Unknown member 'UpdateSourceTrigger' on element 'Binding'

I'm currently trying out C++/CX and XAML as a Windows 8 App - Project. It looks like things are working out great, but right now I stumbled on this error: 'Unknown member 'error WMC0011 UpdateSourceTrigger' on element 'Binding'.

I'm trying to use the UpdateSourceTrigger on a TextBox with the value 'PropertyChanged' to update the source after every keystroke like this:

<TextBox Text="{Binding Bord.Naam, UpdateSourceTrigger=PropertyChanged, Mode=TwoWay}"  Grid.Row="0" Grid.ColumnSpan="2"/>

Anyone knows how I'll be able to update the source after every key stroke?

Thanks in advance!

Solution

  • Windows 8 development does not support UpdateSourceTrigger. This is supported in Windows 8.1 apps, if you upgrade your App to 8.1 you will be able to use it.
