Решил посмотреть на последовательность событий, которые создает DataGridView. В гриде всего один столбец и две строки с текстом.
DataTable table = new DataTable();
table.Columns.Add("key", typeof(string));
for (int i=0; i < 2; i++)
table.Rows.Add("key" + i);
DataGridView grid = new DataGridView();
grid.Dock = DockStyle.Fill;
grid.Parent = this;
grid.DataSource = table;
grid.AllowUserToAddRows = false;
grid.SelectionMode = DataGridViewSelectionMode.FullRowSelect;
grid.AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.Fill;
С помощью UniversalEventHandler сгенерировал код, который ко всем найденным 187-и событиям подключил общий для всех обработчик. Запустил программу и получил от DataGridView следующие события:

На этом события прекратились. Строка «Key0» выделена. Жму на клавиатуре, например, на «d». В результате DataGridView посылает следующие события:
