelesen" />
</MultiBinding.Bindings>
</MultiBinding>
</Image.Source>
</Image>
</Grid>
</Border>
</DataTemplate>
</local:ListViewItemTemplateSelector.EmpfaengerTemplate>
</local:ListViewItemTemplateSelector>
</ListView.ItemTemplateSelector>
</ListView>
您应该重新为ListViewItem的控制模板设置模板，然后您就可以管理它的所有效果。当您将数据模板提供给ListViewItem时，您只需定义数据的外观，从另一方面更改控件模板可以定义控件的视觉行为（例如控件将具有的效果）。您可以尝试使用下一个代码作为起点：1.Xaml编码：
<Window x:Class="SoListBoxStyleHelp.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:system="clr-namespace:System;assembly=mscorlib"
Title="MainWindow" Height="350" Width="525">
<Window.Resources>
<x:Array x:Key="StringArray" Type="system:String">
<system:String>Examle Two</system:String>
<system:String>Examle Three</system:String>
<system:String>Examle Five</system:String>
<system:String>Examle Seven</system:String>
</x:Array>
</Window.Resources>
<Grid>
<ListBox ItemsSource="{StaticResource StringArray}" Background="#00FFFFFF">
<ListBox.ItemContainerStyle>
<Style TargetType="ListBoxItem">
<Setter Property="BorderThickness" Value="1"></Setter>
<Setter Property="BorderBrush" Value="DimGray"></Setter>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="ListBoxItem">
<Grid x:Name="Grid">
<Border x:Name="SimpleBackground" Visibility="Visible" BorderThickness="{TemplateBinding BorderThickness}" BorderBrush="{TemplateBinding BorderBrush}" Background="{TemplateBinding Background}" HorizontalAlignment="Stretch" VerticalAlignment="Stretch"></Border>
<Border x:Name="OnSelectedBackground" Visibility="Collapsed" BorderThickness="{TemplateBinding BorderThickness}" BorderBrush="{TemplateBinding BorderBrush}" Background="Tomato" HorizontalAlignment="Stretch" VerticalAlignment="Stretch"></Border>
<ContentPresenter x:Name="ContentPresenter"></ContentPresenter>
</Grid>
<ControlTemplate.Triggers>
<Trigger Property="IsSelected" Value="True">
<Setter TargetName="OnSelectedBackground" Property="Visibility" Value="Visible"></Setter>
</Trigger>
<Trigger Property="IsSelected" Value="False">
<Setter TargetName="OnSelectedBackground" Property="Visibility" Value="Collapsed"></Setter>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</ListBox.ItemContainerStyle>
</ListBox>
</Grid>
