    If you just want to get something working quickly you can use the messagecenter to pass the value back to the calling view model (assuming your using binding and MVVM pattern). Even if your not, you can pass messages between pages with the value you want to return.

    I'm not saying this is the recommended approach, it's just a suggestion to get something working quickly if your starting out with Forms.

    As I mentioned, the message center is just a quick way to do this and does have drawbacks you have to be aware of if you have multiple instances of pages open.

    There's a blog post here from @adamkemp which shows a decoupled way of doing this.
