很抱歉,如果以前曾经问过这个问题,但是我无法找到解决方案来解决我在相关问题中找到的问题,或者在Google上找到解决方案。
在我的应用程序中,我正在尝试重新创建单词新文档对话框,列在项目的左侧,右侧是带有文本的图标。在Word中,当鼠标悬停时它具有橙色渐变,而当您选择项目时,它具有较暗的渐变。除了在选择项目后更改背景颜色外,我已经重新创建了大部分内容。这是我用来创建它的代码:
<ListView Margin="236,34,17,144" Name="listView1" HorizontalContentAlignment="Stretch">
<ListView.ItemsPanel>
<ItemsPanelTemplate>
<UniformGrid Columns="5" IsItemsHost="True" VerticalAlignment="Top" >
</UniformGrid>
</ItemsPanelTemplate>
</ListView.ItemsPanel>
<ListView.ItemTemplate>
<DataTemplate >
<StackPanel HorizontalAlignment="Center" Width="auto">
<Image Source="images/document32.png" HorizontalAlignment="Center"/>
<TextBlock Text="{Binding}" HorizontalAlignment="Center" />
</StackPanel>
</DataTemplate>
</ListView.ItemTemplate>
<ListView.ItemContainerStyle>
<Style TargetType="{x:Type ListViewItem}" >
<Style.Triggers>
<Trigger Property="IsSelected" Value="true">
<Setter Property="Foreground" Value="Yellow" />
<Setter Property="Background" Value="Orange" />
</Trigger>
<Trigger Property="IsMouseOver" Value="true">
<Setter Property="Foreground" Value="Black" />
<Setter Property="Background">
<Setter.Value>
<LinearGradientBrush EndPoint="0.5,1" StartPoint="1,0">
<GradientStop Color="#d3e7ff" Offset="0.986"/>
<GradientStop Color="#b0d2fc" Offset="0.5"/>
<GradientStop Color="#8ec1ff" Offset="0.51"/>
</LinearGradientBrush>
</Setter.Value>
</Setter>
</Trigger>
</Style.Triggers>
</Style>
</ListView.ItemContainerStyle>
</ListView>
因此,这会创建我想要的外观,鼠标悬停,当我在列表视图中选择一个项目时,它会将字体文本更改为黄色,但它拒绝将背景从默认蓝色更改为橙色,理想情况下,它将是另一个渐变而不是泛滥的颜色。谢谢你的帮助。

您可以执行一些黑客操作,例如覆盖系统颜色键,但很可能您需要提供一个新模板来实现此目的。这是我放在一起的相当漂亮的一个:
<Style x:Key="ListboxItemStyle" TargetType="{x:Type ListBoxItem}">
<Setter Property="Margin" Value="1,2,1,1"/>
<Setter Property="HorizontalAlignment" Value="Stretch" />
<Setter Property="Background" Value="{StaticResource NormalItemBackground}" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ListBoxItem}">
<Grid>
<Border Background="{TemplateBinding Background}" />
<Border Background="#BEFFFFFF" Margin="3,1">
<Grid>
<Grid.RowDefinitions>
<RowDefinition />
<RowDefinition />
</Grid.RowDefinitions>
<Border Margin="2,1,2,0" Grid.Row="0" Background="#57FFFFFF" />
</Grid>
</Border>
<ContentPresenter Margin="8,5" />
</Grid>
<ControlTemplate.Triggers>
<MultiTrigger>
<MultiTrigger.Conditions>
<Condition Property="IsMouseOver" Value="True" />
<Condition Property="IsSelected" Value="False"/>
</MultiTrigger.Conditions>
<Setter Property="Background" Value="{StaticResource HotItemBackground}" />
</MultiTrigger>
<Trigger Property="IsSelected" Value="True">
<Setter Property="Background" Value="{StaticResource SelectedItemBackground}" />
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
<Style x:Key="ListBoxStyle" TargetType="{x:Type ListBox}">
<Setter Property="ItemContainerStyle" Value="{DynamicResource ListboxItemStyle}" />
<Setter Property="Margin" Value="3,3,2,1" />
</Style>
