To access an instance method or property of one form from another form (or class) in the same application, you need two things:

1. The accessibility of the method or property to access needs to be either public or internal.

2. A reference to the other form's instance.

There are several ways to obtain the second of these requirements, though I'll just give you two here.

If you don't want to disrupt the existing code, then you can obtain a reference to Form2 (say) as follows:

Form2 f2 = (Form2)Application.OpenForms["Form2"];
f2.SomeMethod();

If altering the existing code is not a problem, you can obtain a reference as follows:

// add highlighted code to Form2 class:

class Form2: Form
{
internal static Form2 Instance;

public Form2()
{
InitializeComponent();
Instance = this;
}

// rest of code
}

// now add this code to access SomeMethod() on Form2 from a different form

Form2.Instance.SomeMethod();

hi Gopal,

As per you requirement, I think it would better to create common class which is hold your method and both the place call the same method.
you can also make this method as static.

hope this will help you.
