developing an Universal App using Radical : markup not work

[massimopasquali]

Hello,
I'm developing an Universal App using Radical, so this afternoon I have tried to use this Namespace in my XMAL

xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:markup="http://schemas.topics.it/wpf/radical/windows/markup"
xmlns:behavior="http://schemas.topics.it/wpf/radical/windows/behaviors"

But I haven't been able to do that Text="{markup:EditorBinding TargetSpeed}"

can you help me, give me some suggestions?

grazie

Unfortunately the markup:EditorBinding is not supported on UWP, UWP doesn't support custom markup extensions so there is no way to provide the same functionality.
The workaround, tedious I know, is to use the standard Binding markup extension and set to true all the flags that the markup:EditorBinding sets to true:

<TextBox Text="{Binding Path=MyText, 
                        UpdateSourceTrigger=PropertyChanged, 
                        NotifyOnValidationError=True, 
                        ValidatesOnDataErrors=True, 
                        ValidatesOnExceptions=True}" />

Thanks, I have to developer an app with xamarin forms, can I use Radical with it?

Ooops. I totally missed this. The universal version should work with Xamarin as well for the ViewModel section, I suspect all what is markup simply can't work on Xamarin XAML dialect. Unfortunately my knowledge of Xamarin platform is very little.
