注解

此属性返回的值Items的属性DataGridViewComboBoxCell返回的CellTemplate属性。This property returns the value of the Items property of the DataGridViewComboBoxCell returned by the CellTemplate property.

ItemsDataSource属性用于填充组合框的选择。The Items or DataSource properties are used to populate the selections of the combo boxes.

如果将字符串添加到Items,则ValueMemberDisplayMember属性无需设置,因为每个字符串添加将用于值和显示。If strings are added to Items, then the ValueMember and DisplayMember properties do not need to be set because each string added will be used for both value and display.

备注

DataGridViewComboBoxColumn 不支持使用具有相同的显示值的多个项。DataGridViewComboBoxColumn does not support the use of multiple items with identical display values.

如果DataSource设置属性,则Items不能使用。If the DataSource property is set, then Items cannot be used.
