AJAX :: Autocomplete / Can't Get It To Hit The Method In My Service With A Signature?
Apr 9, 2010
I have a web control with a text box configured like this:
[Code]....
I am unable to get it to hit the method in my service with a signature like:
public
string[] GetOrganizationNames(string searchText,
int count)
but it does get to the method if I change the signature to:
public
string[] GetOrganizationNames()
For obvious reasons the second one will not do me any good. I have verified the data coming back from the method is good.

I am trying to use the below code to call a wcf service method for Autocomplete functionality in a TextBox. I have written the following query:
$(document).ready(function () {
$("#<%= txtCompany.ClientID %>").autocomplete [URL], {
dataType: 'json',
parse: function (data) {
var items = data.d;
var parsed = [];
for (var i = 0; i < items.length; i++)
parsed[i] = {
data: [items[i]],
value: items[i],
result: [items[i]]
};
return parsed;
}
});
});
The same query works if I pass a Java Script array variable instead of the wcf service method. The wcf service method contract is:
[OperationContract]
[WebInvoke(Method = "GET", BodyStyle = WebMessageBodyStyle.WrappedRequest, ResponseFormat = WebMessageFormat.Json)]
string[] GetTestCompanyList(string prefixText, int count);

i have developed a AutoComplete Search with the JAX AutoCompleteExtender Now i found a solution to use these control without a webservice (amsx) you only have the function in the codebehind (default.aspx.cs) , to do this you must let theServicePath empty. In the codebehind of your webpage is only the function which gets the data from the database.Important the function must be static !!

I'm going on my 3rd day trying to get my Ajax AutoComplete textbox to call my web method. Based on my google searches, I'm not alone. I suspect the problem has something to do with the ServicePath property on the extender, although I'm not sure. My web service is at the same level, on the same server as my test web page. I'm not sure exactly what should go into the ServicePath property, although I think I've tried every possibility. Below is my web service followed by my script.

I have two methods that do the similar thing. There are small differences here and there, which I can control by passing arguments to them when I call them, so I can effectively merge them. However one returns a string, and the other one an ArrayList. On the top of my head, I could merge them and return an Object, and then get the information I need. Is there a way though to return multiple types in the method's signature? What's the proper way to implement this?

I have never write code like this... so I am trying to explian what problem I meet here..
assuming I have 2 web service
one named WS1 another named WS2
WS1 (send data to WS2) → WS2 then WS2 (receive data from WS1 and do something then return result to WS1)→WS1
if I want to add digital signature between WS1 and WS2 so that WS1 connecting to WS2 , WS2 will recognize who is connecting by digital signature
what do I need if I want to do that? and how to do?

I'm helping out a colleague on this one so if I'm missing some details that's why.We have an asp.net 3.5 web application calling a WCF service. Originally the app used a "Web Reference" to register the service however after having some trouble and burning an incident with Microsoft their solution was to replace the "Web Reference" with a "Service Reference" to the WCF service.This is great except the problem is that when we create a Service Reference, the method signatures are different than they were when a Web Reference was used.From what I've read this may be expected, however in our case this would mean some significant changes to the application and of course it was due yesterday...so......I'm wondering two things:Is it normal/expected that method signatures will change based on the reference type?Is there a way to create the Service Reference that will generate method signatures identical to the original Web Reference?

i have a dynamic data layer, i.e every user can add custom fields to database tables, so i need dynamic methods in my application.
i know i can use params to specify a variable number of parameters for a method, but the gridview in asp.net looks for a method with the same fields it is updating, i.e if gridview updates fields :name, age, phone, email(suppose email is a custom field of a certain user i.e it doesn't exit for another), and the object data source calls the update method with signature : (name, age, phone, params object[] custom_attributes) an error is generated that the gridview can not find the method with the signature(name, age, phone, email)

I have a text box and ajax autocomplete control extender in my Master Page that it is not working at all. When I type some characters on the text box it doesn't trigger the autocomplete. I have a web service that contains the function code. I est my code on a single Web Page (No Master Page) and it works perfectly. Also, it works fine if I include the text box and the extender on the Content Page instead of on the Master Page. It is important to keep the text box in the Master Page for me. I am using Visual Studio 2008 and ASP 3.5. MASTER PAGE.

