获取 ListBox 中的 ListBoxItem [英] Get the ListBoxItem in a ListBox

问题描述

当从 ListBox 中选择它时，我试图更改 ListBoxItem 上的 Control 模板.为此，我将从 ListBox 本身获取选定的 ListBoxItem，并在其上设置控件模板.我该怎么做呢?我已经尝试过 SelectedItem 并返回 ListBoxItem 中的绑定对象.

I am trying to change the Control template on a ListBoxItem when It is selected from the ListBox. To do so, I was going to get the selected ListBoxItem from the ListBox itself, and set the control template on that. How would i go about doing this? I have tried, SelectedItem and that returns the bound object within the ListBoxItem.

推荐答案

您可以使用 ItemContainerGenerator 从绑定的项目中检索项目容器:

You can retrieve the item container from the bound item by using the ItemContainerGenerator :

object selectedItem = listBox.SelectedItem;
ListBoxItem selectedListBoxItem = listBox.ItemContainerGenerator.ContainerFromItem(selectedItem) as ListBoxItem;
