Answer 1

Add your client side function name in onchange events of dropdown like below :

<asp:DropDownList ID="DropDownSubject" runat="server" DataTextField="Word"        AutoPostBack="True" OnSelectedIndexChanged="SelectedChange"        onchange="changeCursor()"> </asp:DropDownList> 

Answer 2

In HTML (.aspx)

<asp:DropDownList ID="DropDownSubject" runat="server" DataTextField="Word" AutoPostBack="True"           OnSelectedIndexChanged="SelectedChange" onchange="YourChangeFun(this);"> </asp:DropDownList> 

In javascript

<script type="text/javascript">       function YourChangeFun(ddl)       {          alert(ddl.selectedIndex);       } </script>
