Hello!

I am working with Windows Forms. I have a DataGridView with several DataGridViewTextBoxColumns. When I enter a cell in the DataGridView, ComboBox is displayed in top of that cell - I am using ComboBox instead of DataGridViewComboBoxColumn, because DataGridViewComboBoxColumn becomes very slow when filled with more than 1000 items (I have several thousand).

The problem is: when my ComboBox receives focus, I can't take focus from it with only keyboard. For example: I am typing somethning in the ComboBox. Now I want to jump on the next DataGridViewCell with the keyboard pressing arrow key (and perhaps, pressing Esc key before) - nothing happnes. ComboBox doesn't loose focus, it's not responding either to Esc key, nor arrow keys. I have to use mouse to move to the next cell.

Any idea?

Actually DataGridViewComboBoxColumn is derived from DataGridViewColumn, on the other hand combobox is not derived from that. That's why it is behaving not in the way you expect.
