我有一个模板定义如下：

<ListBox.ItemTemplate>
<DataTemplate>

</StackPanel> <ScrollViewer CanContentScroll="True" MinHeight="25" DockPanel.Dock="Left" HorizontalScrollBarVisibility="Auto" VerticalScrollBarVisibility="Disabled">
<ItemsControl ScrollViewer.CanContentScroll="True" DataContext="{Binding}" ItemsSource="{Binding AlertActionsDefinition.Children}" x:Name="lstButton" ButtonBase.Click="lstButton_Click">

列表框与类人绑定。最初，列表框加载了短视图，然后加载该视图以具有上面定义的详细视图模板。我面临的问题是模板内按钮上的点击事件。点击不会在某些时候被解雇，有些时候需要两到三次点击来提升事件。
任何人都可以帮助我追踪它吗？
答案 0 :(得分：0)
我减少了你的代码以适应我的测试，它对我来说非常合适！我正确地收到了所有活动。实际上，每点击一次按钮，我就会收到lstButton_Click两次...（由于Button和ItemsControl级别的冒泡问题。）
