WPF - 如何设置菜单控件的样式以删除左边距？
问题描述 投票：0回答：9
我已将默认菜单控件添加到我的用户控件中。我需要设置菜单样式以删除包含图标或复选框空间的左边距。我该怎么做？
XAML：
<Menu>
<MenuItem Header="MyMenu" FontSize="10">
<MenuItem Header="Options..." />
<MenuItem Header="About" />
</MenuItem>
</Menu>
它目前的渲染方式与任何其他开箱即用的菜单控件一样：
我不希望菜单项左侧有边距或列。这通常用于图标等。

我认为这就是你所追求的（再次，使用Expression Blend来解决它，但就它显示的内容而言，它是我能得到的最简约的......并且花了很多时间来玩弄）.. .您可以将以下内容放入空白 WPF 应用程序中作为示例：

简单快捷的方法如下。创建
ItemsPanelTemplate<ItemsPanelTemplate x:Key="MenuItemPanelTemplate">
<StackPanel Background="White"/>
</ItemsPanelTemplate>
将以下
MenuItem<Style TargetType="{x:Type MenuItem}">
<Setter Property="ItemsPanel" Value="{StaticResource MenuItemPanelTemplate}"/>
</Style>
要将相同的
StyleContextMenuStyle<Style TargetType="{x:Type ContextMenu}">
<Setter Property="ItemsPanel" Value="{StaticResource MenuItemPanelTemplate}"/>
</Style>
在上下文菜单之上，您还必须添加：
<ContextMenu ItemsSource="{Binding MyItems}" >
<ContextMenu.ItemTemplate>
<DataTemplate>
<TextBlock Margin="-20,0,-40,0" Text="{Binding Name}"/>
</DataTemplate>
</ContextMenu.ItemTemplate>
</ContextMenu>
因此它将覆盖图标空间并显示大小写文本块。这是最简单、最容易的解决方案。

这不是很直接，但您需要创建一个 MenuItemStyle，最简单的方法是通过 Expression Blend：
<Menu>
<MenuItem Header="MyMenu" Style="{DynamicResource MenuItemStyle1}">
<MenuItem Header="Options..." />
<MenuItem Header="About" />
</MenuItem>
</Menu>
它创建了一组极其冗长的模板和样式，您需要编辑菜单项以删除网格的固定宽度第一列，然后在 SubMenuBorder ContentControl 模板中删除形成背景阴影的矩形。我附上了一个已删除边距的示例项目。 在此处下载示例项目。

这里有两个选项：
简短、简单、直接。将
设置为ItemsPanelTemplate
或MenuItem
，具体取决于您使用的菜单类型（请参阅详细信息）。ContextMenu激进。从头开始重写
风格。有两种即用型：Menu-
来自 MahApps.Metro 的
- XAML 风格的
（普通菜单和ContextMenu）Menu - Jeff Wilcox 的风格启发了 MahApps 的前一个风格（link）

我的简单方法是在 ItemTemplate 中为网格使用负边距
<ContextMenu.ItemTemplate>
<DataTemplate>
<Grid Margin="-20,0,-40,0"><!--this part is important-->
<Grid.ColumnDefinitions>
<ColumnDefinition Width="20"/>
<ColumnDefinition Width="1*"/>
</Grid.ColumnDefinitions>
<TextBlock Grid.Column="0" Text="{Binding Ident}"/>
<TextBlock Grid.Column="1" Text="{Binding Description}"/>
</Grid>
</DataTemplate>
</ContextMenu.ItemTemplate>

我正在使用 WPF Notifyicon（硬编码）并使用以下代码删除了菜单的图标部分：
<Window ...>
<Window.Resources>
<ItemsPanelTemplate x:Key="MenuTPL">
<StackPanel Margin="-30,0,0,0" Background="White"/>
</ItemsPanelTemplate>
</Window.Resources>
<Grid>
...
<ContextMenu>
<ContextMenu.Style>
<Style TargetType="{x:Type ContextMenu}">
<Setter Property="ItemsPanel" Value="{StaticResource MenuTPL}"/>
</Style>
</ContextMenu.Style>
<MenuItem Header="Exit" Click="Exit_MenuItemClick"/>
</ContextMenu>
...
</Grid>
</Window>

