The new version of Blend for Visual Studio 2013 RC now supports Behaviors. I have used Behaviors for developing Silverlight and Windows Phone applications a lot. Now you can use them for you Windows Store XAML apps too. Two type of Behaviors are supported: Behaviors and Actions. Triggers are "dropped" and can/should now be implemented using Behaviors.
There are 7 build-in Actions: CallMethodAction, ChangePropertyAction, ControlStoryboardAction, GoToStateAction, InvokeCommandAction, NavigateToPageAction and PlaySoundAction. Many were already available in Silverlight. The NavigateToPageAction is new.
There are 3 build-in Behaviors: DataTriggerBehavior, EventTriggerBehavior and IncrementalUpdateBehavior.
You can create your own Actions and Behaviors. Before you can do that you must add a reference to the 'Behaviors SDK'.
While watching the Automated Testing of XAML-Based Windows Store Apps Build session on video I learned something new. There is a new way in Visual Studio 2013 to do data-driven unit testing using the DataRowAttribute. I couldn't find much documentation or samples so I will try to explain it in this blog post.

I have many app is the Windows 8 store now. My Sudoku Free app is the most popular one. It has almost 500.000 downloads and it is played around 13.000 a day. Until recently I received many mails on how to use the app. My support email address is in the Settings panel. Most of these mails where request to add features to the game like 'can I validate a puzzle?', 'can I solve a puzzle?', 'can I get statistics?' or 'can I get a hint?'. Those features are all available in the AppBar of the game. My conclusion is that the average user is still not aware that the AppBar can exist.
To make my users aware of the AppBar I added a peek behavior to it. When you start a sudoku puzzle the AppBar peeks out for just a second, see video. After the implementation I got almost no more of those emails any more.
Before I start I want to make clear that I love Windows 8 and I love to develop for it. But I really have a problem with the implementation of the Search Charm of the Store app. The order in which apps are shown as a result of a search makes no sense. Let me demonstrate this with an example.
De video van mijn 'Black Belt XAML Data Binding' TechDays NL sessie staat online op Channel 9. Vorige week heb ik de presentatie en demo reeds gepubliceerd. Bekijk ook de overige videos van TechDays 2013 the Netherlands of TechDays Belgium.
Op 7 en 8 maart heb ik weer bij het TechDays 2013 event van Microsoft een aantal sessies gepresenteerd. Op veler vezoek publiceer ik hier de presentaties en demo's van mijn sessies. Op Channel 9 zal binnenkort de video van mijn Black Beld XAML DataBinding presentatie getoond worden.
Besides Windows Phone and Windows 8 apps I develop Web sites using ASP.NET. In ASP.NET Web Forms you can define a MasterPage. This technique is called Layout pages in ASP.NET MVC. A simular technique can also be used in your Windows Store apps using XAML. In this blog I will explain how.
Adding a background image to a Windows 8 Store application in XAML can be done in a few different ways. If your app supports navigation between pages you don't want to reload the background image when you navigate to a different page. This doesn't look right on slower ARM devices like the Surface, you will see the image flicker. In this blog I will demonstrate how to set the background image in 3 different ways. The last one without the image flickering.
The new Windows Phone 8 SDK has a new ShareMediaTask class which can be used to share your pictures from code. I wanted to use this class to share a WriteableBitmap. You can use it to share the picture using NFC (Tap+Send), apps or to social media like Twitter or Facebook. In this post I will explain how to implement this.
