wpf 路由事件如何获得子控件的父控件

Answer 1

通过VisualTreeHelper去取就行了。给你段代码参考：
前台：
<Grid Name="rootGrid">
<Grid Name="myGrid" Width="150" Height="150" Background="LightBlue">
<Button Name="btn" Click="btn_Click" Width="80" Height="25" Content="click"/>
</Grid>
</Grid>
后台：
private void btn_Click(object sender, RoutedEventArgs e)
{
Button btn = sender as Button;
var a = VisualTreeHelper.GetParent(btn);
}
然后你断点看下a，就会发现它就是button的父容器myGrid
