A few days ago Microsoft released the new Windows 10 SDK Preview Build 16225 (Fall Creators Update/CU2). While browsing the 'API Updates and Additions' I noticed there is a new Spacing property for the StackPanel control. You can use it to set the amount of space between each child element. The StackLayout control of Xamarin Forms already had this property. This will make it easier to add this property to the XAML Standard.

Paging, sorting and filtering are common features in websites. Microsoft has written a tutorial how to implement these features in ASP.NET Core MVC with Entity Framework Core. The described solution works but I found it a bit too primitive. It triggered me to create a more powerful solution. Before you can start using my solution you should first read this tutorial, it explains how you can add Entity Framework Core to an ASP.NET Core MVC application.

XAML Animated Headered TextBox Style (Part 2)

Last week I wrote a blog item about the XAML Animated Headered TextBox Style. I got a lot of reactions on Twitter. Pieter Otten challenged me into adjusting my solution to make it conform the Material Design guidelines. In Android the header (Label) of the TextBox (Text Field) animates on Focus not when you enter a value. I tried to implement this by adjusting my style but that didn't work. I had to introduce an extra behavior to get it to work. See the result in this video.

A while ago I saw a beautiful effect in an Android app which I was using. It had textboxes with a placeholder text. This placeholder text moved to the header when you enter the first character in the textbox. This triggered me to do the same in a Windows 10 XAML app (UWP). This is a video of the result.

XAML Storyboard.IsPlaying Attached Property

XAML is very powerful. I have blogged about behaviors a lot. They are great but also have limitations. You can only drag them on Controls, not on Storyboards. To "fix" this I came up with a solution using Attached Properties. The designer support isn't as good with Behaviors but who needs that if we have IntelliSense.

I love C#, XAML and Blend. It is very powerful and lets me create powerful solutions. As a example of it's power I will demonstrate my ScrollSelectedItemIntoViewBehavior. It will let you scroll to a selected item into view of a ListView or GridView without having to write any code.

XAML CalculatorBehavior

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.

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.
