已经找到如何隐藏左侧的抓握点，现在要如何隐藏右侧的添加/删除按钮下拉箭头？

谷歌上有很多关于这个问题的答案：
private void ToolBar_Loaded(object sender, RoutedEventArgs e)
{
ToolBar toolBar = sender as ToolBar;
var overflowGrid = toolBar.Template.FindName("OverflowGrid", toolBar) as FrameworkElement;
if (overflowGrid != null)
{
overflowGrid.Visibility = Visibility.Collapsed;
}
var mainPanelBorder = toolBar.Template.FindName("MainPanelBorder", toolBar) as FrameworkElement;
if (mainPanelBorder != null)
{
mainPanelBorder.Margin = new Thickness(0);
}
}
将此方法分配给您的工具栏“已加载”事件。

尝试搜索 Google，但未找到。这会留下右侧的空白，原本应该是按钮的位置...有什么办法可以修复吗？ - mpen
@Andrei：这是哪个属性？我在哪里设置它？编辑：算了，我找到了。但它并没有去除间隙。 - mpen
哦，对不起，一开始我没有意识到你具体指的是哪个间隙。当我为自己移除了溢出时，我没有注意到那个间隙，所以我并没有在意它。我目前看不到简单的方法来消除那个间隙，因此重新设计整个工具栏（就像H.B.回答的那样）可能是唯一的选择。 - Andrei Pana
2我已更新我的回答，以去除空隙，该空隙是由于主面板的边距所致。 - Andrei Pana
1哦，这个哲学理论认为这确实是一种hacky的做法，但是移除溢出按钮并没有通过属性暴露（就像左侧手柄一样）。这意味着为工具栏设计的外观不打算缺少溢出组件。要摆脱它，您需要为工具栏定义一个新的样式/外观，一个没有溢出的外观，这意味着重写整个控件模板（正如H.B.所建议的那样），但您必须在模板中包含所有工具栏的功能。FindName本身并不是hacky的（事实上，在自定义控件开发中经常使用）。 - Andrei Pana

将以下方法分配给您的工具栏SizeChanged事件。
private void ToolBar_SizeChanged(object sender, SizeChangedEventArgs e)
{
ToolBar toolBar = sender as ToolBar;
var overflowGrid = toolBar.Template.FindName("OverflowGrid", toolBar) as FrameworkElement;
if (overflowGrid != null)
{
overflowGrid.Visibility = toolBar.HasOverflowItems ? Visibility.Visible : Visibility.Collapsed;
}
var mainPanelBorder = toolBar.Template.FindName("MainPanelBorder", toolBar) as FrameworkElement;
if (mainPanelBorder != null)
{
var defaultMargin = new Thickness(0, 0, 11, 0);
mainPanelBorder.Margin = toolBar.HasOverflowItems ?defaultMargin: new Thickness(0);
}
}

这对于水平工具栏非常完美。对于垂直工具栏，箭头不会出现在最后一个按钮下方，而是在其旁边（如果工具栏位于窗口左侧，则在右侧）。 - char m
如果方向为垂直，则边距应为Thickness(0, 0, 0, 11)。 - char m

编辑: 已经修复了缝隙。
编辑2: 修复了缺失的资源。
或者您可以使用早期提到的可见性更改和右侧边距移除的样式/模板副本，所有这些资源都属于样式/模板:

在您将其嵌入某个位置之后，您可以设置工具栏的样式：
<ToolBar Style="{DynamicResource ToolBarWithoutOverflowBarStyle}"/>

5哇...难以置信为了拥有一个简单的工具栏需要那么多的工作。 - mpen
如果你不想要手柄和下拉菜单，为什么还要使用工具栏呢？你可以直接使用某种面板。 - Robert Rossney
1@Ralph：如果你有Expression Blend，这并不需要太多的工作，它可以提取默认模板，这就是我在这里所做的。Blend对于模板、样式等方面非常有用。 - H.B.

我已经寻找四个小时，用MVVM（所以没有代码后台）才能正确地完成这项任务。
最重要的是在ToggleButton和ToolBarOverflowPanel之后设置“visibility collapsed”（我已经为我的导航示例将背景颜色设置为黑色）。
这里是你可以在工具栏上设置的代码："<toolbar Style="{StaticResource ToolBar}" Background="Black">...</ToolBar>
这里是样式的代码：
<Style x:Key="Toolbar" TargetType="{x:Type ToolBar}">
<Setter Property="SnapsToDevicePixels" Value="true"/>
<Setter Property="OverridesDefaultStyle" Value="true"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ToolBar}">
<Border x:Name="Border" CornerRadius="2" BorderThickness="1" Background="Black" BorderBrush="Black">
<DockPanel >
<ToggleButton Visibility="Collapsed" DockPanel.Dock="Right" IsEnabled="False" IsChecked="False" ClickMode="Press">
<Popup x:Name="OverflowPopup" AllowsTransparency="true" Placement="Bottom" IsOpen="{Binding Path=IsOverflowOpen,RelativeSource={RelativeSource TemplatedParent}}" StaysOpen="false" Focusable="false" PopupAnimation="Slide">
<Border x:Name="DropDownBorder" Background="pink" BorderThickness="1" BorderBrush="pink">
<ToolBarOverflowPanel x:Name="PART_ToolBarOverflowPanel" Margin="2" WrapWidth="200" Focusable="true" FocusVisualStyle="{x:Null}" KeyboardNavigation.TabNavigation="Cycle" KeyboardNavigation.DirectionalNavigation="Cycle" Visibility="Collapsed"/>
</Border>
</Popup>
</ToggleButton>
<ToolBarPanel x:Name="PART_ToolBarPanel" IsItemsHost="true" Margin="0,1,2,2"/>
</DockPanel>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>

我也找了一段时间，没有找到一个优雅的XAML解决方案，这个很好用，非常感谢！ - JEllery
感谢您的帮助，我已经移除了x:Key="Toolbar"并将其放置在资源部分，以简化<toolbar…声明。同时，我还移除了背景和边框笔刷设置。 - Moon Waxing

我不太确定你是否真的需要一个工具栏或类似菜单栏的组件。这里只是我想要的：
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<Menu Grid.Row="0">
<MenuItem Header="Menu1" Padding="10 4">
<MenuItem Header="MenuItem1"/>
<MenuItem Header="MenuItem2"/>
</MenuItem>
<MenuItem Header="Menu2" Padding="10 4">
<MenuItem Header="MenuItem1"/>
<MenuItem Header="MenuItem2"/>
</MenuItem>
</Menu>
<...>
</Grid>
也许不完全适用于你的情况，但我想分享我的经验。
