Create App Package for Windows Store

 

 

In this post we will follow step by step procedure to create app package for Windows Store. Let us suppose you have created a “Hello World “application for Windows Store and want to create an App Package for the same. To create that from menu select PROJECT

 

image

 

From the POROJECT menu, select Store->Create App Package

 

image

 

Next you will get Create App Package wizard. At the point, we do not want to upload package to Windows Store so select the option No and click on Next

 

image

 

In next screen you need to choose Platform for the package. You can create package for

 

  1. 64 bit platform
  2. 32 bit platform
  3. ARM
  4. Neutral platform

 

Subsequently you need to choose whether you want to create package for Release Mode or Debug Mode. Here, I am creating a package for Neutral platform. Select that option and click on Create to create package.

 

image

 

After clicking on create in bottom of Visual Studio you can notice Build Succeeded message. And in next window you will get Success Message with path of the created package.

 

image

 

When you browse to path you will find package has been created to upload.

In this way you can create application package for Windows Store. I hope you find this post useful. Thanks for reading.

 

Netflix Movie Explorer a Metro Application: Creating Step by Step

Download source code of this article from here

In this article we will follow step by step approach to create Netflix Movie Explorer Metro Application. We will use HTML and WinJS to create this application. See the video to understand expected behavior of the application.

Some of the features of application are as following

  • Browse movies from Netflix
  • Rate the Movies
  • Browse movies in Semantic views
  • Share the Rating of a particular movie with social media or via mail

To get it started, launch Visual Studio and create a new project by choosing Blank App Project template from Windows Metro Style tab. You need VS12 to create this application.

image

After creating project in default.html change “content goes here “with following

clip_image001

After that follow the steps as below,

Step 1: Create Data Source

Very first we need to create data source by reading JSON data from OData feed of Netflix movie database. That can be done using WinJS.xhr function

image

In above code snippet, we are performing following tasks

  • Making a call to Netflix OData using WinJS .xhr function
  • As input parameter to xhr function, we are passing exact url of OData Endpoint.
  • We are applying projection and providing JSON format information in URL itself.
  • Once JSON data is fetched form Netflix server data is being parsed and pushed as individual items in the WinJS list.

After fetching, data is being parsed using JSON Parser and individual items are pushed to movieArray. movieArray is defined as following

image

Step 2: Create ListView

After creating data source we need put WinJS ListView control on the page.

image

A HTML div can be converted to WinJS ListView by setting data-win-control attribute to WinJS.UI.ListView. Other options can be set like layout of the ListView. In this case we have set it to GridLayout, so data will be displayed horizontally. ListView needs data source to display data. Data source can be set either in HTML or in code behind. Let us set data source of movieListView to the movieArray.

image

Make sure that you are setting data source of ListView after the WinJS.xhr function call. At this point of time if you go ahead and run the application, you should be getting following output.

image

Step 3: Create ListView Template

In above output, data is in raw form. To make data more immersive and to show the way we want, we need to create template out of data. After creating template, it needs to be set as attribute of ListView. Template can be created as following

image

Template can be created by setting data-win-control attribute of HTML div as WinJS.Binding.Template . Inside div element

  • Binding image to Picture property of WinJS List or Array
  • Binding inner text of h4 element to Title property of WinJS List or Array

Once Template is created, it needs to be attached to the ListView. After attaching Template, ListView will be as following

image

No go ahead and run the application, you should be getting following shape of the application

image

Before we move ahead, let us put some CSS on ListView to make it more immersive

image

After applying styles on List View, your application should be in following shape.

image

Step 4: Grouping of DataSource

Next we want to group the movies as per first character of their title. For that create group functions as following.

image

After creating grouped functions, we need to create grouped item list and set it as itemDataSource of List View. Modify setting of ListView data source as following

image

Let us go ahead and run the application. At this point shape of the application should be as following

image

Step 5: Creating Header Template

Above we can see the header data is in raw form. So to make header information more immersive, you need to create template for header and then attach that to ListView