I'm creating just simple autocomplete sample.
taking one textbox adding autocomplete extender as
<asp:ScriptManager ID="ScriptManager2" runat="server">
<Services>
<asp:ServiceReference Path="WebService.asmx" />
</Services>
</asp:ScriptManager>
<asp:TextBox ID="TextBox1" runat="server" EnableTheming="True" ></asp:TextBox>
<cc1:AutoCompleteExtender ID="AutoCompleteExtender1" runat="server" MinimumPrefixLength="1" ServiceMethod="GetCountryInfo" ServicePath="WebService.asmx" TargetControlID="TextBox1">
</cc1:AutoCompleteExtender>
<asp:Button ID="Button1" runat="server" Text="Button" onclick="Button1_Click" />
Also creating web services as "WebService.asmx" & code inside this file is that
<%@ WebService Language="C#" CodeBehind="~/App_Code/WebService.cs" %>
------
then in Webservice.cs file i write code as
public class WebService : System.Web.Services.WebService {
MySql.Data.MySqlClient.MySqlCommand cmd = new MySqlCommand();
MySql.Data.MySqlClient.MySqlConnection con = new MySqlConnection();
//MySqlDataAdapter da = new MySqlDataAdapter();
MySqlDataReader dr;
public WebService () {
//Uncomment the following line if using designed components
//InitializeComponent();
}
[WebMethod]
public string[] GetCountryInfo(string prefixText)
{
int count = 10;
string sql = "Select * from tbl_patientmaster Where P_NAME like '" + @prefixText + "%'";
con.ConnectionString = System.Configuration.ConfigurationManager.AppSettings["HMSDBConnectionString"].ToString();
con.Open();
MySql.Data.MySqlClient.MySqlDataAdapter da = new MySql.Data.MySqlClient.MySqlDataAdapter(sql, con);
da.SelectCommand.Parameters.Add("@prefixText", MySql.Data.MySqlClient.MySqlDbType.VarChar, 50).Value = prefixText + "%";
System.Data.DataTable dt = new System.Data.DataTable();
da.Fill(dt);
string[] items = new string[dt.Rows.Count];
int i = 0;
foreach (System.Data.DataRow dr in dt.Rows)
{
items.SetValue(dr["P_NAME"].ToString(), i);
i++;
}
return items;
}

When trying to edit the word before the delimiter the service method is not even called in IE but works fine in Chrome.
As an example, while '$' is set as a delimiter;
$csAux.Value$csNeedsPO.Valu
Now, editting the word
csNeedsPO => the autocomplete populates as expected succesfully.
csAux.Value => doesnT trigger the method in the background.

I want to create a web method that accepts a List of custom objects (passed in via jQuery/JSON). When I run the website locally everything seems to work. jQuery and ASP.NET and everyone is happy. But when I put it on one of our servers it blows up. jQuery gets a 500 error after the ajax request with the response being:
System.InvalidOperationException: EditCustomObjects Web Service method name is not valid.

I have this version of the autocomplete control working when returning XML from a .ashx handler. The xml looks like this:
<?xml version="1.0" encoding="UTF-8" standalone="no" ?>
<States>
<State>
<Code>CA</Code>
<Name>California</Name>
</State>
<State>
<Code>NC</Code>
<Name>North Carolina</Name>
</State>
<State>
<Code>SC</Code>
<Name>South Carolina</Name>
</State>
The autocomplete code looks like this:
$('.autocompleteTest').autocomplete(
{
source: function(request, response) {
var list = [];
$.ajax({
url: [URL]
dataType: "xml",
async: false,
data: request,
success: function(xmlResponse) {
list = $("State", xmlResponse).map(function() {
return {
value: $("Code", this).text(),
label: $("Name", this).text()
};
}).get();
}
});
response(list);
},
focus: function(event, ui) {
$('.autocompleteTest').val(ui.item.label);
return false;
},
select: function(event, ui) {
$('.autocompleteTest').val(ui.item.label);
$('.autocompleteValue').val(ui.item.value);
return false;
}
});
For various reasons, I'd rather be calling an ASP.NET web service, but I can't get it to work. To change over to the service (I'm doing a local service to keep it simple), the start of the autocomplete code is:
$('.autocompleteTest').autocomplete(
{
source: function(request, response) {
var list = [];
$.ajax({
url: "/Services/GeneralLookup.asmx/StateList",
dataType: "xml",
This code is on a page at the root of the site and the GeneralLookup.asmx is in a subfolder named Services. But a breakpoint in the web service never gets hit, and no autocomplete list is generated. In case it makes a difference, the XML that comes from the asmx is:
<?xml version="1.0" encoding="utf-8" ?>
<string xmlns=[URL]><State> <Code>CA</Code> <Name>California</Name> </State> <State> <Code>NC</Code> <Name>North Carolina</Name> </State> <State> <Code>SC</Code> <Name>South Carolina</Name> </State></string>
Functionally equivalent since I never use the name of the root node in the mapping code. I haven't seen anything in the jQuery docs about calling a .asmx service from this control, but a .ajax call is a .ajax call, right? I've tried various different paths to the .asmx (~/Services/), and I've even moved the service to be in the same path to eliminate these issues. No luck with either.

I have built a WCF Service that is being consumed by a Silverlight app. At first I created one method that was very simple:
public String SfTest()
{
return "SF Test";
}
No poblem. My silverlight app references my service and displays "SF Test" in a textbox. Now I add a method to my wcf service like this:
public List<String> GetTest()
{
List<String> list = new List<string>();
String a = "a";
list.Add(a);
String b = "b";
list.Add(b);
return list;
}
I update the reference to the service in my Silverlight app and the using statement in my xaml cs page throws an error like the service doesn't even exist although it is there. I am assuming the problem has to do with datatypes or serialization or something like that but it is driving me up the wall. Why can't I consume a simple generic list in my Silverlight app through the WCF service.
