Making a WPF TextBox binding fire on each new character?
Solution 1:
In your textbox binding, all you have to do is set UpdateSourceTrigger=PropertyChanged.
Solution 2:
You have to set the UpdateSourceTrigger property to PropertyChanged
<TextBox Text="{Binding Source={StaticResource fileLister}, Path=Path, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"
Height="25" Margin="12,12,12,0" VerticalAlignment="Top"/>
