Customizing a platform view with an existing control handler

.NET MAUI is built on multiple layers, with the top .NET layer abstracting the platform implementations for each platform. However, native platform controls have unique APIs that can’t always be simplified into a single cross-platform API. As a result, MAUI controls may not expose all the APIs available in their native counterparts. This is why we sometimes may need to interact with platform controls through .NET MAUI handlers.

Handlers

A control handler in .NET MAUI is an object that connects a cross-platform UI control with its native platform-specific counterpart. It serves as a bridge between the shared properties defined in .NET MAUI controls and the native platform elements.

UI components in .NET MAUI already come with handlers, allowing us to access and customize the native controls used under the hood. In this recipe, we’ll utilize an existing handler of the Entry element to customize its selection...
