在单选按钮上点击这个javascript点击
我没试过，但我希望它有用...告诉我结果是什么
你可能知道设置单选按钮的组名属性如果收音机将不起作用按钮位于数据表示控件中，如GridView。这是因为GridView中的单选按钮的行为方式不同。由于GridView呈现为表元素，因此在运行时它将为每个单选按钮分配不同的名称。因此，您可以选择多行。
这是我几年前写的一篇文章，涵盖了您所面临的问题：使用JavaScript验证在GridView中使用单选按钮 [ ^ ]

preform this javascript on radio button click
I didn't Try it but i hope it work...tell me what the result is
As you may know setting the group name attribute of a radio button will not work if the radio button is located within a data representation control like aGridView. This is because the radio button inside aGridViewbehaves differently. Since aGridViewis rendered as a table element, at run time it will assign a different "name" to each radio button. Hence you are able to select multiple rows.
