问题 单项选择题

下述有关选项组叙述正确的是 ______。

A.如果选项组结合到某个字段,实际上是组框架内的复选框、选项按钮或切换按钮结合到该字段上的

B.选项组中的复选框可选可不选

C.使用选项组,只要单击选项组中所需的值,就可以为字段选定数据值

D.以上说法都不对

答案

参考答案:C

解析:[知识点]窗体的基本操作\创建窗体[评析]选项组是由一个组框及一组复选框、选项按钮或切换按钮组成。选项组可以使用户选择某一组确定的值变的十分容易,因为只要单击选项组中所需的值,就可以为字段选定数据值。如果选项组结合到某个字段,则只有组框架本身结合到此字段上,而不是组框架内的复选框、选项按钮或切换按钮。
