樣式MenuItem按預期工作

以下是創建這個菜單中的XAML：

<Menu Grid.Column="0" ItemsSource="{Binding ParentButtons}" > 

    <Menu.ItemsPanel> 
     <ItemsPanelTemplate> 
      <VirtualizingStackPanel Orientation="Vertical"/> 
     </ItemsPanelTemplate> 
    </Menu.ItemsPanel> 

    <Menu.Resources> 
     <Style TargetType="{x:Type MenuItem}">

        <Path.Resources> 
         <Style TargetType="{x:Type Path}"> 
          <Setter Property="Fill" Value="#FFFFFFFF" /> 
          <Style.Triggers>

       </Path> 
       <TextBlock Text="{Binding Title}" VerticalAlignment="Center">

           </Trigger> 
          </Style.Triggers> 
         </Style> 
        </TextBlock.Resources> 
       </TextBlock> 
      </StackPanel> 
     </HierarchicalDataTemplate> 
    </Menu.ItemTemplate> 

</Menu>

但我有1個問題：

當我將鼠標放置到路徑（它的工作好）：

當我mouseOver MenuItem（它不按預期工作）：

第二種情況應該是什麼樣的行爲？ –

第二種情況下的行爲應該是：當我mouseover MenuItem時，路徑的背景應該改變，如第一幅圖所示。 – Vishal

試試這個：在我的情況下stackpanel作爲AncestorType不起作用，所以我用Menuitem。

  <StackPanel> 
        <Path x:Name="PathData" Data="M 0 0 L 0 5 L 5 5 Z" Stretch="Uniform" Width="32" Height="32" RenderTransformOrigin="0.5,0.5"> 
         <Path.RenderTransform> 
          <TransformGroup> 
           <TransformGroup.Children> 
            <RotateTransform Angle="0"/> 
            <ScaleTransform ScaleX="1" ScaleY="1" /> 
           </TransformGroup.Children> 
          </TransformGroup> 
         </Path.RenderTransform> 
         <Path.Style> 
          <Style TargetType="{x:Type Path}"> 
           <Setter Property="Fill" Value="Transparent" /> 
           <Style.Triggers> 
            <DataTrigger Binding="{Binding RelativeSource={RelativeSource Mode=FindAncestor,AncestorType={x:Type MenuItem}},Path=IsMouseOver}" Value="True"> 
             <Setter Property="Fill" Value="Green" /> 
            </DataTrigger> 
           </Style.Triggers> 
          </Style> 
         </Path.Style> 
        </Path> 
       </StackPanel>

是的，DataTrigger會訣竅。感謝您一次又一次的幫助我。 – Vishal

@訪問你是最受歡迎的。 –

您所在位置的資源是不正確的更換：

 <Path.Resources> 
      <Style TargetType="{x:Type Path}"> 
       <Setter Property="Fill" Value="#FFFFFFFF" /> 
       <Style.Triggers> 
        <DataTrigger Binding="{Binding RelativeSource={RelativeSource AncestorType=StackPanel,AncestorLevel=1}, Path=IsMouseOver}" Value="True" > 
         <Setter Property="Fill" Value="{Binding MouseOverColor}" /> 
        </DataTrigger> 

       </Style.Triggers> 
      </Style> 
     </Path.Resources>

並添加Background="#01000000"到StackPanel中，它能夠檢測IsMouseOver屬性。

現在它會起作用。此致敬禮。

好的。但是Heena Patil給出了更完美的答案。所以，我已經將它標記爲接受的答案。感謝你們對我的幫助。 – Vishal

+1，因爲我們的appraoch是相同的，但stackpanel作爲AncestorType在我的情況下不起作用。 –
