AutoCompleteExtender not working

Question

Hi,

following is the code i am using and it is not working.

<asp:TextBox ID="txtWarrantNumber" runat="server"></asp:TextBox>
<AjaxCtrl:AutoCompleteExtender ID="acWarrantNumber" runat="server" TargetControlID="txtWarrantNumber"
    ServiceMethod="GetWarrantNumber" ShowOnlyCurrentWordInCompletionListItem="true"
    CompletionInterval="100" EnableCaching="true" MinimumPrefixLength="1" CompletionSetCount="4">
</AjaxCtrl:AutoCompleteExtender>
        </ContentTemplate>
    </asp:UpdatePanel>
</PopupTemplate>

Public Shared Function GetWarrantNumber(ByVal prefixText As String, ByVal count As Integer) As String()
    Dim warrantNumbers() As String = {"ankit", "sachin", "ankrrr", "ankppp"}
    Return warrantNumbers
End Function

Answer 1

The function GetWarrantNumber needs to be in a WebService as a WebMethod. And you need to provide the location of the WebService.asmx file in the ServicePath property.

AutoCompleteExtender

To do this without a webservice you need wrap your method with the following within the Page:

<script runat="server">
    <System.Web.Services.WebMethod()> _
    <System.Web.Script.Services.ScriptMethod()> _
  Public Shared Function GetWarrantNumber()
  .....
  End Function
</script>

If you do it this way then you don't need to provide a ServicePath.
