Question

怎么在一个ListViewItem的事件中根据sender对象找到包含该ListViewItem的ListView对象?

如果换成TreeViewItem的话，代码也是一样的吗

Answer 1

子元素获取父元素对象的代码是一样的

在事件中使用

var target= (sender as Child).Parent as Father

一般只要继承了FrameworkElement的元素 都会有这个Parent的属性

Hi    便携式家园，

获取ListViewItem对象，然后通过VisualTreeHelper帮助类，获取对应的父级对象

        private static T FindParent<T>(DependencyObject dependencyObject) where T : DependencyObject
        {
            var parent = VisualTreeHelper.GetParent(dependencyObject);

            if (parent == null) return null;

            var parentT = parent as T;
            return parentT ?? FindParent<T>(parent);
        }

Best Regards,
