Commented:
This is an ASP.NET question rather than a dreamweaver question, but I'll have a go anyway.
Is there any reason why you are using Page_Init to declare the drop down list when it is already hard-coded into the actual page.

Try this approach if you don't need to declare it on server-side:

Imports System
Imports System.Xml
Imports System.Text
Imports System.Net
Imports System.IO
Imports System.String
Imports System.Data
Imports System.Exception
Imports System.Web.UI.WebControls

Class GroupInfo
     Inherits System.Web.UI.Page
     
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs)
      If Not Page.IsPostBack Then
            getListDataFromXML()
      End If
End Sub


Protected Sub getListDataFromXML()
      Try
            Dim docGateway As XmlDocument = New XmlDocument()
            docGateway.Load(Server.MapPath("//Gateway.xml"))
            Dim nodeListGateway As XmlNodeList = docGateway.SelectNodes("//GATEWAYS/GATEWAY")
            Dim nodeGateway As XmlNode
            For Each nodeGateway In nodeListGateway
                  ddlGateway.Items.Add(New ListItem(nodeGateway.SelectSingleNode("NAME").InnerText, nodeGateway.SelectSingleNode("CODE").InnerText))
            Next
      Catch er As XmlException
            Response.Write(er.ToString)
      Catch er As HttpException
            Response.Write(er.ToString)
      Catch er As Exception
            Response.Write(er.ToString)
      End Try
End Sub


End class
