Windows Phone应用程序栏上的单选按钮？

Question

Hey guys I have this page :

PS: this is temp data, so it don't look so good ;P

Now if I click on that filter button, I want a popup window or radio buttons to show in the application bar, is that even possible? Or should I try another way of doing this?

As you choose a radio button I am going to have the page filter on the choice made, so I can't leave the page to go make a choice. Any help/link/tutorial will be appreciated :)

Thanks in advance,

You can't have a radio button in the app bar.

I would implement this as a separate page and update your filter when you navigate back to this page. The page instance and view model will be still in memory so it should be a matter of detecting the back navigation in OnNavigatedTo and applying your filter at that point. Sharing a ViewModel between this page and your filter page would be the best way of communicating the filter value, but that's not the only way.
