当焦点移到WPF ListBox中时，所选项目会失去样式 [英] Selected item loses style when focus moved out in WPF ListBox

问题描述

我有什么?

我有一个ListBox，其中填充了XML文件中的项目.给定Style属性的DynamicResource并为ItemContainerStyle中的IsSelected编写了触发器.

I have a ListBox populated with items from an XML file. Given a DynamicResource for Style property and written trigger for IsSelected in ItemContainerStyle.

我想做什么?

即使焦点移出ListBox，我仍要保持所选项目的突出显示.

I want to keep the selected Item highlighted even after focus moved out of the ListBox.

我遇到什么问题?

当我选择一个项目时，在IsSelected触发器中指定的样式有效.但是，当我将焦点移出列表框(按Tab或单击其他控件)时，所选项目便失去了样式.有什么办法可以保留所选的商品样式?

When I select an item the style specified in IsSelected trigger works. But, when I move the focus out of list box (press tab or click on some other control) the selected item loses its style. Is there any way so that I can retain the selected item style?

提前谢谢！
