DataTrigger in WinRT?

Question

I was able to find EventTrigger in the WinRT reference, however, I wasn't able to find DataTrigger. I wasn't able to use it in an application either.

Can anyone confirm that DataTrigger is really missing in WinRT? Is EventTrigger the only trigger available in WinRT?

Answer 1

DataTrigger is not currently supported in WinRT XAML.

Addendum by Mike Brown

The DataTrigger API has been replaced with the VisualStateManager a similar API to Data Triggers was provided by the Blend SDK for Silverlight. Since the Attached Behavior Pattern works in WinRT, it is possible to do the same.

Answer 2

What about this project that seems implement triggers in WinRT : http://winrttriggers.codeplex.com/

I don't know when it changed but i have DataTriggerBehavior and GoToStateAction combining them should solve your problem...

xmlns:Core="using:Microsoft.Xaml.Interactions.Core"

ViewSateManager place on root element

<VisualStateManager.VisualStateGroups>
    <VisualStateGroup x:Name="Common">
        <VisualStateGroup.Transitions>
