Hello ,

You can use the update panel control like below ..

ASP.NET

<asp:scriptmanager id="ScriptManager1" runat="server" xmlns:asp="#unknown">
   </asp:scriptmanager>
   <asp:updatepanel id="UpdatePanel1" runat="server" xmlns:asp="#unknown">
       <contenttemplate>
           <asp:dropdownlist runat="server">
           </asp:dropdownlist>
           <asp:dropdownlist runat="server">
           </asp:dropdownlist>
       </contenttemplate>
   </asp:updatepanel>

and if you want use javascript then use

ASP.NET

<asp:dropdownlist runat="server" autopostback="false" onselectedindexchanged="" xmlns:asp="#unknown">
            </asp:dropdownlist>

Hello ,

If you set AutopostBack as false, the Selected Index changed event for the DDL won't get executed.

Let me know you full prob statement.
