我是WPF / MVVM的初学者，我有很多问题.. 其中一个，我在左边是一个带有LoginView的应用程序，左边是一个内容视图。 这两个视图在MainView中是这样的： First View＆＃34; MainWindow＆＃34;

点击我的ConnexionView上的“登录”按钮后，我想启用= true我的视图。 我尝试了很多东西，没有任何作用。

问题在于我的观察能力变得强大，我对此变得疯狂。

提前感谢您的帮助。

答案 0 :(得分：0)

请务必将INotifyPropertyChanged事件提升一次并放在正确的位置，以便所有“订阅者”都知道旧值和新值的更改。因为你多次提出这个事件，我怀疑“订阅者”基本上被告知价值已被更新 - 旧值：false，新值：false。

如果没有看到整个解决方案和最新代码，很难准确诊断问题，这里是我刚刚从您原始帖子中重构的代码，点击按钮调用ButtonCommand它立即将EnabledView属性设置为与当前相反的属性，这为我启用和禁用MigrationModeleView。
