           <asp:label id="WelcomeMessage" runat="Server">Welcome to the shop!</asp:label>

           <asp:DropDownList id="LanguageList" runat="Server" OnSelectedIndexChanged="DropList_Changed" AutoPostBack="True"/>

<script runat="server"> 

   Private Languages As New Hashtable()
   
   Public Sub Page_Load()
   
    Languages.Add("English", "Hello, and welcome to the shop")
