Does anybody know if this control comes with the windows phone 8 SDK or if I must program it?
This screen appears when I go to people => click + icon. There are many very similar screens in windows phone but I don't know if they're ready controls or custom ones.
What I need is a screen that hides all background and just shows a list of options upon clicking a certain button, and I want to handle application overflow depending on the option the user chose.
Any ideas?
You can use the CustomMessageBox from toolkit http://phone.codeplex.com
it takes a Content that can be a listbox or user control. and you can make it take the full screen.
