In Windows Phone, add a Tilt effect to the Grid

In Windows Phone, the Tilt effect is a classic effect, and we can easily add such effects to controls such as buttons (using the Tilt effect of the Windows phone Toolkit), but if we want a Grid to have a Tilt effect, , it would not work if it was written directly:

<x:name= "Gridgame"  toolkit:TiltEffect.IsTiltEnabled= "True" >

Why is it possible to write a button like this, and the grid fails?

This is because the tilt effect is only for "seleteable" items, and the Grid is not an "selecteable" Item ...

How to solve it?

The method is also very simple, a bit trickery meaning, is to put a "selectable" on the outside of the grid: ListBoxItem. The wording is this:

<toolkit:TiltEffect.IsTiltEnabled= "True">   <   x:name= "Gridgame"></Grid></ ListBoxItem >

The grid also has a tilt effect.
