[英]WPF Treeview Highlight selected item programmatically
When i rebuild a WPF treeview i want to set the selected item like before the rebuild. 当我重建WPF树视图时,我想像重建之前一样设置选定的项目。 Therefore I set the property IsSelected to true and call the method focus() for the treeviewitem.
因此,我将属性IsSelected设置为true并为treeviewitem调用方法focus()。 But the background of the selected item is only a pale gray color.
但是所选项目的背景只有浅灰色。 How can achieve the standard blue background programmatically.
如何以编程方式达到标准的蓝色背景。 When I click the item with the mouse the item background is blue again.
当我用鼠标单击项目时,项目背景再次变为蓝色。
