我有一个项目,我在一个复选框的IsChecked属性绑定代码隐藏中的get/set.但是,当应用程序加载时,由于某种原因它不会更新.好奇,我把它剥离了它的基础,像这样:
//using statements
namespace NS
{
/// <summary>
/// Interaction logic for MainWindow.xaml
/// </summary>
public partial class MainWindow : Window
{
private bool _test;
public bool Test
{
get { Console.WriteLine("Accessed!"); return _test; }
set { Console.WriteLine("Changed!"); _test = value; }
}
public MainWindow()
{
InitializeComponent();
Test = true;
}
}
}

而且,瞧,当我把它设置为真时,它没有更新!
任何人都可以提出修复,或解释原因?
谢谢,非常感谢.
