我想在每次更改属性时执行一些代码。以下作品在一定程度上:从DependencyProperty获取父对象PropertyChangedCallback
public partial class CustomControl : UserControl
{
public bool myInstanceVariable = true;
public static readonly DependencyProperty UserSatisfiedProperty =
DependencyProperty.Register("UserSatisfied", typeof(bool?),
typeof(WeeklyReportPlant), new FrameworkPropertyMetadata(new PropertyChangedCallback(OnUserSatisfiedChanged)));
private static void OnUserSatisfiedChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
{
Console.Write("Works!");
}
}
当UserSatisfiedProperty的值更改时,将打印“Works”。问题是我需要访问调用OnUserSatisfiedChanged的CustomControl实例来获取myInstanceVariable的值。我怎样才能做到这一点?
