推荐答案

创建一列组合框时，必须为这些组合指定一个项目列表，这些列表将在您选择时显示.进入dgv单元格的值必须在该项目列表中.在您的情况下，一个或多个组合框单元格包含一个不在项目列表中的值，因此该单元格值无效.

When you create a column of combo boxes, those combos must be assigned a list of items which will be displayed when you select it. The value which goes into the dgv cell must be in that list of items. In your case, one or more of the combo box cells contains a value which is not in the item list, hence the cell value is invalid.
