How to adjust screen when keyboard open in windows phone 8?

问题

I am working in Windows phone 8. In One of the pages of my app there is a LongListSelector and under it there is a TextBox. When the TextBox get focused then keyboard is opened. As the keyboard is opened then the LongListSelector is shifted up by keyboard height. If I maintain the margin of the LongListSelector by keyboard's offset then some of the items of LongListSelector go under the keyboard.

All I want to do is when keyboard is shown then margin will be updated and the previous focused item of the LongListSelector should not go under keyboard. Here I don't want to use ScrollTo() function to scroll a specific item of LongListSelector.

Any suggestion or help will be appreciated.

Here is an example of workaround. Though this code is for WP8. You will have to make some changes to make this working for WP8.1 like :

1. Tap in xaml will be replaced by Tapped.

2. ((App)Application.Current).RootFrame.RenderTransform = new CompositeTransform(); will be replaced by

   Window.Current.Content.RenderTransform = new CompositeTransform();

3. Dispatcher.BeginInvoke(() => {}will be replaced by

CoreDispatcher dispatcher = CoreWindow.GetForCurrentThread().Dispatcher; await dispatcher.RunAsync(CoreDispatcherPriority.Normal, () => {}

let me know if you face any issue.