A header template can be created in same way as of item template. Header template is created as following

image

After creating Header Template, we need to attach this to ListView. So ListView will be modified as following

image

Let us go ahead and run the application. At this point shape of the application should be as following

image

Step 6: Adding Semantic Zoom

Next we need to add sematic zoom to the ListView. For that very first let us create a Semantic Zoom Template. We want to display movies with first letter of title in semantic zoom view.

image

After creating Semantic Zoom View template, we need to add a SemanticZoom WinJS control. Inside the Semantic Zoom control we need to put ListView (created in previous steps) and a Semantic Zoom View. We can put that as following.

image

After adding Semantic Zoom view we need to set data source of it. This can be set as following.

image

Last work we need to do in Semantiz Zoom is to apply styles.

image

Let us go ahead and run the application. At this point shape of the application should be as following

image

image

Step 7: Adding Output DIV

Now we need to add code to add output div. When user will select a particular movie detail of that movie will be displayed in the output div for rating.

image

And in code behind on the touch of a particular ListView item, we need to display that information in output div. For that add the following code in code behind

image

In above code snippet

  • Iteminvoked event is attached to the ListView
  • When item is invoked then itemPromise function is being called with parameter invokedItem
  • On the invokeditem data we can fetch attributes of ListView items
  • In last set the vales of HTML elements from selected items data.

Let us go ahead and run the application. At this point shape of the application should be as following

image

Step 8: Adding Rating control

To allow user for Rating, let us go ahead and add a WinJS Rating control. Rating control can be added as following

image

We can create a Rating control by setting data-win-control attribute of a div as WinJS.UI.Rating. Other data options like maxRating and averageRating can be set in data-win-options attribute.

After adding Rating control, we need to write code to allow users to perform rating.

image

Let us go ahead and run the application. At this point shape of the application should be as following

image

Step 9: Adding Code to Share Contract

We want our user should able to share the rating of movie on other applications like Mail, Twitter, Facebook. For that we will have to use ShareContract.

image

In above code we are getting the request and setting the title and description in data property. After that creating text to share and setting it in the data request. Above is the code to simple text sharing via ShareContract feature of Windows 8. Once we have share function is ready, we need to get the current view of application using DataTransferManager.getForCurrentView () and attach and event handler datarequested on same. When datarequested event will be fired ShowandShareContract function (created above) will be called and user will able to share using Share Charm.

image

Put above code just before ProcessAll() function and do not forget to declare following variable globally

image

Let us go ahead and run the application. At this point shape of the application should be as following. This is our final application.

image

In this application user can browse the movies, rate a particular movie and then share the rating with the friends on social media or mail.

Conclusion

In this post we learnt to create a Metro Application from scratch. Even though you can download source code of this article from here , I am sharing the codes below . Feel free to use them as you required.

How to fetch selected item of ListView in HTML based Windows 8 Metro Application

I had tough time get the value of selected item of a ListView. So in this post I am sharing the code snippet required to fetch selected item from the ListView.

Read this article for ListView Binding with Grouping and Semantic Zoom in Windows 8 JavaScript Metro Application

I strongly suggest you to read the above article for more detail on ListView. If you continue with above article and want to get the value of selected item you can do that as below,


lstMovies = document.getElementById("movieListView").winControl;  
lstMovies.addEventListener("iteminvoked", function (e) {
                e.detail.itemPromise.then(function (invokedItem) {


                    var titleOfData = invokedItem.data.title;
                    var selecteplayerImg = invokedItem.data.picture;
                });
            }, false);


In above code snippet

  • lstMovies is name of the ListView.
  • Iteminvoked is name of the event. This event gets fire when an item in the ListView is being selected.
  • There are two data bind to the List View item. They are Title and Picture. Any data can be fetched as following snippet. invokedItem is parameter of itemPromise.

image

Title and Picture are properties of the datasource bind to the ListView.

In this way you can fetch selected item from ListView in HTML based Windows 8 Metro Application. I hope this post is useful. Thanks for reading!
