События DataGridView

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:

 

0202: PreviewKeyDown

0203: CellBeginEdit

0205: ControlAdded

Вместо «Key0» в текстовом редакторе отобразилась буква «d». Нажимаю «Enter». DataGridView посылает следующие события:
