Per page/per view Culture

[sjordanGSS]

Hi All,

I've recently come across a requirement to have a specific page or set of views using a different culture to the main app. What I'd like to do is to change the culture (specifically currency formatting) without affecting the global culture. Is there a way to do this in Xamarin.Forms? I've worked around this by doing the formatting in the viewmodel and exposing this to the UI as bindable string properties, but since I also need to use the value itself for view logic it means I've got 2 properties containing the same data in different formats, which isn't brilliant. I'd much rather make use of Binding.StringFormat to take care of currency formatting, but I don't know of any way to do this without changing the culture for the entire app. I'd appreciate any insights or pointers into how I might accomplish this, if it is at all possible. Thanks!

EDIT I'm also interested in whether there would be any difference in acheiving this between Xamarin.Forms and MAUI.

Coming back to this after seeing #11815 and it got me wondering if we could set the culture per binding expression, something like

Text="{Binding Value, Culture='en-GB', StringFormat='{0:C}'}"

to find a built-in culture with the given specifier (in this case, British English) and use it to format Value as currency would be quite nice, or

Text={Binding Value, Culture={StaticResource customCulture}, StringFormat='{0:C}'}"

to allow the use of a custom culture. Leaving the property unset obviously uses CurrentUICulture.

Huh, turns out there are already tickets open for this feature in X.F and Maui repos: dotnet/maui#5696. I guess I can get some sense of validation that they are suggesting the exact same usage as I have here, so that's something.
