Page content cannot show while keyoboard is swipe up and scrolling on screen

Hi,

I have created app using Xamain.Forms 1.3.4.

I have textbox at the end of screen. When I tap on textbox the keyboard swipe up and content of screen gets up. While I am scrolling up and down the page content when keyboard is on I cannot able to see the top content and some sort of content I can see.

Can you please help what to do here that can show whole page with all content even if keyboard is swipe up?

Thanks
