Hello,

You can save the button's previous BackgroundTinitList with property. Before you want to reset it. For example, you can save the BackgroundTinitList in the OnCreate method.

   ColorStateList OriginalColorStateList;
    protected override void OnCreate(Bundle? savedInstanceState)
    {
        base.OnCreate(savedInstanceState);
 
        // Set our view from the "main" layout resource
        SetContentView(Resource.Layout.activity_main);
 
        button1= FindViewById<Button>(Resource.Id.button1);
 
        OriginalColorStateList = button1.BackgroundTintList;
...
     }

Then, you want to reset it. You can use button1.BackgroundTintList = OriginalColorStateList;.

By the way, if you still cannot reset it, please share a mini demo with us.
