如何在DataGridViewComboBoxColumn中更改单元格的ComboBox样式 [英] How to change cell's ComboBox style in DataGridViewComboBoxColumn

问题描述

DataGridViewComboBoxColumn中的单元格具有ComboBoxStyle DropDownList。这意味着用户只能从下拉列表中选择值。底层控件是ComboBox，所以它可以有样式DropDown。如何更改DataGridViewComboBoxColumn中底层组合框的样式。或者，更一般的是，我可以在DataGridView中列出一个用户可以输入的下拉列吗？
