AJAX :: Calling A Web Service From Extender

Apr 8, 2010

VS2008
Using C#
AJAX Toolkit 20229.20185

I have an AJAX auto complete extender that calls a web service to generate a string[] for a textbox. Works great, The issue I am having is that I set the OnClientItemSelected property of the auto complete extender to call a JavaScript function that will intern call another web service to get the remaining data I need based on the item that was selected. (I need this because the auto complete web service only allows for key/value pairs and I need to return 10 columns of data) I cannot get the JS function to call the web service. I keep getting "(Namespace) is undefined" as a JS error. I tried to impliment Microsoft's example located at: [URL] but even if I copy there code line for line in a new project, I still encounter the same error.


Samples.AspNet.WebService.Add(a, b,SucceededCallback); //'Samples' is undefined - runtime If I remove the namespace so that it reads: Add(a, b,SucceededCallback); //Endless loop until you get stack overflow error
Has anyone got MS C# example to work? I saw a lot of people had this line missing in the web service, but I already had it. [System.Web.Script.Services.ScriptService]

WCF / ASMX :: Calling A Web Service Method Asynchronously Does Not Work In Console Application

Sep 15, 2010

I have a web service that has a CreateReport method that generates a report based on the specified criteria.

When I call this method Synchronously using a Windows Application or Console Application, the call works fine and the report is created.

When I call this method ASynchronously (CreateReportASync) using Windows Application the report is created.

When I call this method ASynchronously (CreateReportASync) using Console Application the web service does not even get the call.

I am using VS2005 and .Net Framework 2.0. So the proxy is automatically created with the Async methods. I am not really interested the result of the method call, so I do not add a Callback Delegate.

AJAX :: Creating Simple Autocomplete / Taking One Textbox Adding Autocomplete Extender?

WCF / ASMX :: Calling A Web Service On A Remote Server From A ASPX Page (website Project VS2005)?

Aug 30, 2010

I am maintaining a web site project in VS2005 and have to call a new web service on a remote server. I've done add web reference, and created the .wsdl and .discomap files in the app_webReference folder. When I try to create a object representing the web service in the code ( wsnamespace.serviceName ws = new wsnamespce.serviceName(); ) the code wouldn't compile.

The web site project is already calling other web services. When I right click on the type representing the web service and "go to definition" it takes me to a proxy class (derived from of course SoapHttpClientProtocol) in the metadata. I think this is what's missing for the new web service i'm trying to call. Have I missed any steps?

WCF / ASMX :: "decryption Operation Failed" Exception When Calling Web Service

Dec 20, 2010

These types of exceptions always irritate me because they are almost impossible to reproduce consistently and have almost no documentation other than the cryptic error itself to have any idea on how to fix the problem. So I have a Windows Service that makes a call to a .asmx web service over https on a polled interval every 20 minutes. Once in a great while the following exception message is returned:

Message: The underlying connection was closed: An unexpected error occurred on a receive.

Inner Message: System.IO.IOException: The decryption operation failed, see inner exception. ---> System.ComponentModel.Win32Exception:

The specified data could not be decrypted --- End of inner exception stack trace --- at
System.Net.Security._SslStream.ProcessReadErrorCode(SecurityStatus
errorCode, Byte[] buffer, Int32 offset, Int32 count, AsyncProtocolRequest asyncRequest, Byte[] extraBuffer) at System.Net.Security._SslStream.ProcessFrameBody(Int32 readBytes, Byte[] buffer, Int32 offset, Int32 count, AsyncProtocolRequest asyncRequest) at
System.Net.Security._SslStream.StartFrameBody(Int32 readBytes, Byte[] buffer, Int32 offset, Int32 count, AsyncProtocolRequest asyncRequest) at System.Net.Security._SslStream.StartFrameHeader(Byte[] buffer, Int32 offset, Int32 count, AsyncProtocolRequest asyncRequest)
at System.Net.Security._SslStream.StartReading(Byte[] buffer, Int32 offset, Int32 count, AsyncProtocolRequest asyncRequest) at System.Net.Security._SslStream.ProcessRead(Byte[] buffer, Int32 offset, Int32 count, AsyncProtocolRequest asyncRequest) at System.Net.TlsStream.Read(Byte[]
buffer, Int32 offset, Int32 size) at System.Net.PooledStream.Read(Byte[] buffer, Int32 offset, Int32 size) at System.Net.Connection.SyncRead(HttpWebRequest request, Boolean userRetrievedStream, Boolean probeRead)

So from reading the above message there was an error on receive and the data could not be decrypted. The does not occur consistently, so I don't have a good way of reproducing it. I also lack at low level messaging knowledge and I feel that this is the answer behind this exception; i.e. dropped packets and an incomplete message not appearing to be the same message as sent from the service or something. Any .asmx gurus out there that can give insight and possibly prevention suggestions for the above issue?

AJAX :: AutoComplete Extender Seen Only After One Tab?

Jun 7, 2010

I am using AJAX Control toolkit V-1.0.

I am coming across one problem with auto complete extender in my application, problem seems to simple but i can't find any satisfactory solution. In one form, i have set auto complete extender on one text box, i have set one web service, in which one function is there, which fetches existing records from db, on first load, if i write releavent words with that of db, i can't see the extender, but if once either i minimize the page or give tab despite AutoPostBack property of text box is false, then after writing something in text box shows me the extender.

Here are the properties of both text box and extender

<asp:TextBox
ID="txtCompanyName"
runat="server"
CssClass="txt"
MaxLength="100"
TabIndex="4"
Width="443px"
></asp:TextBox>.........

AutoComplete Extender In Master Page?

Dec 8, 2010

I went through lots of forums, posts etc. But never found really good answer on this.I'm trying to add AutoComplete Extender to TextBox and display some tips to users.Everything is fine when this code is placed in Content Page. But I've got like ~10 Content Pages based on one Master Page so it's completely stupid to repeat the code on each one.

There are some answers on the web but they are only partial ones, check if you wan't:

Could post only one link :/

Here is my code:
