推荐答案

您可以使用JavaScript分别验证每个控件，您需要获取所有文本框和复选框验证它。

见下面的代码片段

You can use JavaScript to validate each control separately, you need to get all textboxes and checkboxes to validate it.
see below snippet

<script language="Javascript">
function validate()
{
   if (!(Checkbox1.checked || Checkbox2.checked || Checkbox3.checked || Checkbox4.checked))
      {
          alert("Please check any of the checkboxes");
          return false;
      }

   if (!(Txt1.Text != "" || Txt2.Text != "" || Txt3.Text != "" || Txt4.Text != ""))
      {
          alert("Please check any of the Textboxes");
          return false;
      }
}
</script>
