禁用/更改ListView中悬停的颜色
本文关键字：悬停 颜色 ListView 更改 禁用 | 更新日期: 2023-09-27 18:25:45
我目前正在使用wpf，它在列表视图中包含一个网格视图。我可以使用以下代码更改GridViewColumnHeader。然而，我试图使用相同的<ListView.Resources>标签更改悬停选项的颜色/禁用，但不起作用。它目前给了我默认的鼠标颜色浅蓝色，这是我不想要的。
<ListView Margin="10,53,10,65" Name="listView" Background=" black" Foreground="White" BorderThickness="0">
<ListView.Resources>
<Style TargetType="GridViewColumnHeader">
<Setter Property="Background" Value="Black" />
<Setter Property="Foreground" Value="White" />
</Style>
</ListView.Resources>
<ListView.View>
<GridView x:Name="gridView" >
<GridView.Columns>
<GridViewColumn Width="120" DisplayMemberBinding="{Binding Time}" >
<GridViewColumn.Header>
<GridViewColumnHeader Tag="Time" Click="lvUsersColumnHeader_Click">Accessed Time</GridViewColumnHeader>
</GridViewColumn.Header>
</GridViewColumn>
<GridViewColumn Header="Username" Width="100" DisplayMemberBinding="{Binding UserName}" ></GridViewColumn>
<GridViewColumn Header="Location" Width="250" DisplayMemberBinding="{Binding Address}" ></GridViewColumn>
<GridViewColumn Header="File Accessed" Width="100" DisplayMemberBinding="{Binding FileName}" ></GridViewColumn>
<GridViewColumn Header="Remarks" Width="155" DisplayMemberBinding="{Binding Remarks}" ></GridViewColumn>
</GridView.Columns>
</GridView>
</ListView.View>
</ListView>
要覆盖任何控件的默认行为（例如ListView），必须定义ControlTemplate，并且有触发器来设置属性。例如：
<Style x:Key="{x:Type GridViewColumnHeader}" TargetType="{x:Type GridViewColumnHeader}">
<Setter Property="HorizontalContentAlignment" Value="Center" />
<Setter Property="VerticalContentAlignment" Value="Center" />
<Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type GridViewColumnHeader}">
<Grid>
....
如果没有它，系统将采用默认主题的触发器（以及其他行为），这些触发器有自己的样式和模板。
为了验证这一点，您可以下载MSDN上任何控件的样式/模板示例。此处提供了ListView的样式示例。
Note:只需将内容放在Resources中即可。最好将样式放入文件App.xaml或ResourceDictionary中。
MSDN风格的例子（有点大，所以你必须自己决定删除什么，保留什么）：
