Clarify: you do not have checkboxlist, but you do have four checkboxes. Right? And you need to check that at least one checkbox is checked and all textboxes have to be filled?

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

JavaScript

<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>
