如何使用C＃更新wpf中的列表视图 [英] How to update the List View in wpf using C#

问题描述

我正在开发一个WPF应用程序，其中我有一个带有列表视图的主要wpf表单和一个打开Popup的按钮，该实习生有两个带有Add按钮的文本字段。单击添加按钮后，两个txts将添加到本地系统上的xml文件中，之后将关闭弹出窗口。现在我的要求是，一旦弹出窗口关闭，它的父主窗体ListView应该使用已写入xml文件的txt名称进行更新。



每当我'单击添加按钮，txt名称已添加到xml文件中，弹出窗口将自动关闭。但是当控件返回到主窗体时，listView不会自动更新。请有人帮我这个。



提前致谢。

Hi,
I'm developing a WPF app, in which i have a main wpf form with List View and a button to open a Popup which intern having two text fields with Add button. Once I click the Add button, thew two txts will be added to a xml file on my local system and the popup will be closed after that. Now my requirement is that once the popup is closed, its parent main form ListView should be updated with the txt names which have been written to xml file.

Whenever I'm clicking the Add button the txt names have been added to the xml file and popup is closed automatically. But when the control goes back to the main form, the listView is not updates automatically. Please anyone help me on this.

Thanks in advance.

推荐答案

使用ObservableCollection而不是通用列表并实现INotifyPropertyChange。

Use ObservableCollection instead of generic list and implement INotifyPropertyChange.

我想你也可以手动刷新你的项目：listView.Items.Refresh（）

i think you could also manually refresh your items with: listView.Items.Refresh()
