Cell Spanning in Windows Store App


In this article I describe how to create a Windows Store App for Cell Spanning using JavaScript. The custom template function "MyCellSpanningJSTemplate", uses the "type" field to style each item in its proper size. A "groupInfo" property must be provided on the layout of the List View to enable cell spanning.

I assume you can create a simple Windows Store App using JavaScript; for more help visit Simple Windows Store Apps using JavaScript.

To start the creation of the app, add one JavaScript page by right-clicking on the js folder in the Solution Explorer and select "Add" > "New item" > "JavaScript Page" and then provide an appropriate name. In the same way, add a HTML page to your project.


Write the following code in the default.html

<!DOCTYPE html>



    <meta charset="utf-8" />


    <link rel="stylesheet" href="//Microsoft.WinJS.1.0/css/ui-light.css" />

    <script src="//Microsoft.WinJS.1.0/js/base.js"></script>

    <script src="//Microsoft.WinJS.1.0/js/ui.js"></script>

    <link rel="stylesheet" href="/css/default.css" />

    <script src="/js/default.js"></script>


<body role="application">

    <div id="rootGrid">

        <div id="content">

            <h1 id="featureLabel"></h1>

            <div id="contentHost"></div>





Write the following code in the default.js

(function () {

    "use strict";

    var appTitle = "";

    var page = [

        { url: "page.html" }


    function activated(eventObject) {

        if (eventObject.detail.kind === Windows.ApplicationModel.Activation.ActivationKind.launch) {

            eventObject.setPromise(WinJS.UI.processAll().then(function () {

                var url = WinJS.Application.sessionState.lastUrl || page[0].url;

                return WinJS.Navigation.navigate(url);




    WinJS.Navigation.addEventListener("navigated", function (eventObject) {

        var url = eventObject.detail.location;

        var host = document.getElementById("contentHost");

        host.winControl && host.winControl.unload && host.winControl.unload();


        eventObject.detail.setPromise(WinJS.UI.Pages.render(url, host, eventObject.detail.state).then(function () {

            WinJS.Application.sessionState.lastUrl = url;



    WinJS.Namespace.define("App", {

        appTitle: appTitle,

        page: page


    WinJS.Application.addEventListener("activated", activated, false);



Write the following code in the page.html

<!DOCTYPE html>




    <link rel="stylesheet" href="/css/scenario4.css" />

    <script src="/js/script.js"></script>



    <div data-win-control="App.ScenarioInput">


    <div data-win-control="App.ScenarioOutput">

        <div id="listView"



                itemDataSource: myCellSpanningData.dataSource,

                itemTemplate: MyCellSpanningJSTemplate,

                selectionMode: 'none',

                tapBehavior: 'none',

                swipeBehavior: 'none',

                layout: {

                    groupInfo: groupInfo,

                    type: WinJS.UI.GridLayout







 Write the following code in the script.js

var MyCellSpanningJSTemplate = WinJS.Utilities.markSupportedForProcessing(function MyCellSpanningJSTemplate(itemPromise) {

    return itemPromise.then(function (currentItem) {

        var result = document.createElement("div");

        result.className = currentItem.data.type;

        result.style.overflow = "hidden";

        var image = document.createElement("img");

        image.className = "regularListIconTextItem-Image";

        image.src = currentItem.data.picture;


        var body = document.createElement("div");

        body.className = "regularListIconTextItem-Detail";

        body.style.overflow = "hidden";


        var title = document.createElement("h4");

        title.innerText = currentItem.data.title;


        var fulltext = document.createElement("h6");

        fulltext.innerText = currentItem.data.text;


        return result;



(function () {

    "use strict";

    var page = WinJS.UI.Pages.define("page.html", {

        ready: function (element, options) {





var groupInfo = WinJS.Utilities.markSupportedForProcessing(function groupInfo() {

    return {

        enableCellSpanning: true,

        cellWidth: 310,

        cellHeight: 80



var myCellSpanningData = new WinJS.Binding.List([

        { title: "Employee", text: "Employee", picture: "images/1.jpg", type: "smallListIconTextItem" },

        { title: "Employee", text: "Employee", picture: "images/2.jpg", type: "mediumListIconTextItem" },

        { title: "Employee", text: "Employee", picture: "images/3.jpg", type: "largeListIconTextItem" },

        { title: "Employee", text: "Employee", picture: "images/4.jpg", type: "mediumListIconTextItem" },
