Popup with an Entry or Pickup in it goes off screen when KB comes up

[imsam67]

Current Behavior

If I place an Entry or Picker control in a Popup, as soon as the soft keyboard shows up, the Popup goes off screen.

This was working fine before when the app was targeting .NET 7 and the previous version of CommunityToolkit.Maui. To see what maybe causing the issue, I downgraded CommunityToolkit.Maui to 6.1.0 and the app still targeting .NET 8 and the issue persisted. I then changed the TFM to .NET 7 and the issue disappeared. So the issue seems to have someting to do with .NET 8 OR CommunityToolkit.Maui's interaction with .NET 8.

Here's what it looks like:

Expected Behavior

The Popup should just slide up as it used to.

Steps To Reproduce

1. Create a Popup in a .NET MAUI app targeting .NET 8 and using CommunityToolkit.Maui v7
2. Place an Entry control in it. BTW, a Picker control would produce the same issue. Looks like any control that opens up the keybaord would produce the same issue
3. Run the app iOS device
4. Open the Popup and tap on Entry to bring up the soft keyboard

Environment

- .NET MAUI CommunityToolkit: 7.0.0
- OS: iOS 17.1.1
- .NET MAUI: .NET 8

Anything else?

Somebody on X mentioned this and it actually works nicely as a workaround:

using Microsoft.Maui.Platform;
...
// Before we open the Popup, we "Disconnect" KeyboardAutoManagerScroll
#if IOS
            KeyboardAutoManagerScroll.Disconnect();
#endif

   var popup = new MyPopUp();
   var response = await Application.Current.MainPage.ShowPopupAsync(popup);

// Once done with the Popup, we "Connect" KeyboardAutoManagerScroll again
#if IOS
            KeyboardAutoManagerScroll.Connect();
#endif

No response

I also verified, but it did not occur in .NET 7.
This is likely due to the new scrolling feature added in .NET 8.
dotnet/maui#16784

It seems that the only way to turn off the new scrolling feature is to call the Disconnect method of the KeyboardAutoManagerScroll class.

Below are the verification results with .NET 7.
