我正在ScatterView
使用模板动态创建项目:
<s:ScatterView.ItemTemplate >
<DataTemplate>
<DockPanel LastChildFill="True" >
<DockPanel.Background>
<ImageBrush ImageSource="{Binding Type, Converter={StaticResource imgSelector}}"
Stretch="Fill" />
</DockPanel.Background>
<TextBox Background="Transparent" DockPanel.Dock="Top" Text="{Binding Path=Message}"
IsReadOnly="True" TextWrapping="Wrap" />
<s:ElementMenu Name="emBallMenu" VerticalAlignment="Top"
ActivationMode="HostInteraction" ActivationHost="?????">
<s:ElementMenuItem Header="Send back" x:Name="emiSendBack"
Command="local:MainSurfaceWindow.MenuItemCommand"
CommandParameter="{Binding Path=BallId}"/>
</s:ElementMenu>
</DockPanel>
</DataTemplate>
</s:ScatterView.ItemTemplate>
我应该在 的ActivationHost
中设置什么,emBallMenu
以便通过手指点击父菜单来激活菜单ScatterView.ItemTemplate
?
