Warum das Feld "Menüelemente" bei der Erstellung in XAML & WPF

Question

links ausgerichtet ist Wenn Sie ein Menü in WPF erstellen, wird das Menüelement linksbündig angezeigt. Gibt es eine Eigenschaft, damit es rechtsbündig erscheint? (Wie Windows-Formulare).

Ich habe überall im Internet ohne Erfolg gesucht und schätze jede Hilfe, die Sie zur Verfügung stellen könnten.

/* XAML-Code */

<Menu> 
     <MenuItem Header="One"> 
      <MenuItem Header="One-One"></MenuItem> 
      <MenuItem Header="One-Two"></MenuItem> 
      <MenuItem Header="One-Three"></MenuItem> 
      <MenuItem Header="One-Four"></MenuItem> 
      <MenuItem Header="One-Five"></MenuItem> 
     </MenuItem> 
     <MenuItem Header="Two"> 
      <MenuItem Header="Two-One"></MenuItem> 
      <MenuItem Header="Two-Two"></MenuItem> 
      <MenuItem Header="Two-Three"></MenuItem> 
      <MenuItem Header="Two-Four"></MenuItem> 
      <MenuItem Header="Two-Five"></MenuItem> 
     </MenuItem> 

    </Menu> 

Answer 1

Sie können die Vorlage der Menüelemente bearbeiten wie diese

<Window.Resources> 
     <ControlTemplate x:Key="MenuItemControlTemplate1" TargetType="{x:Type MenuItem}"> 
      <Border x:Name="templateRoot" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" SnapsToDevicePixels="True"> 
       <Grid VerticalAlignment="Center"> 
        <Grid.ColumnDefinitions> 
         <ColumnDefinition Width="Auto"/> 
         <ColumnDefinition Width="Auto"/> 
        </Grid.ColumnDefinitions> 
        <ContentPresenter x:Name="Icon" Content="{TemplateBinding Icon}" ContentSource="Icon" HorizontalAlignment="Center" Height="16" Margin="3" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" VerticalAlignment="Center" Width="16"/> 
        <Path x:Name="GlyphPanel" Data="F1M10,1.2L4.7,9.1 4.5,9.1 0,5.2 1.3,3.5 4.3,6.1 8.3,0 10,1.2z" Fill="{TemplateBinding Foreground}" FlowDirection="LeftToRight" Margin="3" Visibility="Collapsed" VerticalAlignment="Center"/> 
        <ContentPresenter ContentTemplate="{TemplateBinding HeaderTemplate}" Content="{TemplateBinding Header}" Grid.Column="1" ContentStringFormat="{TemplateBinding HeaderStringFormat}" ContentSource="Header" RecognizesAccessKey="True" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"/> 
        <Popup x:Name="PART_Popup" AllowsTransparency="True" Focusable="False" IsOpen="{Binding IsSubmenuOpen, RelativeSource={RelativeSource TemplatedParent}}" PopupAnimation="{DynamicResource {x:Static SystemParameters.MenuPopupAnimationKey}}" Placement="Bottom"> 
         <Border x:Name="SubMenuBorder" BorderBrush="#FF999999" BorderThickness="1" Background="#FFF0F0F0" Padding="2"> 
          <ScrollViewer x:Name="SubMenuScrollViewer" Style="{DynamicResource {ComponentResourceKey ResourceId=MenuScrollViewer, TypeInTargetAssembly={x:Type FrameworkElement}}}"> 
           <Grid RenderOptions.ClearTypeHint="Enabled"> 
            <Canvas HorizontalAlignment="Left" Height="0" VerticalAlignment="Top" Width="0"> 
             <Rectangle x:Name="OpaqueRect" Fill="{Binding Background, ElementName=SubMenuBorder}" Height="{Binding ActualHeight, ElementName=SubMenuBorder}" Width="{Binding ActualWidth, ElementName=SubMenuBorder}"/> 
            </Canvas> 
            <!--<Rectangle Fill="#FFD7D7D7" HorizontalAlignment="Left" Margin="29,2,0,2" Width="1"/>--> 
            <ItemsPresenter x:Name="ItemsPresenter" KeyboardNavigation.DirectionalNavigation="Cycle" Grid.IsSharedSizeScope="True" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" KeyboardNavigation.TabNavigation="Cycle"/> 
           </Grid> 
          </ScrollViewer> 
         </Border> 
        </Popup> 
       </Grid> 
      </Border> 
      <ControlTemplate.Triggers> 
       <Trigger Property="IsSuspendingPopupAnimation" Value="True"> 
        <Setter Property="PopupAnimation" TargetName="PART_Popup" Value="None"/> 
       </Trigger> 
       <Trigger Property="Icon" Value="{x:Null}"> 
        <Setter Property="Visibility" TargetName="Icon" Value="Collapsed"/> 
       </Trigger> 
       <Trigger Property="IsChecked" Value="True"> 
        <Setter Property="Visibility" TargetName="GlyphPanel" Value="Visible"/> 
        <Setter Property="Visibility" TargetName="Icon" Value="Collapsed"/> 
       </Trigger> 
       <Trigger Property="IsHighlighted" Value="True"> 
        <Setter Property="Background" TargetName="templateRoot" Value="#3D26A0DA"/> 
        <Setter Property="BorderBrush" TargetName="templateRoot" Value="#FF26A0DA"/> 
       </Trigger> 
       <Trigger Property="IsEnabled" Value="False"> 
        <Setter Property="TextElement.Foreground" TargetName="templateRoot" Value="#FF707070"/> 
        <Setter Property="Fill" TargetName="GlyphPanel" Value="#FF707070"/> 
       </Trigger> 
       <Trigger Property="CanContentScroll" SourceName="SubMenuScrollViewer" Value="False"> 
        <Setter Property="Canvas.Top" TargetName="OpaqueRect" Value="{Binding VerticalOffset, ElementName=SubMenuScrollViewer}"/> 
        <Setter Property="Canvas.Left" TargetName="OpaqueRect" Value="{Binding HorizontalOffset, ElementName=SubMenuScrollViewer}"/> 
       </Trigger> 
      </ControlTemplate.Triggers> 
     </ControlTemplate> 
    </Window.Resources> 
    <Grid> 
     <Menu> 
      <MenuItem Header="One" Template="{DynamicResource MenuItemControlTemplate1}"> 
       <MenuItem Header="One-One" Template="{DynamicResource MenuItemControlTemplate1}"></MenuItem> 
       <MenuItem Header="One-Two"></MenuItem> 
       <MenuItem Header="One-Three"></MenuItem> 
       <MenuItem Header="One-Four"></MenuItem> 
       <MenuItem Header="One-Five"></MenuItem> 
      </MenuItem> 
      <MenuItem Header="Two"> 
       <MenuItem Header="Two-One"></MenuItem> 
       <MenuItem Header="Two-Two"></MenuItem> 
       <MenuItem Header="Two-Three"></MenuItem> 
       <MenuItem Header="Two-Four"></MenuItem> 
       <MenuItem Header="Two-Five"></MenuItem> 
      </MenuItem> 

