How to bind the x:Uid of a TextBlock in XAML? - xaml

Question

I am making a menu that can display many languages so I want to set the Uid of these TextBlock on each item, how can I set the Uid of a TextBlock in XAML through data binding. Because when I set x:Uid="{Binding Label}", the IDE shows that is an error. Please help me, thank you!

Answer 1

The binding is used Text="{Binding Label}", when you want value to be fetched from viewmodel. Drawback you will have to handle according to language the conversion of text.
x:Uid is supposed to be specified inside Strings->en_US folder. You create a resource file by default Resources.resw file inside it you add Name lets say Sample.Text and its Value as Your Text.
Inside your XAMl you are supposed to use x:Uid="Sample".
Now as per your requirement when you add more language using multilingual toolkit it would handle conversion for required language and on uploading to store it would select the particular language from app package and hence user views the app in the particular language they have selected on their device.

Answer 2

If you want to use the translation from strings folders you can instead of binding to the x:Uid value, bind the Text variable to a text key and use a value converter and find the translated text in code behind.
So the Xaml will look something like:
<TextBlock Text="{Binding Label, Converter={StaticResource TranslatorConverter}}"/>
Then you need the value converter:
public class TranslatorConverter : IValueConverter
{
public object Convert(object value, Type targetType, object parameter, string language)
{
var resourceLoader = Windows.ApplicationModel.Resources.ResourceLoader.GetForCurrentView();
return resourceLoader.GetString(((String)value)); ;
}
public object ConvertBack(object value, Type targetType, object parameter, string language)
{
throw new NotImplementedException();
}
}
The "Label" in your Resources.resw file shall then simply be without the ".text" part that you use when using the x:Uid binding.
However if the multilingual toolkit as suggested is easier or not I don´t know. I have not used the multilingual toolikt.
