WPF - 如何设置菜单控件的样式以删除左边距？
我已向用户控件添加了默认菜单控件。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。我怎么能这样做？
XAML：
<Menu>
<MenuItem Header="MyMenu" FontSize="10">
<MenuItem Header="Options..." />
<MenuItem Header="About" />
</MenuItem>
</Menu>
它目前呈现与开箱即用的任何其他菜单控件一样：
我不希望菜单项左边的边距或列。这通常用于图标等。

这不是很直接，但你需要通过Expression Blend创建一个最简单的MenuItemStyle：
<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。我附上了一个删除了边距的示例项目。 Download sample project here.

我认为这就是你所追求的（再一次，使用Expression Blend解决它，但它是我所能得到的最简约的......它花了很多时间玩） ...您可以在空白的WPF应用程序中删除以下内容作为示例：

这里有两个选项：
-
简短，直接。为
ItemsPanelTemplate或MenuItem设置ContextMenu，具体取决于您使用的菜单类型（请参阅details）。 -
自由基。从头开始重写
Menu样式。有两种随时可用的样式：- 来自MahApps.Metro的
Menu的XAML风格（ordinary Menu和ContextMenu） - Jeff Wilcox的风格激发了前一个来自MahApps的风格（link）

我的简单方法是在ItemTemplate中使用Grid的负边距
<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>

我正在使用WPF Notifyicon（hardcodet）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>
答案 5 :(得分：1)
要删除空间并且从不使用图标，您必须更改MenuItem.SubmenuItemTemplateKey的模板或MenuItem的模板。 如果你只是需要阅读垂直线并继续使用这个answare的图标空间。
带网格的Windows将CustomContextMenu.xaml作为网格资源：
<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.xaml，它有一个CustomSeparatorStyle模板，用于将分隔线扩展到上下文菜单的左边距。还有一个ContextMenu模板来隐藏垂直线。
<ResourceDictionary
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<!-- Outer menu -->
<Style TargetType="{x:Type ContextMenu}">
<Setter Property="OverridesDefaultStyle" Value="True" />
<Setter Property="MaxWidth" Value="295" />
<Setter Property="SnapsToDevicePixels" Value="True" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ContextMenu}">
<!--Here is where you change the border thickness to zero on the menu-->
<Border BorderThickness="1"
x:Name="Border"
CornerRadius="0"
BorderBrush="{TemplateBinding BorderBrush}"

<Border.Effect>
<DropShadowEffect

</Border.Effect>
<StackPanel ClipToBounds="True"

IsItemsHost="True" />
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsMouseOver" Value="true">
<Setter TargetName="Border"
Property="Background"
Value="#F7F7F4" />
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
<!-- Separator -->
<Style TargetType="{x:Type Separator}" x:Key="CustomSeparatorStyle">
<Setter Property="Height" Value="1" />
<Setter Property="Margin" Value="-30,5,0,5"/>
<Setter Property="Background" Value="#F7F7F4" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Separator}">
<Border BorderBrush="#DADAD6" BorderThickness="1" />
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
使用上面的代码创建右边的sude菜单。您可以注意到大小和阴影的差异。为了保持原始菜单的阴影，您必须排除Border.Effect

Simpal和Sort方式如下： 创建ItemsPanelTemplate资源
<ItemsPanelTemplate x:Key="MenuItemPanelTemplate">
<StackPanel Background="White"/>
</ItemsPanelTemplate>
将以下MenuItem样式添加到资源中，您就完成了。
<Style TargetType="{x:Type MenuItem}">
<Setter Property="ItemsPanel" Value="{StaticResource MenuItemPanelTemplate}"/>
</Style>
要将相同的Style应用于ContextMenu，您需要再创建一个Style，如下所示 -
<Style TargetType="{x:Type ContextMenu}">
<Setter Property="ItemsPanel" Value="{StaticResource MenuItemPanelTemplate}"/>
</Style>
也高于上下文菜单，你必须添加
<ContextMenu ItemsSource="{Binding MyItems}" >
<ContextMenu.ItemTemplate>
<DataTemplate>
<TextBlock Margin="-20,0,-40,0" Text="{Binding Name}"/>
</DataTemplate>
</ContextMenu.ItemTemplate>
</ContextMenu>
所以它会覆盖图标空间并显示案例文本块。这是一个简单易用的解决方案。
答案 7 :(得分：0)
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元素都可以放在RadMenuGroupItem中。默认情况下，RadMenuGroupItem的背景颜色为白色，并且与RadMenuItem不同，没有不同颜色的图标区域，因此您可以在下拉列表中轻松使用不同大小的图标。除此之外，RadMenuGroupItem还有一个Header属性，它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：

感谢您成功的想法。对于.net Framework 4.5和VS 2012，我为ContextMenu和MenuItem写了相应的内容：
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;
}
}
