TextBlock 绑定不起作用,我不知道为什么......
the TextBlock binding does not work and I cant figure why...
(此代码有效,但 TextBlock 未更新)
(This Code Works but the TextBlock does not get Updated )
XAML
<TextBlock x:Name="filterAllText"
Text="{Binding UpdateSourceTrigger=PropertyChanged}" />
代码隐藏
filterAllText.DataContext = LogSession.test.MyCoynt;
C#
public class Test : INotifyPropertyChanged {
public int myCoynt;
public int MyCoynt {
get { return myCoynt; }
set {
myCoynt = value;
NotifyPropertyChanged();
}
}
public event PropertyChangedEventHandler PropertyChanged;
protected virtual void NotifyPropertyChanged(
[CallerMemberName] String propertyName = "") {
PropertyChangedEventHandler handler = PropertyChanged;
if (handler != null) {
handler(this, new PropertyChangedEventArgs(propertyName));
}
}
推荐答案
试试这个:
<TextBlock x:Name="filterAllText"
Text="{Binding UpdateSourceTrigger=PropertyChanged, Path=MyCoynt}" />
并将您的 DataContext
设置为:
filterAllText.DataContext = LogSession.test;
