title: Trying to call a method from another form
body: <p>I have two forms, the first of which has a datagrid view on it and the second is a data entry form.
  I have created a method that refreshes the datagrid view on the first form but I want to call it when i close form number two. I quickly found that i cant call the method on the first form from the second form so I googled and found that when i open the second form i need to initialise it by using form1(this); however when i do this i get an error message:</p>
  <p>'Form1' does not contain a contructor that takes 1 arguments</p>
  <p>Does anyone know why this isnt working as i copied this from someone elses solution? Also what do i then need to put in my second form to be able to call the method in the first form?</p>
  <pre><code>private void button2_Click(object sender, EventArgs e)
          {
              //Open New Record Form
                        
              Form1 form1 = new Form1(this);
              form1.Show();
          }
  </code></pre>
