Introduction
In this article I describe how to create a Windows Store App for Detail List View using JavaScript. This app shows how to use the List View to create a detail list, similar to what you'd see in most news screens. The List View provides a list of news. Selecting an item in that list updates the bottom pane.
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 two JavaScript pages 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 one HTML page to your project.

Write the following code in 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 page.html:

<h2 id="inboxNews_Text"></h2>
<h6 id="inboxNews_Title"></h6>
<div id="inboxNews_Body"></div>
</div>
</div>
</div>

Write the following code in script.js:
var myNewsData = new WinJS.Binding.List([
{ title: "Sports News", text:"Deepak Arora", picture: "images/1.jpg" },
{ title: "Wheather News", text:"Deepak Arora", picture: "images/1.jpg" },
{ title: "Politics New ", text:"Deepak Arora", picture: "images/1.jpg" },
{ title: "World news", text:"Deepak Arora", picture: "images/1.jpg" }
]);
(function () {
"use strict";
var page = WinJS.UI.Pages.define("page.html", {
ready: function (element, options) {
var NewsTitle = element.querySelector("#inboxNews_Title");
var NewsText = element.querySelector("#inboxNews_Text");
var NewsBody = element.querySelector("#inboxNews_Body");
var listView = element.querySelector("#listView2").winControl;
listView.forceLayout();
function selectionChangedHandler() {
var selectionCount = listView.selection.count();
if (selectionCount === 1) {
listView.selection.getItems().done(function (items) {
inboxNews_Title.innerText = "From: " + items[0].data.text;
inboxNews_Text.innerText = items[0].data.title;
inboxNews_Body.style.color = "black";
inboxNews_Body.innerText = "\n\nNews Body";
});
} else {
inboxNews_Title.innerText = "";
inboxNews_Text.innerText = "";
inboxNews_Body.style.color = "green";
if (selectionCount > 1) {
inboxNews_Body.innerText = "Multiple Newss are selected!";
} else {
inboxNews_Body.innerText = "No News selected!";
}
}
}
listView.addEventListener("selectionchanged", selectionChangedHandler, false);
listView.itemDataSource.getCount().done(function (itemCount) {
var initialSelection = (itemCount > 0) ? 0 : [];
listView.selection.set(initialSelection);
});
}
});
})();
