Can DataGridViewComboBoxCell be able to edit by user (like a normal Combobox)?

Hi,
I modified my code as attached, now I can type in the combobox cell and the data was added to the items list, but when I leave the editing cell, the data disappeared from the text display area of the cell (nothing displayed). what's wrong? thanks a lot.

private void dataGridView1_CellValidating(object sender, DataGridViewCellValidatingEventArgs e)
{
if (dataGridView1.CurrentCell.IsInEditMode)
{
if (dataGridView1.CurrentCell.GetType() == typeof(DataGridViewComboBoxCell))
{
if (!((DataGridViewComboBoxColumn)dataGridView1.Columns[e.ColumnIndex]).Items.Contains(e.FormattedValue))
{
((DataGridViewComboBoxColumn)dataGridView1.Columns[e.ColumnIndex]).Items.Add(e.FormattedValue);
}
}
}
}

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

Is your DataGridView databound? What about your combo box column -is it databound? If the combo box column is databound then you need to add the new values to the combo box columns datasource, not the items collection.
