Refreshing a DataGridView in one form from another

Question

Hey I have a form which contains a DataGridView which items are bound via a List. From there, I can edit a selected rows items by clicking a button which opens a new form which contains textboxes, combo boxes etc. Once I've finished editing the data, I close the edit form using a button, which takes me back to the main form. Now, once I exit the edit form, the DataGridView is suppose to have its items refreshed so that the updated items are displayed. At the moment, the editing is working fine, however the datagridview is not refreshing. However, if i simply rebind the list in the main form it works, it should work from the edit form but it simply isn't.

Here is a snippet of code from the edit form exit button which is suppose to be doing the refreshing:

                MessageBox.Show("Client successfully edited");

                Client.DisplayClients(Clients.clients, mForm.DataGridViewProp);

                mForm.DataGridViewProp.EndEdit();

                mForm.DataGridViewProp.Refresh();

                mForm.DataPanel.Refresh();

                this.Close();

mForm is an instance of the main form:

     private mainForm mForm = new mainForm();

Clients.clients is a List within a class, and DisplayClients is a method within the client class:

    public static void DisplayClients(List<Client> cList, DataGridView dgv)

    {

        dgv.Rows.Clear();

        foreach (Client c in cList)

        {

            dgv.Rows.Add(c.id_, c.firstName_, c.lastName_, c.homeAddress_, c.workAddress_, 

                c.emailAddress_, c.homePhoneNumber_, c.cellPhoneNumber_);

        }

    }

Any help on the matter is greatly appreciated.
Thanks,
Ari
