Problem with DatePicker inside PickerBox

[Martin]

When I create full screen PickerBox, I add Datepicker in it, start the app, open picker box, open date picker and click Back button, then I get black screen - both date picker and picker box closes, but somehow I can't see anything now.

When I click back again, I am back at the main page. 

I guess there is problem with handling the Back button when nested picker is inside PickerBox. How to solve this? Is it possible to somehow capture the Back button propagation?

For reproducing this just add 

<telerikInput:RadDatePicker /> inside the PickeBox sample in Examples project.

Hi Martin,

Thanks for writing.
Since both RadPickerBox and RadDatePicker use RadWindow internally, a window is opened inside another window. This is a bad user experience and is therefore discouraged when developing for windows phone. RadWindow does not support windows in windows which is why you are experiencing this behavior.

Please reconsider your application flow so that it does not use windows inside windows.
Thank you for understanding.

Hi Victor, I can see that the DatePicker inside a RadCalendar control (when tapping the header) inside a PickerBox works fine with back button press. However, when I try to implement a custom DatePicker (instead of the one inside RadCalendar control) inside a PickerBox, I got problems with back button.

How is it possible in the RadCalendar control?

Hello,

Using a control that displays popup from within another popup is scenario that is not supported and not recommended on Windows Phone. Our recommendation is to chose another approach to accomplish the needed results.
