Good day
 

Good day

I am trying to add a list of question and answers to my xaml by using a string form code behind (xaml.cs), the textblock is working fine but when i try to implement for the radio buttons i keep getting these errors

"Error 1 'System.Windows.Controls.RadioButton' does not contain a definition for 'Text' and no extension method 'Text' accepting a first argument of type
'System.Windows.Controls.RadioButton' could be found (are you missing a using directive or an assembly reference?) "

xaml

<Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0">
<TextBlock x:Name="lblQuestion" Height="50" TextWrapping="Wrap" Margin="0,10,0,547"/>
<RadioButton x:Name="radA" Margin="0,65,0,492"/>
