How can we pass data from one opened form to another?

by

Depends how fancy you want to get.

Simplest approach is just to call methods directly.

Parent 

_child = new ChildForm();

then, when you detect updates (TextChanged, SelectedIndexChanged etc.)

_child.UpdateData(someDataCollectedFromParent)

Child

public void UpdateData(MyObject data)
{
    textBox1.Text = data.FirstName;
    textBox2.Text = data.SecondName;
}

Other than that, you could build your message passing mechanism or look into the DataBinding infrastructure.
