c# Accessing WinForm control properties from another class

Question

How does one access WinForm controls such as ProgressBar properties from another class?

Please see my code below. I know this might not be the best option

I do not recommend to use this method, for simple reason as mentioned here by one of the comments. But if you really want to access that form control, here is how:

1) Select that control and set its access modifier to internal. 2) Assume your form id is "Form1" and control id is "control1"

Inside your method:

Form1 form = (Form1)Application.OpenForms["Form1"];
// form.control1  should now be available.
