How can I set a gridviewcolumn to have TextWrap = Wrap when the column is bound at runtime?

I am binding a blank WPF gridview object to columns in a table at runtime using C# Binding and GridViewColumnobjects to manipulate the gridview. I need one type of column to have TextWrapping turned on, and I cannot seem to find the right method. 

System.Windows.Controls.GridViewColumn gvc;
System.Windows.Data.Binding binding;
gView.Columns.Clear();
                foreach (DataColumn column in dt.Columns)
                {
                    gvc = new System.Windows.Controls.GridViewColumn();
                    binding = new System.Windows.Data.Binding();
                    binding.Path = new PropertyPath(column.ColumnName);
                    binding.Mode = BindingMode.OneWay;
                    gvc.Header = column.Caption;
                    switch (column.ColumnName)
                    {
                        case "Unit":
                            gvc.Width = 60;
                            break;
                        case "Message":
                            gvc.Width = 600;
                            break;
                        case "Notes":
                            gvc.Width = 700;
                            //--THIS IS WHERE IS WANT TO SET gvc.TextWrapping="Wrap";

                            break;

                    }
                    gvc.DisplayMemberBinding = binding;
                    gView.Columns.Add(gvc);

}
