Detail List View in Windows Store App

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.html:

<!DOCTYPE html>

<html>

<head>

</head>

</div>

</div></center>

</body>

</html>

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:

<!DOCTYPE html>

<html>

<head>

</head>

<body>

</div>

</div>

<div id="listView2"

class="win-selectionstylefilled"

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

data-win-options="{

itemDataSource: myNewsData.dataSource,

itemTemplate: mediumListIconTextTemplate,

selectionMode: 'multi',

tapBehavior: 'directSelect',

layout: { type: WinJS.UI.ListLayout }

></div>

</div>

</body>

</html>

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);

});

}

});

})();

Output:
