WinJS winControl is undefined RRS feed

  • Question

  • Here is my code,

     var item = document.getElementById("view-zoomedin");
                var zoomedInView = document.getElementById("view-zoomedin").winControl;
               zoomedInView.addPage("/pages/Content.html", "Content");

    in here console.log items are displaying and zoomedInView returns null(document.getElementById("view-zoomedin").winControl  is undefined ) . Why? How to fix it.

  • OK, how have you defined your "view-zoomedin" in the HTML markup? Is it even a WinJS control to begin with? See this link for more info: http://msdn.microsoft.com/en-us/library/windows/apps/Hh770814.aspx

  • You must first declare your control in HTML or JavaScript. For example  A listview control declared in HTML is:

    <div id="myPageControl" data-win-control="WinJS.UI.ListView"></div>

    Then you can access its controls in javaScript like this

    var myPageControl = document.getElementById("myPageControl").winControl;
    myPageControl.itemDataSource = dataSource;
