How to suppress an Hardware Backbutton event in WinJS for Mobile App?

Question

There are no default methods like, event.stopPropogation() or preventDefault(). How do I stop the default behaviour of the event(Hardware Backbutton)?!

Answer 1

Here is the solution.

var app = WinJS.Application;

app.onbackclick = function (evt) {

    // Code that handles event ...

    // Need to return true to cancel the default behavior of this event.
    return true;
}
