I was able to implement the selectbox but onchange and OnSelectedIndexChanged are not firing. Any insights?

<div class="hasJS">
<asp:DropDownList class="custom" ID="myid" runat="server" OnSelectedIndexChanged="change" OnTextChanged="change" onChange="myChange();">
<asp:ListItem>Hello</asp:ListItem>
<asp:ListItem>Hello1</asp:ListItem>
<asp:ListItem>Hello3</asp:ListItem>
<asp:ListItem>Hello4</asp:ListItem>
<asp:ListItem>Hello5</asp:ListItem>
<asp:ListItem>Hello6</asp:ListItem>
<asp:ListItem>Hello7</asp:ListItem>
<asp:ListItem>Hello8</asp:ListItem>
</asp:DropDownList>
</div>

 <script type="text/javascript">

   $(function () {

       $("select.custom").each(function () {
           var sb = new SelectBox({
               selectbox: $(this),
               height: 150,
               width: 200
           });
       });

   });

   function myChange() {
       alert("Hai");
   }

    </script>

解决方案

set autopostback=true for DropDownList ;

<asp:DropDownList class="custom" autopostback="true" ID="myid" runat="server" OnSelectedIndexChanged="change" OnTextChanged="change" onChange="myChange();">
