は、どのように私はだから私は、このボタンを持つWPF C＃の

Question

のデフォルトボタンのハイライトを変更することができます。私は、次のイベントのトリガ（IsMouseOverとIsFocused）を追加し、背景を透明に設定しようとしました：

<Style x:Key="ButtonStyle" TargetType="Button"> 

     <Setter Property="FocusVisualStyle" Value="{x:Null}" /> 
     <Setter Property="Template"> 
      <Setter.Value> 
       <ControlTemplate TargetType="Button"> 
        <Border Name="Border" Padding="0" SnapsToDevicePixels="true"> 
         <ContentPresenter /> 
        </Border> 
        <ControlTemplate.Triggers> 
         <Trigger Property="IsMouseOver" Value="true"> 
          <Setter TargetName="Border" Property="Background" Value="Transparent"/> 
         </Trigger> 
         <Trigger Property="IsFocused" Value="True"> 
          <Setter TargetName="Border" Property="Background" Value="Transparent" /> 
          <Setter Property="Background" Value="Transparent" /> 

         </Trigger> 
        </ControlTemplate.Triggers> 
       </ControlTemplate> 
      </Setter.Value> 
     </Setter> 
    </Style> 

ボタンは、このメニューの中にある：

<Menu HorizontalAlignment="Left" Height="40" Margin="0,80,0,0" VerticalAlignment="Top" Width="700" Background="WhiteSmoke"> 
     <Button x:Name="OrderBy" Content="Order By" Width="75" Margin="0,8,0,0" Style="{DynamicResource ButtonStyle}"/> 
     <GridSplitter Height="20" Width="1" Background="Black" Margin="0,8,0,0"/> 
     <Button x:Name="Refresh" Content="Refresh" Width="75" Margin="0,8,0,0"/> 
     <TextBox x:Name="Search" Height="23" TextWrapping="Wrap" Text="Search" Width="240" Margin="250,8,0,0" HorizontalAlignment="Right"/> 
    </Menu> 

私はWPFに新しいですし、私はすでに検索しますこれに対する答えを見つけようとするとたくさんの人がいます。お手伝いありがとう！

MenuItemのControlTemplate、つまりTopLevelItemTemplateを書き換え、IsHighlighted Border's Backgroundのトリガーで透明に設定する必要があります。強調表示はButtonからではなくMenuItemから発生します。 あなたのメニューのリソースにこれを入れて試してみてください。
