Hello, I observed the following problem. I use ASP.NET and jQuery. When clicking on the checkboxes, the div has to change color. But this only works correcty with the input control. When clicking on the .Net-control, the color only changes to blue, so it does not recognize the true state of the control (active, inactive). The problem only(?) appears when using the css-class-property.

<script src="Scripts/jquery-1.4.2.min.js" type="text/javascript"></script>
    
    <script type="text/javascript">

        $(document).ready(function() {
            $(".aspCb").click(function() {
                if (this.checked) {
                    $('.example').css('background', '#ffff00');
                }
                else {
                    $('.example').css('background', '#0000ff');
                }
            });

            $(".cb").click(function() {
                if (this.checked) {
                    $('.example').css('background', '#ffff00');
                }
                else {
                    $('.example').css('background', '#0000ff');
                }
            });            
        });
    
    </script>
    
       
   
    <asp:CheckBox ID="aspCb" CssClass="aspCb" runat="server" />
    <input type="checkbox" id="cb" class="cb" />
    <div class="example" style="width:100px; height:100px">text
    </div>
