Question

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:

 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;
        } 

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?

If I want to turn it dynamic?

The reason that is isn’t working is because you instantiate a new radio button called rb1. If there is already an rb1, then you can try this:

Try:

private void rb1_Checked(object sender, RoutedEventArgs e)
    {

        if (rb1.IsChecked == true)
        {
            this.rb2.Visibility = Visibility.Visible;
        }
        else if (rb1.IsChecked == false)
        {
           this.rb2.Visibility = Visibility.Collapsed;
        }
