Hello,​

Welcome to our Microsoft Q&A platform!

If i write text instead {Binding Name} it appears in radio button content as expected

This is because you use property-element syntax for the Content property of the RadioButton. The BindingContext of the radioButton and the 'Content' will be different, the 'Content''s BindingContext will be null. This is why the data binding of RadioButton.GroupName property works fine, but the Content not.

Please use 'Content' property as the XML attribute instead. Change the code like below:

   <DataTemplate x:Key="RadioTemplate" x:DataType="dtoModels:PossibleAnswer">  
        <Frame Padding="10,5,10,5" CornerRadius="10" HasShadow="True">  
            <RadioButton GroupName="{Binding GroupId}" IsChecked="{Binding IsChecked}" Style="{StaticResource RadioButtonSurvey}" Content="{Binding Name}"/>  
        </Frame>  
    </DataTemplate>
