wpf - 通过父级上的点击事件获取子级

Question

有没有一种方法可以让我点击 WrapPanel 的子项并获取子项，而不必在每个子项中插入 Click 事件？我可以只在 WrapPanel 上插入一个 Click 事件吗？

我的代码如下:

    <ScrollViewer Name="scrollViewer" HorizontalScrollBarVisibility="Disabled" VerticalScrollBarVisibility="Auto" Height="500" Margin="1085,154,-89,0" HorizontalAlignment="Left" Width="267" VerticalAlignment="Top">
        <WrapPanel Name="Agenda" HorizontalAlignment="Left" Height="Auto" VerticalAlignment="Top" Width="265" Background="#FFEEF4FF">
            <Border Name="b06x00" BorderThickness="1" Width="265" BorderBrush="Black" Visibility ="Visible">
                <TextBlock TextWrapping="Wrap" Text="06:00" Width="265" Height="15" Background="White"/>
            </Border>
            ...
            this Border + TextBlock is repeated 70 times. It's an agenda by the way.
            ...
        </WrapPanel>
    </ScrollViewer>

例如，您可以在 WrapPanel 上处理 MouseDown 事件，因为它会从该面板中的任何控件冒泡

<WrapPanel Name="Agenda" ... MouseDown="Agenda_MouseDown">

在事件处理程序中，您可以像这样检查 OriginalSource:

private void Agenda_MouseDown(object sender, MouseButtonEventArgs e)
{
   var textBlock = e.OriginalSource as TextBlock;
}
