Question

I’m learning how to use Supported Orientations to change values or texts in a textblock. What I want is that when the device is tilted to landscape mode, the textblock should display “Bye” and when it is tilted to portrait mode, it should say “Welcome”

I want to know what relational operators should be used inside the if() statement so that it gives the correct output.

What should I use inside if()?

1. if(Orientation.Equals(SupportedOrientation.Portrait)) { // display "Welcome"}
2. if(SupportedOrientation.Equals(SupportedPageOrientation.Portrait)) {// display "Welcome"}

How can I use orientation to change any values I want?

Answer 1

you can use either the OrientationChanged event of the PhoneApplicationPage class, or override the OnOrientationChanged method if you’re writing code in your page class.

this.OrientationChanged += new EventHandler<OrientationChangedEventArgs>(MainPage_Orientationchanged)

void MainPage_OrientationChanged(object sender, OrientationChangedEventArgs e)

  {
     if (orientation == PageOrientation.LandscapeLeft ||
     orientation == PageOrientation.LandscapeRight)

  {

    textblock.text = bye;

  }

if (orientation == PageOrientation.PortraitLeft ||
     orientation == PageOrientation.PortraitRight)

{

    textblock.text = welcome;
}

 }