要删除空格并且从不使用图标，您必须更改
MenuItem.SubmenuItemTemplateKeyMenuItem带有网格的 Windows 有我的
CustomContextMenu.xaml<Window ...>
<Grid>
<Grid.Resources>
<ResourceDictionary Source="CustomContextMenu.xaml"/>
</Grid.Resources>
<Grid.ContextMenu>
<ContextMenu>
<MenuItem Header="Menu item 1" >
<MenuItem Header="Menu item 2" >
<MenuItem.Icon>
<Image Source="icon.jpg"/>
</MenuItem.Icon>
</MenuItem>
</MenuItem>
<Separator Style="{StaticResource MySeparatorStyle}" />
<MenuItem IsEnabled="False" Header="Menu item 3" />
</ContextMenu>
</Grid.ContextMenu>
<TextBlock>test</TextBlock>
</Grid>
</Window>
这是我的
CustomContextMenu.xamlCustomSeparatorStyle<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<!-- Outer menu -->

</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
<!-- Separator -->
<Style x:Key="CustomSeparatorStyle" TargetType="{x:Type Separator}">
<Setter Property="Height" Value="1" />
<Setter Property="Margin" Value="-30,5,0,5" />
<Setter Property="Background" Value="#F7F7F4" />
<Setter Property="Template">

<ControlTemplate TargetType="{x:Type Separator}">
<Border BorderBrush="#DADAD6" BorderThickness="1" />
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</ResourceDictionary>
右侧菜单是使用上面的代码创建的。您可以注意到大小和阴影的差异。为了保留原始菜单的阴影，您必须排除
Border.Effect

使用 RadMenuGroupItem。
RadMenuGroupItem 继承自 RadMenuItem 类，它用作 RadMenuItem 下拉列表的容器。换句话说，任何 UI 元素都可以放置在 RadMenuGroupItem 内部。默认情况下，RadMenuGroupItem 的背景颜色为白色，并且没有与 RadMenuItem 不同颜色的图标区域，因此您可以轻松地在下拉列表中使用不同大小的图标。除此之外，RadMenuGroupItem 还有一个 Header 属性，该属性显示在所有组项的顶部。
<telerik:RadMenu VerticalAlignment="Top">
<telerik:RadMenuItem Header="Shapes" />
<telerik:RadMenuItem Header="Sizes">
<telerik:RadMenuGroupItem Header="Header">
<telerik:RadMenuItem Header="Small" IconTemplate="{StaticResource IconTemplate}" IconColumnWidth="35" Height="35" />
<telerik:RadMenuItem Header="Medium" IconTemplate="{StaticResource IconTemplate}" IconColumnWidth="45" Height="45" />
<telerik:RadMenuItem Header="Large" IconTemplate="{StaticResource IconTemplate}" IconColumnWidth="55" Height="55" />
</telerik:RadMenuGroupItem>
</telerik:RadMenuItem>
这就是结果：

感谢您的成功想法。对于 .net Framework 4.5 和 VS 2012，我相应地为 ContextMenu 和 MenuItem 编写了：
private const double ICON_SIZE = 32;
void ContextMenu_Loaded(object sender, System.Windows.RoutedEventArgs e)
{
if (_pointerControl.ContextMenu.Template != null)
{
System.Windows.Shapes.Rectangle r1 = _pointerControl.ContextMenu.Template.FindName("3_T", _pointerControl.ContextMenu) as System.Windows.Shapes.Rectangle;
System.Windows.Shapes.Rectangle r2 = _pointerControl.ContextMenu.Template.FindName("4_T", _pointerControl.ContextMenu) as System.Windows.Shapes.Rectangle;
System.Windows.Shapes.Rectangle r3 = _pointerControl.ContextMenu.Template.FindName("5_T", _pointerControl.ContextMenu) as System.Windows.Shapes.Rectangle;
double width = Math.Max(28, ICON_SIZE+14);
r1.Width = width;
r2.Margin = new System.Windows.Thickness(width + 1, 2, 0, 2);
r3.Margin = new System.Windows.Thickness(width + 2, 2, 0, 2);
}
}
void mi_Loaded(object sender, System.Windows.RoutedEventArgs e)
{
System.Windows.Controls.MenuItem mi = sender as System.Windows.Controls.MenuItem;
if (mi != null && mi.Template != null)
{
System.Windows.Controls.ContentPresenter cp = mi.Template.FindName("Icon", mi) as System.Windows.Controls.ContentPresenter;
cp.Height = ICON_SIZE + 6;
cp.Width = ICON_SIZE + 6;
}
}
