Hello,

I want to force landscape mode only on some selected views and not for the whole App.

Do you want to set landscape mode in specific ContentPage?
If so, you can invoke native platform code to implement it.

You can use Microsoft.Maui.ApplicationModel.Platform.CurrentActivity.RequestedOrientation = Android.Content.PM.ScreenOrientation.Locked; and Microsoft.Maui.ApplicationModel.Platform.CurrentActivity.RequestedOrientation = Android.Content.PM.ScreenOrientation.Landscape; to lock the page to Landcape Mode.

You can use Microsoft.Maui.ApplicationModel.Platform.CurrentActivity.RequestedOrientation = Android.Content.PM.ScreenOrientation.User; to reset it like following code.

   public class DeviceOrientationService  
       {  
           public void SetOrientation()  
           {  
   #if ANDROID  
   Microsoft.Maui.ApplicationModel.Platform.CurrentActivity.RequestedOrientation =    Android.Content.PM.ScreenOrientation.Locked;  
    Microsoft.Maui.ApplicationModel.Platform.CurrentActivity.RequestedOrientation = Android.Content.PM.ScreenOrientation.Landscape;  
   #endif  
           }  
          public void RestSetOrientation()  
           {  
   #if ANDROID  
   Microsoft.Maui.ApplicationModel.Platform.CurrentActivity.RequestedOrientation =    Android.Content.PM.ScreenOrientation.User;  
            
   #endif  
           }  
       }  

For example, you have page called page1, you need to Force Landcape Mode, you can execute deviceOrientationService.SetOrientation(); in OnAppearing method and deviceOrientationService.RestSetOrientation(); in OnDisappearing method.

   protected override void OnAppearing()  
       {  
           base.OnAppearing();  
           DeviceOrientationService deviceOrientationService = new DeviceOrientationService();  
           deviceOrientationService.SetOrientation();  
       }  
     
   override protected void OnDisappearing()  
       {  
           base.OnDisappearing();  
           DeviceOrientationService deviceOrientationService = new DeviceOrientationService();  
           deviceOrientationService.RestSetOrientation();  
       }  

I also want to have the forced landscape only ontablets not on phones.

You can use get the device type from the MAUI in app.xaml.cs. If the type is Tablet, you can forced landscape like following code.

   public App()  
       {  
           InitializeComponent();  
          MainPage = new AppShell();  
          DetectDeviceType();  
      }  
     
     
     
      private void DetectDeviceType()  
       {  
           if (DeviceInfo.Current.Idiom == DeviceIdiom.Tablet)  
                 
           {  
               Console.WriteLine("The current device is a Tablet");  
               DeviceOrientationService deviceOrientationService = new DeviceOrientationService();  
               deviceOrientationService.SetOrientation();  
           }  
                
       }
