Introduction

In this article I describe how to create a Windows Store App for switching from a Grid to a List using JavaScript. This app demonstrates how to switch layouts within the ListView. To ensure that your items are correctly sized ensure that they are smaller than 302px.

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>

<html>

<head>

<meta charset="utf-8" />

<title></title>

<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>

</head>

<body role="application" style="background-color:lightgoldenrodyellow">

<center><div id="rootGrid">

<div id="content">

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

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

</div>

</div>

</center>

</body>

</html>

Write the following code in the default.js

(function () {

"use strict";

var appTitle = "";

var pages = [

{ 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 || pages[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();

WinJS.Utilities.empty(host);

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,

pages: pages

});

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

WinJS.Application.start();

})();


Write the following code in the page.html

<!DOCTYPE html>

<html>

<head>

<title></title>

<link rel="stylesheet" href="/css/page3.css" />

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

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

</head>

<body>

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

<button id="swapLayoutButton" class="action">Switch to list</button>

</div>

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

<div id="smallListIconTextTemplate" data-win-control="WinJS.Binding.Template" style="display: none">

<div class="smallListIconTextItem">

<img src="#" class="smallListIconTextItem-Image" data-win-bind="src: picture" />

<div class="smallListIconTextItem-Detail">

<h4 data-win-bind="innerText: title"></h4>

<h6 data-win-bind="innerText: text"></h6>

</div>

</div>

</div>

<div id="listView"

class="win-selectionstylefilled"

data-win-control="WinJS.UI.ListView"

data-win-options="{ itemDataSource: myData.dataSource,

itemTemplate: smallListIconTextTemplate,

selectionMode: 'multi',

tapBehavior: 'none',

swipeBehavior: 'select',

layout: { type: WinJS.UI.GridLayout }

}"

></div>

</div>

</body>

</html>


Write the following code in the script.js

(function () {

"use strict";

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

ready: function (element, options) {

var listView = element.querySelector("#listView").winControl;

listView.forceLayout();

function swapLayout() {

if (listView.layout instanceof WinJS.UI.GridLayout) {

listView.layout = new WinJS.UI.ListLayout();

WinJS.Utilities.toggleClass(listView.element, "listLayout");

element.querySelector("#swapLayoutButton").innerText = "Switch to grid";

WinJS.log && WinJS.log("You switched to List layout!", "app", "status");

} else {

listView.layout = new WinJS.UI.GridLayout();

WinJS.Utilities.toggleClass(listView.element, "listLayout");

element.querySelector("#swapLayoutButton").innerText = "Switch to list";

WinJS.log && WinJS.log("You switched to Grid layout!", "app", "status");

}

}

element.querySelector("#swapLayoutButton").addEventListener("click", swapLayout, false);

}

});

})();

var myData = new WinJS.Binding.List([

{ title: "Tea", text: "Tea", picture: "/images/1.jpg" },

{ title: "Tea", text: "Tea", picture: "/images/2.jpg" },

{ title: "Tea", text: "Tea", picture: "/images/3.jpg" },

{ title: "Tea", text: "Tea", picture: "/images/4.jpg" },

]);
