有看一下DataGridViewComboBoxColumn 类 [ ^ ]。级联下拉菜单可以帮助您创建一个选择，您可以选择国家，州和城市。

Have a look at the DataGridViewComboBoxColumn class[^]. Cascading dropdowns might help you create a selection where you can choose country, state and city.

var newColumn = new DataGridViewComboBoxColumn() {
    Name = "abc"
};
newColumn.DataSource = new string[] { "a", "b", "c" }; 
dgv.Columns.Add(newColumn);

但是，现在我想修剪某些行的列表。我正在尝试按行设置每行列表：

However, now I would like to trim the list for certain rows. I''m trying to set the list per row like this:

foreach (DataGridViewRow row in dgv.Rows) {
    var cell = (DataGridViewComboBoxCell)(row.Cells["abc"]);
    cell.DataSource = new string[] { "a", "c" };
}
