WPF 使用DataGrid绑定数据，并添加编辑和删除按钮

xaml

使用DataGridTemplateColumnkey在一列添加多个控件，这里添加了2个按钮，编辑和删除

数据绑定，直接从DataTable中读取数据绑定

UserViewModel userModel = new UserViewModel();
            this.userList.ItemsSource = userModel.GetUser().DefaultView;

编辑

我使用了页面跳转编辑，觉得这样好看点，用弹窗感觉不好看

private void UserEditClick(object sender, RoutedEventArgs e)
        {
            Button btn = sender as Button;
            if (btn != null)
            {
                int id = Convert.ToInt32(btn.Tag);
                User user = new User(id);
                this.NavigationService.Navigate(user);
            }
        }

编辑页面需要多一个构造函数接收参数

public User(int id)
        {
            InitializeComponent();
            if (id != 0)
            {
                this._id = id;
                EditUserInit(this._id);
            }
        }

编辑直接从DataRow中读取数据

public void EditUserInit(int id)
        {
            UserViewModel userModel = new UserViewModel();
            Dictionary user = userModel.GetUserRowById(id);
            this.nameTxt.Text = user["name"].ToString();
            this.userSnTxt.Text = user["user_sn"].ToString();
        }

删除

private void UserDeleteClick(object sender, RoutedEventArgs e)
        {
            Button btn = sender as Button;
            if (btn != null)
            {
                int id = Convert.ToInt32(btn.Tag);
                UserViewModel userModel = new UserViewModel();
                userModel.DeleteUser(id);
                MessageBox.Show("删除成功");
                this.userList.ItemsSource = userModel.GetUser().DefaultView;
            }
        }
