看看这个：CheckBoxList Selection [ ^ ]

标准对于互联网。当用户看到检查列表时，他们希望能够选择多个内容。当用户看到收音机列表时，他们知道他们只能做出一个选择。您无需做任何事情就可以与用户沟通，他们只知道，无论他们使用什么浏览器，他们所在的国家/地区，他们都了解您的表单。当您执行诸如单选选项清单之类的操作时，它会让用户感到烦恼和困惑，因为他们没有看到他们期望的行为。所以你应该使用一个无线电列表。

Standards are important on the internet. When a user sees a check list they expect to be able to select multiple things. When a user sees a radio list they know they can only make one choice. You don't have to do anything to communicate this to your users, they just know, no matter what browser they use, what country they are in, they all understand your form. When you do things like have single selection checklists it simply annoys and confuses your users as they are not seeing the behaviour they are expecting. So you should use a radio list instead.
