Update:

Your Main window

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
        textBox1.Text = "original text";
    }


    private void button1_Click(object sender, EventArgs e)
    {
        new Form2().ShowDialog();
    }
}

Your dialog-form, that will change the values in Form1

public Form2()
{
    InitializeComponent();
    // Get the text from Form1
    textBoxOrg.Text = Application.OpenForms["Form1"].Controls["textBox1"].Text;
}

private void button1_Click(object sender, EventArgs e)
{
    // Change the text on Form1
    Application.OpenForms["Form1"].Controls["textBox1"].Text = textBox1.Text;
}

You probably wan't to change value on public properties instead of UI-elements.

Another, and cleaner way, is to pass fields to the form with a ref
