Hello,

I'm trying to create an app which shows a different page on swiping left or right.
I'm using the flipview control and loading it with Page class objects.

It works well, but when I select a textbox inside, the control recieving the focus is the flipview instead of the textbox, and then the keyboard covers it.

My question is, how I should implement his UI?

Thanks!
