推荐答案

嗨
"我想在消息框中或表单上的任何位置显示复选框列表框项目，但不阅读我发布的代码.."
无法在System.Windows.MessageBox中显示类似CheckBox的控件.在表格上的任何地方都可以显示内容.

尝试使用System.Collections.ObjectModel.ObservableCollection而不是List.在WinForms中，您必须使用BindingList.

我可以通过将LessonInfo设置为数据源来自动生成ListView(数据->添加已添加的数据源...).然后，我将执行以下操作.

请记住要投票和发表评论.

Displaying controls like CheckBox in a System.Windows.MessageBox is not possible. Displaying something any where on a form is possible.

Try using System.Collections.ObjectModel.ObservableCollection instead of List. In WinForms you had to use BindingList.

I would have auto-generate the ListView by setting LessonInfo as a data source (Data -> Add ned data source...). Then I would done the following.

Remember to vote and comment, please.

ObservableCollection<lessoninfo> _lessInfoCollection;
public MainWindow()
{
    InitializeComponent();
    _lessInfoCollection = new ObservableCollection<lessoninfo>();
    // For debugging
    /*_lessInfoCollection.Add(
           new LessonInfo(isVisited: true, lessonName: "Coding"));
    _lessInfoCollection.Add(
           new LessonInfo(isVisited: false, lessonName: "Implementing"));*/
    lessonInfoListView.ItemsSource = _lessInfoCollection;
        
    conn = new OleDbConnection();
    conn.ConnectionString = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=D:\Software Development\vishal_wpf\dem\WpfApplication11\WpfApplication11\DLL.mdb";
}</lessoninfo></lessoninfo>