     </Menu> 
    </Grid> 

Answer 2

was für mich gearbeitet ist folgende:

<Menu> 
    <MenuItem Header="_One"> 
     <MenuItem Header="_One-One"></MenuItem> 
     <MenuItem Header="_One-Two"></MenuItem> 
     <MenuItem Header="_One-Three"></MenuItem> 
     <MenuItem Header="_One-Four"></MenuItem> 
     <MenuItem Header="_One-Five"></MenuItem> 
    </MenuItem> 
    <MenuItem Header="_Two"> 
     <MenuItem Header="_Two-One"></MenuItem> 
     <MenuItem Header="_Two-Two"></MenuItem> 
     <MenuItem Header="_Two-Three"></MenuItem> 
     <MenuItem Header="_Two-Four"></MenuItem> 
     <MenuItem Header="_Two-Five"></MenuItem> 
    </MenuItem> 

</Menu> 

Platzieren Sie ein _ vor dem Namen macht es zu einem Hotkey STRG + der Name des Headers, aber meine sind auch gut ausgerichtet.

Das Problem lag im Registrierungs-Editor.

Diese Webseite mein Problem gelöst:

In meinem Fall nur löschen oder auf 0 setzen den Schlüssel "MenuDropAlignment" in HKEY_CURRENT_USER \ Software \ Microsoft \ Windows NT \ Currentversion \ Windows wurde das Problem behoben .

Ich hoffe, diese Antwort hilft anderen Menschen mit dem gleichen Problem.

Und Dank an Leute, die versucht haben zu helfen.
