XAML CalculatorBehavior

By Fons Sonnemans, 01-dec-2016

I have been using Adobe software recently and I noticed you could do simple calculations in textboxes. I used it to export Tile Images in different scale sizes. If the 100% scale of an Image is 150 pixels wide you can enter '150 * 1.5'. It will calculate the width of 225 pixels for the 150% scale size. I loved this feature so I tried to implement it also for my own Xaml apps.

The solution is quite simple. I have created a Behavior called CalculatorBehavior. You just use Blend for Visual Studio to drop it on a TextBox control and you are done.

By Fons Sonnemans, 21-mrt-2016

For one of my Windows games I created an AnimatedTextBlock control which animates the Text when it changes. This attracks the user attention. In this blog I will explain how I implemented it. The following animated GIF show's you this AnimtatedTextBlock in my sample app. Everytime you tap the button the text is changed from 'Hello' to 'World' and back.

Op veler verzoek kunt u de slides van deze presentatie hieronder bekijken.

Windows XAML Tips - ResourceDictionary with CodeBehind

By Fons Sonnemans, 17-apr-2015

I have created XAML solutions (WPF, Silverlight, Windows Phone, Windows 8) for about 7 years now. This week I learned a new feature which I thought wasn't possible. I learned how you can place DataTemplates with eventhandlers into ResouceDictionaries. I thought this wasn't possible because ResourceDictionaries don't have CodeBehind files to write the eventhandlers in. But I was wrong. You can add a CodeBehind to a ResourceDictionary but you will have to do it manually. This makes it possible to move more DataTemplates and ControlTemplates from Pages and UserControls to ResourceDictionaries which can help to avoid duplicate XAML code.
