How about using a public Event

I would do it like this.

public class Form2
{

   private void Submit_Click(object sender, EventArgs e)
   {
       SomethingCompleted?.Invoke(txtData.Text);
       this.Close();
   }
}

and call it from Form1 like this.

private void btnOpenForm2_Click(object sender, EventArgs e)
{
    using (var frm = new Form2())
    {
        frm.SomethingCompleted += text => {
            this.txtData.Text = text;
        };

        frm.ShowDialog();
    }
}

Then, Form1 could get a text from Form2 when Form2 is closed

Thank you.
