禁止提交，除非所有字段都已填写asp.net和c#（选择题测验）

我正在尝试创建一个选择题测验，用户将回答问题，并在提交时获得分数。如果他们没有回答其中一个问题，我将使用所需的字段验证器显示消息，然而，即使我在点击提交时没有完成所有的问题，系统仍然会计算他们的分数。 我需要能够停止提交，直到所有单选按钮列表完成，但我不知道如何做到这一点。 我的代码在这里：

在未填写答案时点击提交后：


我的submit按钮会像预期的那样消失，但我希望能够阻止它被提交并输出分数，直到所有问题都得到回答

对所有这些都是陌生的，如果这看起来简单或愚蠢，那么很抱歉。
谢谢
我不认为你的代码中有问题，除非所有单选按钮都因为FieldValidator而未被选中，否则它将无法工作，或者你想要其他东西？@MAdeelKhalid，我添加了屏幕截图来说明我的意思
