Hi Sona

Here you go...

Aspx

<asp:TextBox ID="txtProductCode" runat="server"></asp:TextBox>
                    <cc1:AutoCompleteExtender ID="AutoCompleteExtender1" runat="server" ServicePath="AutoCompleteProductCode.asmx"
                        ServiceMethod="GetProductDescBynumber" MinimumPrefixLength="1" CompletionSetCount="10"
                        EnableCaching="false" TargetControlID="txtProductCode" OnClientItemSelected="PartNoSelected">
                    </cc1:AutoCompleteExtender>

Code behind

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

        If Not IsPostBack Then

            Page.RegisterStartupScript("script1", getScript())
         End If

    End Sub
Private Function getScript() As String

        myStr.Append("<script language=Javascript>")
        myStr.Append("function PartNoSelected( source, eventArgs ) ")
        myStr.Append("{")
        'myStr.Append("var txtProductDesc = window.document.getElementById('<%=txtProductDesc.ClientID %>');")
        myStr.Append("var txtProductDesc = document.getElementById('ctl00_ContentPlaceHolder1_txtProductDesc');")

        myStr.Append("txtProductDesc.value = eventArgs.get_value();")
        myStr.Append("}")
        myStr.Append("</script>")
        Return myStr.ToString
    End Function

Webservce

<WebMethod()> _
    Public Function GetProductDescBynumber(ByVal prefixText As String, ByVal count As Integer) As String()
        Dim obj As New BusinessLayer_Test_DAAB3
        Return obj.GetProductDescBynumber(prefixText, count)'// get your data from xml or DB
    End Function
