问题描述
我有保存按钮的StackPanel中，我添加了一个文本菜单，使每个项目可以通过选择固定到开始屏幕菜单项。我会如何确定哪个按钮已被选中点击事件？
MainPage.xaml中
＆LT; StackPanel中的HorizontalAlignment =左方向=横向＆GT; ＆LT;按钮X：NAME =Tile1HEIGHT =173WIDTH =173保证金=12,0,0,0点击=1_Click风格={StaticResource的ButtonStyle1}工具箱：TiltEffect.IsTiltEnabled = 真＆GT;
＆LT; Button.Content＆GT;
＆lt;图像源=/资产/瓷砖/ 1.png/＆GT;
＆LT; /Button.Content>
＆LT; /按钮＆GT;
＆LT;按钮X：NAME =Tile2HEIGHT =173WIDTH =173保证金=12,0,0,0点击=2_Click风格={StaticResource的ButtonStyle1}工具箱：TiltEffect.IsTiltEnabled = 真＆GT;
＆LT; Button.Content＆GT;
＆lt;图像源=/资产/瓷砖/ 2.png/＆GT;
＆LT; /Button.Content>
＆LT; /按钮＆GT;
＆LT;按钮X：NAME =Tile3HEIGHT =173WIDTH =173保证金=12,0,0,0点击=3_Click风格={StaticResource的ButtonStyle1}工具箱：TiltEffect.IsTiltEnabled = 真＆GT;
＆LT; Button.Content＆GT;
＆lt;图像源=/资产/瓷砖/ 3.png/＆GT;
＆LT; /Button.Content>
＆LT; /按钮＆GT;
＆LT; / StackPanel的＆GT;
＆LT;工具箱：ContextMenuService.ContextMenu＆GT;
＆LT;工具箱：文本菜单X：NAME =文本菜单＆GT;
＆LT;工具箱：菜单项标题=脚开始点击=ContextMenuItem_Tap/＆GT;
＆LT; /工具：文本菜单＆GT;
＆LT; /工具包：ContextMenuService.ContextMenu＆GT;
编辑**
将文本菜单分别为每个按钮。
＆LT; StackPanel中的HorizontalAlignment =左方向=横向＆GT; ＆LT;按钮X：NAME =Tile1HEIGHT =173WIDTH =173保证金=12,0,0,0点击=1_Click风格={StaticResource的ButtonStyle1}工具箱：TiltEffect.IsTiltEnabled = 真＆GT;

解决方案
私人无效MenuItem_Click（对象发件人，RoutedEventArgs E）
{
VAR菜单项=（菜单项）发件人;
VAR ctxMenu =（文本菜单）menuItem.Parent;
VAR tileButton =（按钮）ctxMenu.Owner;
}
I have a StackPanel that holds buttons, and I have added a ContextMenu so that each item may be pinned to the start screen by selecting that MenuItem. How might I determine on the Tap event which button has been selected?
MainPage.xaml
<StackPanel HorizontalAlignment="Left" Orientation="Horizontal">
<Button x:Name="Tile1" Height="173" Width="173" Margin="12,0,0,0" Click="1_Click" Style="{StaticResource ButtonStyle1}" toolkit:TiltEffect.IsTiltEnabled="True">
<Button.Content>
<Image Source="/Assets/Tiles/1.png"/>
</Button.Content>
</Button>
<Button x:Name="Tile2" Height="173" Width="173" Margin="12,0,0,0" Click="2_Click" Style="{StaticResource ButtonStyle1}" toolkit:TiltEffect.IsTiltEnabled="True">
<Button.Content>
<Image Source="/Assets/Tiles/2.png"/>
</Button.Content>
</Button>
<Button x:Name="Tile3" Height="173" Width="173" Margin="12,0,0,0" Click="3_Click" Style="{StaticResource ButtonStyle1}" toolkit:TiltEffect.IsTiltEnabled="True">
<Button.Content>
<Image Source="/Assets/Tiles/3.png"/>
</Button.Content>
</Button>
</StackPanel>
<toolkit:ContextMenuService.ContextMenu>
<toolkit:ContextMenu x:Name="ContextMenu">
<toolkit:MenuItem Header="pin to start" Tap="ContextMenuItem_Tap"/>
</toolkit:ContextMenu>
</toolkit:ContextMenuService.ContextMenu>
Edit**
Place the ContextMenu individually for each button.
<StackPanel HorizontalAlignment="Left" Orientation="Horizontal">
<Button x:Name="Tile1" Height="173" Width="173" Margin="12,0,0,0" Click="1_Click" Style="{StaticResource ButtonStyle1}" toolkit:TiltEffect.IsTiltEnabled="True">
<Button.Content>
<Image Source="/Assets/Tiles/1.png"/>
</Button.Content>
<toolkit:ContextMenuService.ContextMenu>
<toolkit:ContextMenu x:Name="ContextMenu">
<toolkit:MenuItem Header="pin to start" Tap="ContextMenuItem_Tap"/>
</toolkit:ContextMenu>
</toolkit:ContextMenuService.ContextMenu>
</Button>
<Button x:Name="Tile2" Height="173" Width="173" Margin="12,0,0,0" Click="2_Click" Style="{StaticResource ButtonStyle1}" toolkit:TiltEffect.IsTiltEnabled="True">
<Button.Content>
<Image Source="/Assets/Tiles/2.png"/>
</Button.Content>
<toolkit:ContextMenuService.ContextMenu>
<toolkit:ContextMenu x:Name="ContextMenu">
<toolkit:MenuItem Header="pin to start" Tap="ContextMenuItem_Tap"/>
</toolkit:ContextMenu>
</toolkit:ContextMenuService.ContextMenu>
</Button>
<Button x:Name="Tile3" Height="173" Width="173" Margin="12,0,0,0" Click="3_Click" Style="{StaticResource ButtonStyle1}" toolkit:TiltEffect.IsTiltEnabled="True">
<Button.Content>
<Image Source="/Assets/Tiles/3.png"/>
</Button.Content>
<toolkit:ContextMenuService.ContextMenu>
<toolkit:ContextMenu x:Name="ContextMenu">
<toolkit:MenuItem Header="pin to start" Tap="ContextMenuItem_Tap"/>
</toolkit:ContextMenu>
</toolkit:ContextMenuService.ContextMenu>
</Button>
</StackPanel>
解决方案
private void MenuItem_Click(object sender, RoutedEventArgs e)
{
var menuItem = (MenuItem) sender;
var ctxMenu = (ContextMenu) menuItem.Parent;
var tileButton = (Button) ctxMenu.Owner;
}
