RequiredField Validation for CheckBox using jQuery in ASP.Net

hi dharmendr

I see your suggested link but see my codes:

<script type="text/javascript">
     function WebForm_OnSubmit() {
        var message = document.getElementById("message");
        message.style.display = "none";
        if (typeof (ValidatorOnSubmit) == "function" && ValidatorOnSubmit() == false) {
              for (var i in Page_Validators) {
              try {
                  if (!Page_Validators[i].isvalid) {
                            message.style.display = "block";
                         }
                      } catch (e) {
                   }
               } return false;
          } return true;
       }
</script>
<div id="message" class="backS2fT1D">
      please fill required field
</div>

here in page I define some textbox  that users should fill them I use validation for all textbox like:

<asp:RequiredFieldValidator Display="Dynamic" ID="RequiredFieldValidator2" runat="server" ControlToValidate="TxtMName"></asp:RequiredFieldValidator>
<asp:RequiredFieldValidator Display="Dynamic" ID="RequiredFieldValidator4" runat="server" ControlToValidate="TxtMobile"></asp:RequiredFieldValidator>
<asp:RequiredFieldValidator Display="Dynamic" ID="RequiredFieldValidator5" runat="server" ControlToValidate="TxtaddC"></asp:RequiredFieldValidator>

so if users doesn't fill one of them below div will display for them:

<div id="message" class="backS2fT1D">
     please fill required field
</div>

now I want define checkbox in this page and if users doesn't select one of checkboxs or doen't fill textboxs it will display above div

how I can do it?

best regards
