想出瞭如何隱藏左側的可笑點，現在我該如何隱藏右側的添加/刪除按鈕下拉箭頭？如何隱藏工具欄右側的箭頭？

谷歌是完全有這個問題的答案：
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);
}
}
，並指定這個方法將你的工具欄Loaded事件。

編輯：也縮小了差距。
編輯2：修復缺少的資源。
或者您可以使用樣式的副本與前面提到的可見性改變和刪除右邊的保證金，所有這些資源都屬於風格/模板：

你嵌入後的某個地方，你可以設置工具欄的樣式：
<ToolBar Style="{DynamicResource ToolBarWithoutOverflowBarStyle}"/>

哇......我不敢相信這需要很多工作才能擁有簡單的工具欄。 – mpen

如果你不想抓握和下拉菜單，爲什麼你要使用工具欄？你可以使用某種類型的面板。 –

@Ralph：如果你有Expression Blend，它沒有太多的工作，它可以提取默認的模板，這就是我在這裏做的。 Blend對模板，樣式等非常有用。 –

將以下方法分配給您的工具欄中的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);
}
}

這適用於水平工具欄。對於垂直工具欄，箭頭不會出現在最後一個按鈕的下方，但在其旁邊（右側，如果工具欄位於窗口的左側）。 –
+0
在定向的情況下。垂直的邊緣應該是厚度（0,0,0,11） –

我已經搜索了四個小時，以正確使用MVVM（所以沒有代碼背後）。
最重要的是ToggleButton之後和ToolBarOverflowPanel（我已將導航示例中的背景顏色設置爲黑色）之後的「可見性摺疊」。
這裏是你可以通過"<toolbar Style="{StaticResource ToolBar}" Background="Black">...</ToolBar>
這裏您工具欄上設置的代碼樣式的代碼：
<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>

我不是很確定你確實需要一個工具欄或類似組件的菜單欄。這正是我想要的：
<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>
它可能不適合你的情況。只是我想分享我的。
