Is there a way to use MAUI Handler without registering with AddHandler?

[qq570850096]

When using MAUI, if MAUI's own controls, such as Entry, do not need to be registered, then in which part of the source code are they registered? Is there a way to use this approach in your own custom controls to avoid registration with AddHandler?

I think this is possible.
As far as I know, you can access the handler of a control at any time.
I.e. you can access the handler of a picker control in codebehind like this:

if (picker.Handler is IDatePickerHandler handler) handler.xxxx

Hope this helps.

Maui's control all use Handler, see

maui/src/Controls/src/Xaml/Hosting/AppHostBuilderExtensions.cs

Line 61 in 3518fc0

handlersCollection.AddHandler<Entry, EntryHandler>();

if you have a custom android AppCompatEditText control, you can inherit EntryHandler

maui/src/Core/src/Handlers/Entry/EntryHandler.Android.cs

Line 14 in 3518fc0

public partial class EntryHandler : ViewHandler<IEntry, AppCompatEditText>

override CreatePlatformView() and use your custom android AppCompatEditText to create it

finally, use .AddHandler<Entry, YourEntryHandler>();
