AJAX :: AutoCompleteExtender Not Working With WebService?
Feb 24, 2011
I have a textbox with the autocompleteextender in VS2010 that is referencing a webservice. However, nothing I seem to do makes this work as no values are returned when I begin typing in the textbox. When I view the webservice in my browser and invoke it, it returns values so I know that my webservice works. Code below.
I have a web service file in my project having a web method which is used for AutoCompleteExtender and which works fine when I debug it from VS. But when I publish and host it on IIS, it's not working properly. However, I tested the webservice method directly by typing the URL and it gave the desired output. Is their a special setting needs to be done in IIS to make it working or any property of AutoCompleteExtender need to be set?
I am using AjaxAutoCompleteExtender in my asp.net program (C#) . I am applying the extender to a texbox and using internal Web Service. I am getting the desired result, when i am running from the development environment. After Publishing the site to IIS, I am not getting the list and not showing any errors. I have turned off custom errors. My website is not an Ajax Enabled WebSite. So i added the lines into my Web.Config.I tried all service path.. http://localhost/Test/ WebService.asmxhttp://192.109.1.8/Test/WebService.asmxand i tried ~/Test/WebService.aspxWhile testing from the development environment, i am using the last one.I am not sure whether this is the problem with the service path or any permission issue.
I tested the web service.it is working fine.The problem that i want to solve is to make call to webservice. Here is the .aspx code
<asp:TextBox ID="txtFullName" runat="server"></asp:TextBox> <ajaxToolkit:AutoCompleteExtender ID="AutoCompleteExtender1" runat="server" TargetControlID="txtFullName" ServiceMethod="FindFullName" ServicePath="../WebService.asmx" EnableCaching="true"></ajaxToolkit:AutoCompleteExtender> Webservice code : using System; using System.Web; using System.Collections; using System.Web.Services; using System.Web.Services.Protocols; using System.Configuration; using System.Data.SqlClient; using System.Data; using System.Collections; using System.Collections.Generic; /// <summary> /// Summary description for WebService /// </summary> [WebService(Namespace = "[URL]/")] [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] [System.Web.Script.Services.ScriptService] public class WebService : System.Web.Services.WebService { public WebService () { //Uncomment the following line if using designed components //InitializeComponent(); } [WebMethod] public string HelloWorld() { return "Hello World"; } [WebMethod] public string[] FindFullName(string prefixText) { string sql = "Select FName from Investigators Where FName like @prefixText"; SqlDataAdapter da = new SqlDataAdapter(sql,"Data Source=vvvvv;Initial Catalog=vyyyd;Persist Security Info=True;User ID=PowetttrUsyyer;Password=888888); da.SelectCommand.Parameters.Add("@prefixText", SqlDbType.VarChar, 50).Value = prefixText+ "%"; DataTable dt = new DataTable(); da.Fill(dt); List<string> liste = new List<string>(); foreach (DataRow dr in dt.Rows) { liste.Add(dr.ItemArray[0].ToString()); } return liste.ToArray(); } }
I got the auto complete extender working with the database, but will show the autocomplete only if the data is less than around 500 records.... anything above that, and the exntender will not show at all.... Does the auto complete extnder have a limit on the number of records?.
i have an asp.net application in which i have used autocomplete extender now when i deploy it on the server (2003 and iis 6) the autocomplete extender does not work .. i looked on the net and found out the system.web.extensions system.web.extensions.design dll are needed for it, it was not present so i added them to the gac still it is not working i have .net3.5 sp1 instaled on the server.
I tried your code for Autocomplete without Webservice and didn't work on my page. When I tried it on a new project it works fine but on my project it does not. I have other controls on the page but that shouldn't stop it from working right?
In the upper code... AutCompleteExtender1 works perfectly... AutoCompleteExtender2 not working at all. Same web service, same method... both are inside the same .aspx file... both have exactly the same conditions.What is it that I am missing? And if you think that it is because they both calling the same service and method it is not... the second doesn't work with different service or different method (both inside the same service and in the different .asmx file).Can it be, that you simply can't have 2 ACE controls on the same page?And btw, is it possible to run server code once someone selects something from ACE control?
Autocompleteextender not working inside an user control tried all ways. i have a custom function.. inside the cs file itself like the following :-
[Code]....
I did something like this and it worked properly when it was in aspx but when i changed all this to ascx and when i added the user control in aspx the autocomplete is not working. say enablecontext = false; i have even tried that.. its not even reaching till that function. moreover i need contextkey to validate different autocomplete controls inside my page.
