Trigger element (XAML) is not supported in a UWP project

Question

I\'m developing a Universal Windows application for Windows 10 and one of the first things I found is that the Trigger element (XAML) is not supported when styling images. H

Answer 1

No, you don't have Trigger support in UWP.

A workaround is to use DataTriggerBehavior with a ChangePropertyAction to accomplish the exact same thing.

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


    
        
            
                
            
        
    

Note that you will need to include BehaviorsXamlSDKManaged from C:\Program Files (x86)\Microsoft SDKs\Windows\v8.1\ExtensionSDKs\BehaviorsXamlSDKManaged\12.0\. You will get a warning when you add the reference but just ignore it.

Update: You should be getting an updated Behavior SDK from nuget now.

Then look for the Disabled VisualState and replace it with
