Controls on a Form, in Windows Forms, are instantiated as private members of the Form; that is something you should not over-ride by, for example, setting the definition of a Control in the Designer.cs Class to 'Public.

So, you can only "get at" the instances of Controls in the instance of a Form by:

1. Your creating public properties that expose them in their hosting Form:

C#

public Form1()
{
    InitializeComponent();
    TheCheckBox = this.checkBox3;
}

// use this to access 'checkBox3 from "outside" the Form
public TheCheckBox { private set; get; }

2. Your drilling-down into the Controls Collection of the Form instance and getting a reference to them.

C#

CheckBox TheCheckBox = null;

var result = f.Controls.Find("checkBox3", searchAllChildren: true);

// note required cast here if search is successful ...
if (result.Length > 0) TheCheckBox = result[0] as CheckBox;

Use "static" member.
