Trigger IsVisible true- false of label on radio button checked- Uncheck in xaml - xaml

Question

I am trying to show/hide a label using Trigger on RadioButton check/uncheck but I am getting the error. I can also do it in c# code by inotifypropertychanged but i want to use Triggers and this is my first time. I am not able to understand this error.

Error

Answer 1

The TargetType should be of type Label and not RadioButton.
From triggers docs:
TargetType - the control type that the trigger applies to.
...
<Label.Triggers>
<DataTrigger TargetType="Label"
Binding="{Binding Source={x:Reference rdbEnglish},
Path=IsChecked}" Value="True">
<Setter Property="IsVisible" Value="True" />
</DataTrigger>
</Label.Triggers>
