Popup V2 return data

[filippomoretto]

From https://github.com/CommunityToolkit/Maui/wiki/Migrating-to-Popup-v2#popupoptions I read:

Removed the need to subclass Popup
You can now use any View as the popup content without needing to inherit from Popup. The only caveat to this rule is - if you need to return a result from the popup, you have to inherit from Popup.

To return data I need to inherit from Popup<TData> but how can I specify in xaml that the base class is Popup<T> and not Popup?
Have I to create MyPopup : Popup<T> without xaml and a separate view to write the content in xaml?

I tried to specify, for example, x:TypeArguments but I got "Partial declarations of 'MyPopupView' must not specify different base classes". Popup and Popup<T> have the same namespace, so could be this the problem?

It would be a lot easier to see your code but you are correct to use x:TypeArguments you must make sure that the .xaml.cs file also has its type defined as Popup, replacing T with your actual type.

You can see how we have done this here https://github.com/CommunityToolkit/Maui/blob/main/samples/CommunityToolkit.Maui.Sample/Views/Popups/ReturnResultPopup.xaml and with its associated C# file

My bad, silly me. I wrote xmlns:system="clr-namespace:System;assembly=System.Runtime" wrong🤦🏻😢
Ok, it works; I can try to complete the migration to Popup V2.
Thank you
