推荐答案
在 NullValue属性的作品，但它有一些问题，例如，选择其它值之后。我不'吨删除它...所以我用：
the NullValue works, but it has some problems, for example, after selecting other value, i couldn't erase it...so i used:
private void dataGridView1_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e)
{
if (e.ColumnIndex == 0) // your combo column index
{
e.Value = "Dr.";
}
}
