In-Depth Information
The idea is to populate the text elements with information from the application and
pass the result to the Metro notifications system. To demonstrate this feature, I had added a
new JavaScript file to the project called tiles.js , the content of which is shown in Listing
4-4. The length of the Windows.UI.Notifications is long enough to cause layout problems for
code on the printed page, so I have created a variable called tn as shorthand and assigned the
namespace to it.
Listing 4-4. The tiles.js File
/// <reference path="//Microsoft.WinJS.0.6/js/base.js" />
/// <reference path="//Microsoft.WinJS.0.6/js/ui.js" />
(function () {
"use strict";
WinJS.Namespace.define("Tiles", {
sendTileUpdate: function () {
var tn = Windows.UI.Notifications;
var xmlFragment = tn.TileUpdateManager
var textNodes = xmlFragment.getElementsByTagName("text");
var items = ViewModel.UserData.getItems();
for (var i = 0; i < textNodes.length; i++) {
var listItem = items.getAt(i);
if (listItem) {
textNodes[i].innerText = listItem.item;
for (var i = 0; i < 5; i++) {
.update(new tn.TileNotification(xmlFragment));
var eventTypes = ["itemchanged", "iteminserted", "itemmoved", "itemremoved"];
var itemsList = ViewModel.UserData.getItems();
eventTypes.forEach(function (type) {
itemsList.addEventListener(type, Tiles.sendTileUpdate);
Notice that the first letter of the template name is lowercase. If you use an uppercase
letter, then you will get the default template rather than the one you wanted.
