title: How can I use RadioButton to turn visible others RadioButtons?
body: <p>I've been trying to use a RadioButton to turn visible another. I am new to this enviroment and this is my first Windows Phone app. 
  My code:</p>
  
  <pre><code> private void rb1_Checked(object sender, RoutedEventArgs e)
      {
          RadioButton rb1 = new System.Windows.Controls.RadioButton();
  
          if (rb1.IsChecked == true)
          {
              this.rb2.Visibility = Visibility.Visible;
          }
          else if (rb1.IsChecked == false)
          {
             this.rb2.Visibility = Visibility.Collapsed;
          } 
  </code></pre>
  
  <p>Isnt working well. I am trying to do this with Windows Phone Emulator. I already found something called autopostback, is there a similar property to Windows Phone too?</p>
  
  <p>If I want to turn it dynamic? </p>
