How to „cluster“ XF-controls to a user defined control in code?

Hi all

I want to create my own controls with some "clustered" standard-controls for use it on various pages, but don't know, how to do it .
I further need to have access to the events in the own control (e.g. button.clicked(), text.changed, etc.).
I have to do this in code (without xaml).

My Idea:

Example Definition of "control-class":

public class EntryMitLoeschButton : StackLayout 
{
  public EntryMitLoeschButton() // Entry with delete-button
  {
    var sl = new StackLayout { HeightRequest = 50, WidthRequest = 200, Orientation = StackOrientation.Horizontal };
    var MyEntry = new Entry();
    var btLoeschen = new Button();
    btLoeschen.Text = "XX";
    btLoeschen.Clicked += (sender, e) =>
    {
       MyEntry.Text = "";
     };
     sl.Children.Add(MyEntry);
     sl.Children.Add(btLoeschen);
  }
}

On the Page (dont' work):

var objectx = new EntryMitLoeschButton(); // create the "user-object"
PageStack.childred.add(object): // add the user-object to the StackLayout of the page

Eventhandler to Entry MyEntry (in "EntryMitLoeschenButton"):

??xxdont'knowxx??.MyEntry .TextChanged += (sender, e) =>
{// do something};

Questions:
- is that even possible?
- If yes, can somebody drive me in the right direction please?

Thanks a lot for every feedback.
