Databinding Textbox to DataGridview.DataSource, and Programmatically Selecting a Row

Hi,

I have developed a screen where there is a datagridview at the top and a set of tabs at the bottom of the page, which is the details of the selected row in the Datagridview. I set the datasource on the datagridview to my Collection object, and databound each TextBox to a Specific field from the objects.  My collection object inherit from System.Collections.Generic.List<T> 

Emails oEmails = new Emails();

dgEmails.DataSource = oEmails;

tbEmailAddress.DataBindings.Add(new System.Windows.Forms.Binding("Text", oEmails, "EmailAddress", true));

This methodology works when I use the mouse to click around the datagridview, however when I choose to create a new Email:

dgEmails.DataSource = null;
Email oEmail = oEmails.CreateEmail( "Ken", "Ken@Outlook.com");
dgEmails.DataSource = oEmails;

foreach ( DataGridViewRow row in dgEmails.Rows)
            {
                if (row.DataBoundItem == oEmail)
                {
                    row.Selected = true;
                }
                else
                {
                    row.Selected = false;
                }
            }
The correct row is now selected, but the Textbox tbEmailAddress still shows the value from the previous row selected. But if I click on the currently selected row, which is the new row it updates the textbox. How do I update the Textbox value automatically?

Thanks,
Ken
