WPF TextBlock text Binding

Question

the TextBlock binding does not work and I cant figure why...

(This Code Works but the TextBlock does not get Updated )

XAML

<TextBlock x:Name="filterAllText" Text="{Binding UpdateSourceTrigger=PropertyChanged}" />

Codebehind

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)); } }

The Binding needs a Path, i.e {Binding MyCoynt, UpdateSourceTrigger=PropertyChanged}" — default

Try this:

<TextBlock x:Name="filterAllText" Text="{Binding UpdateSourceTrigger=PropertyChanged, Path=MyCoynt}" />

And set your DataContext like:

filterAllText.DataContext = LogSession.test;

<TextBlock x:Name="filterAllText" Text="{Binding Path=., UpdateSourceTrigger=PropertyChanged}" />

EDIT: the better way is the anwser from Goanne

oh, I didn't see that he set the DataContext to the actual property. Cool trick :)
