c# - Xamarin: how do I change the color of a button added in code?

Question

My Xamarin app creates buttons in code. I can change the color of a button I click, as the button is referenced in its Clicked handler's sender argument, but I want to change the color of buttons that I didn't click. The problem is, how do I find the buttons I want to change?

I thought about using FindByName, but Name doesn't appear to be an attribute.

One way I can think of: loop through all of the buttons until I find the one with the StyleId of the desired button. Is there an easier way than that?

Answer 1

when you create a button in code you need to keep a reference to it, like you would with any C# object you want to reference later

Button MyButton = new Button { ... };
MyButton.BackgroundColor = Color.Purple;

if you need to access it from multiple places in your code, you should declare it as a class level variable to that it has scope throughout your class
