ListView.ItemContainerStyle内的ContextMenu命令绑定无效可能是由于以下原因导致的:
针对以上问题,可以尝试以下解决方案:
<ListView>
<ListView.ItemContainerStyle>
<Style TargetType="ListViewItem">
<Setter Property="ContextMenu">
<Setter.Value>
<ContextMenu PlacementTarget="{Binding PlacementTarget, RelativeSource={RelativeSource AncestorType=ContextMenu}}">
<!-- 其他菜单项 -->
</ContextMenu>
</Setter.Value>
</Setter>
</Style>
</ListView.ItemContainerStyle>
</ListView>
<ListView>
<ListView.ItemContainerStyle>
<Style TargetType="ListViewItem">
<Setter Property="ContextMenu">
<Setter.Value>
<ContextMenu PlacementTarget="{Binding PlacementTarget, RelativeSource={RelativeSource AncestorType=ContextMenu}}">
<MenuItem Header="命令示例" Command="{Binding DataContext.YourCommand, RelativeSource={RelativeSource AncestorType=ContextMenu}}"/>
</ContextMenu>
</Setter.Value>
</Setter>
</Style>
</ListView.ItemContainerStyle>
</ListView>
其中,YourCommand应替换为实际的命令属性。
<ListView>
<ListView.ItemContainerStyle>
<Style TargetType="ListViewItem">
<Setter Property="ContextMenu">
<Setter.Value>
<ContextMenu PlacementTarget="{Binding PlacementTarget, RelativeSource={RelativeSource AncestorType=ContextMenu}}">
<MenuItem Header="命令示例" Command="{Binding DataContext.YourCommand, RelativeSource={RelativeSource AncestorType=ContextMenu}}" CommandParameter="{Binding}"/>
</ContextMenu>
</Setter.Value>
</Setter>
</Style>
</ListView.ItemContainerStyle>
</ListView>
其中,YourCommand应替换为实际的命令属性。
<ListView>
