Everything is working as expected. Therefore, I am closing this case as not reproducible.
Testing Note
Do not use appearance to determine if a button is disabled or not when you have explicitly set a BackgroundColor. You will want to click the button to see if the button is operational.
Important - Understanding Scope
This is extremely important to understand... The RadButton is built on top of the .NET MAUI Button control. This means if you are having an issue, please first test your perceived behavior with the MAUI Button component before opening an Issue on our Forums.
That way you know where the problem originates from.
Test 1<telerik:RadButtonAutomationId="button"Text="Back"HorizontalOptions="End"VerticalOptions="Center"Command="{Binding BackCommand}"BackgroundColor="{DynamicResource PrimaryColor}"Margin="15"IsEnabled="True"/>Test 2<ButtonAutomationId="button"Text="Back"HorizontalOptions="End"VerticalOptions="Center"Command="{Binding BackCommand}"BackgroundColor="{DynamicResource PrimaryColor}"Margin="15"IsEnabled="True"/>Result: Same Behavior is Observed on Both Tests - Everything is working as Expected
If the problem is only happening with RadButton, you can open an Issue in the Telerik forums.
If the problem also presents itself with Button, then you will want to look at MAUI's Issues and see if someone else has already reported it. If noone else has reported it yet, the prepare a full reproducible implementation and open a new Issue (do not link back to a 3rd party forum).
