.NET MAUI › Controls & Views

How do you customize a control's native appearance without a full custom control?

Answer

Use handler mappers to reach into the platform view. AppendToMapping runs after the default mapping so you can tweak native properties per platform, guarded by #if. This avoids subclassing and keeps customization centralized in MauiProgram or a startup routine.

EntryHandler.Mapper.AppendToMapping("NoUnderline", (handler, view) =>
{
#if ANDROID
    handler.PlatformView.BackgroundTintList =
        Android.Content.Res.ColorStateList.ValueOf(
            Android.Graphics.Color.Transparent);
#endif
});

Real-world example A design team removes the Android Entry underline app-wide with one mapper customization instead of a custom renderer.
