Great answer there! The other method would have been:

1. Check if the form you want to update is open.

2. Call the method to refresh your gridVieW.

   **inside your refreshMethod() in form1 make sure you set the datasource to null **

 if (System.Windows.Forms.Application.OpenForms["Form1"]!=null)
            {
                (System.Windows.Forms.Application.OpenForms["Form1"] as Form1).refreshGridView("");
            }
