[Enhancement] Implement UpdateSourcetrigger

Description

The UpdateSourcetrigger of Binding is extremely useful, please implement it in MAUI as in WPF.

Public API Changes

Adding a new binding attribute - I don't see it would be a breaking change.

Intended Use-Case

The UpdateSourcetrigger of Binding is extremely useful, please implement it in MAUI as in WPF.

I find it especially useful when validation is needed on user entered data (like when a number is being entered) before allowing the data to update the binding source.

And of course it would make migration from WPF or WinUI a bit easier (you can always code around this lack, but it's tedious to do so).

We've moved this issue to the Future milestone. This means that it is not going to be worked on for the coming release. We will reassess the issue following the current release and consider this item at that time.

Thanks, the lack of UpdateSourcetrigger was an annoying absence in Xamarin Forms which made migrating from Windows Phone or WPF a bit more painful. It's certainly possible to code around it but I'd rather not have to!

What happened with this ? Still not present on year later.

Any news on this? If not, what is the proper way to prevent binding failures due to incomplete input into an Entry field?
