WinRT XAML Cancel Event on Element on Top of Another - xaml

Question

I have a square that has a Tapped event handler. Inside the square (on top of) is another button that has a Flyout. When I click the button to open the Flyout, the event is also fired for the square.
How can I make it so the event isn't fired on the square if the Flyout was clicked?
How can I cancel Handled = true a RoutedEvent that happens through a Command?
Here is the XAML
<Grid Margin="0, 0, 50, 50" Width="300">
<interactivity:Interaction.Behaviors>
<core:EventTriggerBehavior EventName="Tapped">
<core:InvokeCommandAction Command="{Binding DataContext.MyTapCommand, ElementName=LayoutRoot}" CommandParameter="{Binding}" />
</core:EventTriggerBehavior>
</interactivity:Interaction.Behaviors>
<Image Source="{Binding MyImagePath}" Width="300" />
<Border Background="#aa000000" HorizontalAlignment="Stretch" VerticalAlignment="Bottom">
<TextBlock Text="{Binding Title}" Margin="5" FontSize="18" TextWrapping="Wrap" />
</Border>
<Button VerticalAlignment="Top" HorizontalAlignment="Right">
<Button.Template>
<ControlTemplate>
<Grid>
<Canvas Height="50" Width="50">
<Polygon Points="0,0 50,0 50,50 0,0" Fill="Gray" />
<TextBlock Text="+" FontSize="40" Canvas.Top="-16" Canvas.Left="22" Padding="0" />
</Canvas>
</Grid>
</ControlTemplate>
</Button.Template>
<Button.Flyout>
<MenuFlyout>
<MenuFlyoutItem Text="Item 1" Command="{Binding DataContext.Item1Command, ElementName=LayoutRoot}" CommandParameter="{Binding}" />
<MenuFlyoutItem Text="Item 2" Command="{Binding DataContext.Item2Command, ElementName=LayoutRoot}" CommandParameter="{Binding}" />
</MenuFlyout>
</Button.Flyout>
</Button>
</Grid>
So there is an image that is the whole item. You can click the image and a command should fire. There is a button that sits on top of the image. If the button is clicked, I don't want the Tapped event to fire.

Answer 1

I was able to just put a Tapped handler on the button that contains the Flyout and do e.Handled = true. The Flyout still opens but the second event doesn't happen.

Answer 2

i can't reproduce the mentioned issue, anyway i guess your issue can be resolved by the below code snippet,
//Button tapped event
private void Button_Click_1(object sender, RoutedEventArgs e)
{
if ((sender) is Button)
{
// your code
}
}
Therefore when the sender is square it can be omitted.
I hope it helps you.