I have one web application which is accessible via to different IP addresses (one of them is virtual) now the application is running smoothly when accessed via the original ip address but when the same application(website) is accessed via the virtual ip address the autocomplete extender is not working it is flashing a javascript error 'Stop running the script? A script on this page is causing internet explorer to run slowly
I have added autocompleteextender in page . It was working without parameters , when i have added parameters "pretext","count" it stops working. below are my code :
<div> <asp:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server"> <Services> <asp:ServiceReference Path="~/Admin/WebService1.asmx" /> </Services> </asp:ToolkitScriptManager> <asp:TextBox ID="TextboxCompletelist" runat="server"></asp:TextBox> <asp:AutoCompleteExtender ID="TextboxCompletelist_AutoCompleteExtender" runat="server" ServiceMethod="GetCompletionList" Enabled="True" ServicePath="~/Admin/WebService1.asmx" TargetControlID="TextboxCompletelist" CompletionSetCount="10"> </asp:AutoCompleteExtender> </div> namespace AgentService [WebService(Namespace = [URL] [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] [ToolboxItem(false)] [System.Web.Script.Services.ScriptService] public class WebService1 : System.Web.Services.WebService { [WebMethod] public static string[] GetCompletionList(string PrefixText, int count) { string countryname; SqlParameter[] parm = new SqlParameter[1]; parm[0] = new SqlParameter("@PrefixText", PrefixText); DataTable dt = SqlHelper.ExecuteDataset(AppSetting.ActivateConnection, CommandType.StoredProcedure, "FetchAutoCompleteStates",parm).Tables[0]; List<string> items = new List<string>(); for (int i = 0; i <= dt.Rows.Count-1; i++) { countryname = dt.Rows[i]["statename"].ToString(); items.Add(countryname); } return items.ToArray(); }
I have a webservice "DataService.asmx" which I am using for AJAX calls for insert, update, delete and some other tasks. All the pages are calling webservice smoothly but this new page I added and calling my webservice using the same ajax method not working. Strange thing is that neither its going on SUCCESS nor FAILURE...and put a breakpoint on my webservice but its not going into the webservice...plz help as its been 6 hours now figuring what the problem is..here is the code.
Configuration : Windows Vista,VS 2005,Ajax v1.0.61025 My Html Page

But i am getting Sim is not defined. Error. post ur comments. I have reviewed most of the forums. I am not able to clear
i have tried autocompleteextender using page method and without master page and its working. but now im try to put them into master and its not working. this is my code***********pagename.ascx
I ultimately need to show countries in one drop down then states/provinces drop down of the previously selected drop down. I'm sure everyone has seen this many times. My page shows the countries but does not show values in the province/states drop down. It's as if the webservice is never run. I've tried removing and adding the ajaxtoolkit reference. The tableadaters run simple working sql code. I'm really at a lose here.
default.aspx: ... <%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="ajaxToolkit" %> ... <body> <form id="form1" runat="server"> <asp:ScriptManager ID="ScriptManager1" runat="server" /> <%--Dropdown to display countries--%> Country:<asp:DropDownList ID="ddlCountries" runat="server" DataSourceID="ods_Countries" DataTextField="country" DataValueField="abbreviation"> </asp:DropDownList> <%--data source for the country drop down list--%> <asp:ObjectDataSource ID="ods_Countries" runat="server" OldValuesParameterFormatString="original_{0}" SelectMethod="GetAllCountries" TypeName="countryDataSetTableAdapters.CountriesTableAdapter"> </asp:ObjectDataSource>....................................
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
The web service works - the code is copied practically verbatim from the AJAX Control Toolkit samples. This is really frustrating me. I have looked at other questions on here and not found a solution yet.
I don't get any errors or exceptions. Typing in the text box doesn't do anything, the web service doesn't hit the break point.
I have ajax autocompleteextender and it is working fine with our test enviornment where we dont have secured HTTP. But while moving the code to Qa, which runs on HTTPS, AutoCompleteExtender stops working. I debugged and see control is going to webservice but unable to fetch data or call database from webservice.
I am trying to setup a Spring.net web-service but keep getting an error message that I cannot figure out.
Error: System.NotSupportedException: Target 'target' of type 'Spring.Objects.Factory.Support.RootWebObjectDefinition' does not support methods of 'StudentRegistration.Services.IBoundaryService'. at Spring.Util.AssertUtils.Understands(Object target, String targetName, Type requiredType) at HelloWorldExporter.GetAllBounds()
Code: public interface IBoundaryService { XmlDocument GetAllBounds(); } public class BoundaryService :IBoundaryService { public virtual IBoundaryDao BoundaryDao { get; set; } public virtual XmlDocument GetAllBounds() { XmlDocument xmlDoc = new XmlDocument(); xmlDoc.LoadXml("<test>ok</test>"); return xmlDoc; } }
i have declared an int variable; something like that:
int ret = ws.GetVersion();
the webservice correctly load the value and return to the client, however in the client if i select ret and hit shift+f9 it say that ret doesnt exist in that context.but if that would be the case i would get a compiler error,
