<p>Cells in DataGridViewComboBoxColumn have ComboBoxStyle DropDownList. It means the user can only select values from the dropdown. The underlying control is ComboBox, so it can have style DropDown. How do I change the style of the underlying combo box in DataGridViewComboBoxColumn. Or, more general, can I have a column in DataGridView with dropdown where user can type?</p>

```
```
void dataGridView1_EditingControlShowing(object sender, 
    DataGridViewEditingControlShowingEventArgs e)
{
    if (e.Control.GetType() == typeof(DataGridViewComboBoxEditingControl))
    {
        DataGridViewComboBoxEditingControl cbo = 
            e.Control as DataGridViewComboBoxEditingControl;
        cbo.DropDownStyle = ComboBoxStyle.DropDown;
    }
}
```
```
