You want to OnClick event if you want to call javascript function. 

<asp:CheckBox ID="chkAdd" runat="server" OnClick="return validation();" 
    OnCheckedChanged="btnAddMultiple_Click" AutoPostBack="True" />
<script type="text/javascript">
    function validation() {
        if (confirm("Are you sure you want to post back?")) {
            __doPostBack('<%= chkAdd.ClientID %>', '');
        } else {
            // Optional: change back the CheckBox to original position
            return false;
        }
    }
</script>
