    I am trying to run a web service from a javascript function but am coming across problems.

    It says "'RssService' is undefined" but I cannot see why.
    I know the Namespace is correct and that the service works correctly as I can get it to work in another project easily.

    If I navigate to the webservice/jsdebug and copy the code from this file into the javascript on the page (so to add the proxy code manually) it does one of two things -

    1. If the code from the jsdebug file is inserted into the function calling the webservice it works correctly
    2. if the code is placed otuside of a function I get a "'Type' is undefined'

    Does anyone know why this 'Type is undefined' error is occouring? Why does it not like the Type namespace outside of a function?
    Or does anyone have any other ideas why this may not be working?

    And here is my web service code -

     

    Imports System.Web

    Imports System.Net

    Imports System.Data

    Imports System.Web.Script.Services    <WebService(Namespace:="http://tempuri.org/")> _

    <WebServiceBinding(ConformsTo:=WsiProfiles.BasicProfile1_1)> _

    <    Global.Microsoft.VisualBasic.CompilerServices.DesignerGenerated()> _

    <ScriptService()> _

    Public Class RssService

    Inherits System.Web.Services.WebService

    <WebMethod()> _

    Public Function ReturnRSS(ByVal RSSAddress As String) As String

    Dim ContentString As String = ""

    Dim Ds As New DataSet

    Dim RSSRequest As WebRequest = WebRequest.Create(RSSAddress)

    Dim Pr As New WebProxy("http://192.168.161.1:8080/", True)

    RSSRequest.Proxy = Pr

    RSSRequest.Timeout = 1000 * 10

    Try

    Dim WebResp As WebResponse = RSSRequest.GetResponseDim XmlReader As New System.Xml.XmlTextReader(WebResp.GetResponseStream)

    Ds.ReadXml(XmlReader)

    Dim Alternate As Boolean = True

    ContentString = "<div Class="""" style=""height:150px;overflow-y:auto;""><TABLE><TBODY>"

    For Each Row As DataRow In Ds.Tables("Item").Rows

    If Alternate Then

    ContentString += "<TR Class=""AlternateSearchRow""><TD style=""padding:5px 5px 5px 5px;"">"

    Alternate = False

    Else

    ContentString += "<TR Class=""SearchRow""><TD style=""padding:5px 5px 5px 5px;"">"

    Alternate = True

    End If

    ContentString += "<a href="" mce_href=""" + Row("link") + """><u>" + Row("title") + "</u></a><br><br>"

    ContentString += Row("description") + "<br>"

    ContentString += "</TD></TR>"

    Next

    ContentString += "</TBODY><TABLE></div>"

    Catch ex As Exception

    Throw ex

    End Try

     

    Return ContentString

    End Function

    End Class

     

    Is that all the code needed?

    Hi BobRoss,

    Did you try to place javascript pageLoad function after ScriptManager control?
