In this code, you pass a text to Form2. Form2 shows that text in textBox1. User types new text into textBox1 and presses the submit button. Form1 grabs that text and shows it in a textbox on Form1.

public class Form2 : Form
{
    private string oldText;

    public Form2(string newText):this()
    {
        oldText = newText;
        btnSubmit.DialogResult = DialogResult.OK;
    }

    private void Form2_Load(object sender, EventArgs e)
    {
        textBox1.Text = oldText;
    }

    public string getText()
    {
        return textBox1.Text;
    }

    private void textBox1_KeyUp(object sender, KeyEventArgs e)
    {
        if (e.KeyCode == Keys.Enter)
        {
            DialogResult = System.Windows.Forms.DialogResult.OK;
        }
    }
}

And this is Form1 code:

public class Form1:Form
{
    using (Form2 dialogForm = new Form2("old text to show in Form2"))
    {
        DialogResult dr = dialogForm.ShowDialog(this);
        if (dr == DialogResult.OK)
        {
            tbSubmittedText = dialogForm.getText();
        }
        dialogForm.Close();
    }
}
