Easy steps to call WCF service in Windows Phone 7

Dear All,

Today we will learn how to connect WCF service with Windows phone.

So let’s start with step by step I am using one of the best templates which Windows Phone 7 support it is data bound template.

We add WCF service project to same solution.


We have created a WCF service which returns Category Id, Category name, Category description from Games database. For this we have created a custom data contract as shown in below fig


Now we added the reference of this service to our windows phone project using add service reference menu which comes when we right click on windows phone project.

Once the service reference is added we won half battle now the next challenge is call the method of this service in our windows phone 7 projects. As you know the first step is to create an object of this service which we can do with following code.

 DataServiceFreeTips.CategoryInterfaceClient proxy = new DataServiceFreeTips.CategoryInterfaceClient();

Now all the services which we call using service reference always support asynchronous calling so.

We first create a handler which give us hint when the service get all the data to do this we write following code. And after this service call we call the actual service asynchronous method.

   proxy.GetCategoryCompleted += new EventHandler<DataServiceFreeTips.GetCategoryCompletedEventArgs>(proxy_GetCategoryCompleted);

Now we are good to go and now we will run it and see. We will get the entire category game list as shown in below fig.


In this way we can call a WCF service.

How to set Windows Phone Page orientation in 5 minutes

Dear Friends,

Today we start with some basic but important feature for Windows Phone which is Orientation of screen.  As we know windows mobile phone is handy device a user can handle it any ways like portrait or landscape. Our main aim here is to change our screen orientation according to user action. Windows phone page has two properties for this activity.

When you open the XAML of the page in the phone application page you will find SupportedOrientations and Orientation by default these properties having value Portrait.

Support Orientations can have following property

a) Landscape  (It support Landscape view only)

b) Portrait     ( It support Portrait View only)

c) PortraitOrLandScape  (It support both View )

While Orientation can have following values

a) Landscape

b) Portrait

c) LandscapeLeft

d) LandscapeRight

e) PortraitUp

f) PortraitDown

g) None

To change the page layout we need to set  supportOrientation property to “portraitOrLandscape” And design the page in such a way that it automatically resize according to screen and take their position else you have to do programming for it to put control at proper place.

In current example I have use stack panel and in this stack panel I have used image control. To enable page orientation I have just change the support orientation property.  To know we are seeing which orientation I have added an event which is page orientation event.

You can say it will be simplest example for more information please download the project. (indiandotnet_Wp7_PageOrientation.zip)
