Hello,​

How can I use Trigger and Setter for a Button to change the BackgroundColor based on it's IsEnabled so if IsEnabled is True then the Background is Navy otherwise it's LightGray?

You can add two <Trigger> in <Button.Triggers>, when IsEnabled Property= true, set the background color to Navy. when IsEnabled Property= false, set the background color to LightGray.

   <Button Text="test" IsEnabled="False" >  
               <Button.Triggers>  
                   <Trigger TargetType="Button"  
                    Property="IsEnabled" Value="True">  
                       <Setter Property="BackgroundColor" Value="Navy" />  
                        
                   </Trigger>  
                   <Trigger TargetType="Button"  
                    Property="IsEnabled" Value="False">  
                       <Setter Property="BackgroundColor" Value="LightGray" />  
     
                   </Trigger>  
               </Button.Triggers>  
     
           </Button>  

Here is a official article about the Xamarin.Forms Triggers, you can refer to it.
