Share Text in between Windows 8 Metro Application using Share Contract

Two Metro applications can shared the content between them using Share Charm. Content can be as simple as text or may be image or a file. In content sharing, the application that shares content is called as Source Application and the application that receives content is called as Target Application. Source Application and Target Application need to declare the type of content; they are intent to share in a Declaration.

Declaration can be configured in the package.appmanifest file. Click on package.appmanifest file and then select Declaration tab. From the Available Declarations drop down select Share target and check SupportedAnyFile Type in Supported File Types. See the image below.


Source Application

After configuring the declaration we need to write the code to share relevant text. Let us put a button and click event of that button we will share the text.


In code behind attach click event to button and call bellow function


Function to share text is as following. User can share the text from the Share Charm. Note that in the code below, we have explicitly displayed the Share charm by calling function showShareUI.

function ShowandShareContract() {

 var dataTransferManager = Windows.ApplicationModel.DataTransfer.DataTransferManager.getForCurrentView();
 dataTransferManager.addEventListener("datarequested", function (e) {
 var request = e.request; = "Debugmode"; = "Debugmode Share App";"Hello from DebugMode App");

The actual data sharing happens in the datarequested event handler. We are sharing the text “Hello from DebugMode App “

Target Application

Now let us create an application, which can consume the shared text. An application can be launched in multiple ways; we need to first check whether the application was launched as Share Target or not before accepting any data.


We also need to check whether shared operation is containing text or not. That can be check as following


Below is the code required to read the text shared and display in an output div.

 if (args.detail.kind === Windows.ApplicationModel.Activation.ActivationKind.shareTarget) {

 var shareOperation = args.detail.shareOperation;
 if ( {
 var SharedText = " Title : " +;
 SharedText = SharedText + " Description : " +;
 document.getElementById("outputDiv").innerText = SharedText;



In this way text can be shared between source application and target application using shared contracts. When you run the source application, you will get a ShareContent button. On clicking of the button Share Charm will get displayed. You will get list of all applications can act as Target Application. For example Mail application can also act as Target Application.


Let us choose target application we created. Click on ShareContreactTarget application. You can see two applications can run side by side and text from source application is displayed in output div of target application.


In this way we can share Text between two metro applications. 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.


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


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


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


Step 2: Create ListView

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


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.


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.


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


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


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


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


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


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.


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


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


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


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


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


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.


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.


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


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


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



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.


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


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


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


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.


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


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.


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.


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


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


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.


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.

Consuming WCF SOAP Service in Windows 8 Metro Application

In this post we will consume WCF SOAP Service in C#/XAML based Metro Application. This is level 100 post showing basic steps to create simple WCF Service and consume that in Metro Application.

Very first let us create a WCF Service using VS2012. Form File menu create a new project by choosing WCF Service Application project template from WCF tab.


Remove all the default code from IService1.cs and replace it with following code. In below service contract we are going to return a simple greeting message. From client a name as string will be input to the service and service will return a greeting message as string.


using System.ServiceModel;
namespace ServiceToConsumeinMetro
 public interface IService1

 string GreetingMessage(string name);



Service is implemented as following. It is concatenating two string and returning it .


namespace ServiceToConsumeinMetro

 public class Service1 : IService1
 public string GreetingMessage(string name)
 return "Welcome to Metro Word " + name;

We will go with the default binding and will not configure anything in Web.Config. Leave Web.config as it is and press F5 to run and host created WCF service in local server. On successful running in your browser you should have below output.


Now let us create a Metro Application to consume this service. From File menu in VS 2012 choose Blank App project template from Windows Metro Style tab.


Next let us design the page. On the page we are going to put one TextBox, One Button and one TextBlock. User will enter Name in textbox and on the click event of the button service will be called. Returned output from service will be displayed in the textblock. Xaml is as following



<Grid Background="{StaticResource ApplicationPageBackgroundThemeBrush}">
 <RowDefinition Height="200" />
 <RowDefinition Height="200" />
 <RowDefinition Height="200" />
 <TextBox x:Name="txtName" Margin="286,25,583,113" />
 <Button x:Name="btnCallService" Content="Enter Name above and touch to call service" Height="100" Width="364" Grid.Row="1" Margin="367,10,0,90" Click="btnCallService_Click_1"/>
 <TextBlock x:Name="textResult" Grid.Row="2" FontSize="30" FontWeight="Bold" />

Next we need to add Service Reference in the Metro project. For that right click on Metro Application project Reference tab and select Add Service Reference


Add the reference as following. My metro application name is App1. If your Metro application name is XYZ then you will be adding XYZ.ServiceReference1 provided you have not changed reference name while adding it.


In Metro word everything is asynchronous. So we need to make async call to service. When you add reference automatically visual studio creates async function for you.


We can call this function from service as following


If you notice we have put await keyword before making a call to service. Since service is called in await manner so the function inside which we are calling service must be async. On click event of the button service can be called as following


Combining all discussion together code behind will look like as following

using Windows.UI.Xaml;
using Windows.UI.Xaml.Controls;
using Windows.UI.Xaml.Navigation;
using App1.ServiceReference1;

namespace App1

 public sealed partial class MainPage : Page
 public MainPage()

protected override void OnNavigatedTo(NavigationEventArgs e)

private async void btnCallService_Click_1(object sender, RoutedEventArgs e)
 Service1Client proxy = new Service1Client();
 string result = await proxy.GreetingMessageAsync(txtName.Text);
 textResult.Text = result;

On running you should be getting output as following


I am sorry for poor UI experience but any way making UI immersive was not purpose of this post. I hope now you know basic steps to consume WCF SOAP service in metro application.

Migrate HTML5 WinJS Metro Application project to VS2012

In this post we will migrate a Metro Project created in HTML5 and WinJS from VS11 to VS2012 RC.

Recently I upgraded my system to Windows 8 Release Preview. After upgrading Windows, I migrated VS to VS2012 RC. After successful installation of VS2012, I tried opening a HTML5 + WinJS project created in VS11. When I tried to build that project, I got below exception.


Exception was in file C:\Windows\Microsoft.NET\Framework\v4.0.30319\Microsoft.Common.targets

To remove this error what all you need to do is go to solution and remove old reference of Microsoft.WinJS


And then again try to rebuild the solution. You should not be getting any build error. Though after than if you run the project you will be getting errors like


This error implies that reference has been missing. To solve this we need to add new reference in the project. Add Windows Library for JavaScript 1.0 RC reference in the project. image

After adding reference you need to change the references on HTML. Currently your reference may look like as following


You need to change Microsoft.WinJS.0.6 to Microsoft.WinJS.1.0.RC. After changing references should look like as following


No go ahead and run the project. You should be not getting any error. In this way you can migrate HTML5 WinJS Metro project to VS2012.

I hope this post is useful. Thanks for reading.
