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.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>

<body>
<div data-win-control="App.pageInput">
<button id="swapLayoutButton" class="action">Switch to list</button>

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

</div>
</div>
</div>
<div id="listView"
class="win-selectionstylefilled"
data-win-control="WinJS.UI.ListView"
data-win-options="{ itemDataSource: myData.dataSource,

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" },
