I am successful in using the AutoCompleteExtender control by make use of web serivces as the data source (ServiceMethod) to the extender control. My question is do we have any way in assining a code behind method as data source to this control.
removing the ServicePath url and assiging code behind method to ServiceMethod attribute will resolve the issue.
When I type into the TextBox that the AutoCompleteExtender is associated with, I get no response whatsoever. Here's the code:
TextBox + AutoCompleteExtender (cell is a TableCell object in a TableRow in a etc etc):

Using autocomplete with <ajaxToolkit:AutoCompleteExtender but nothing happens. The textbox has autopostback=falseon debugging autocomplete.vb page nothing happens

We have a custom Ajax checkbox control. In that control we set value (from inside the control) via a web service call (say WSCall1) to the business engine. There is also an event exposed on the OnClick of checkbox for the end user to have their custom code where the end user have their own web service call (say WSCall2). This event that end users will write is handled inside the ajax checkbox control on the "OnSuccess" of the internal web service call (i.e WSCall1) with an expectation that if WSCall1 succeeds, WSCall2 will get executed. This works fine with Firefox and Chrome but not in IE. In IE sometimes WSCall2 gets executed first and then WSCall1 -- actually there is no gurantee which web service gets called first. For WSCall1 we have used " Sys.Net.WebServiceProxy.invoke"
Is there a way we can make sure that WSCall2 gets only executed on the "OnSuccess" of WSCall1? Isn't the OnSuceess supposed to be executed when the WSCall1 thread returns?
it is possible that AutoCompleteExtender can call a service Web of another project of my solution?
View 1 RepliesI 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?

I have defined a web service function for AutoCompleteExtender, but in addition to the two parameters passed "prefixText" and "count" i want to pass another parameter for a label in that function. So, how to define that ?
View 3 RepliesI have created an autoextender & cannot seem to get it to work within my pages. So I'm missing something probably small yet important.
The webservice AutoComplete.asmx, when called by itself, does return data correctly.
The codebehind for AutoComplete.asmx is located in the App_Code folder.
AutoComplete.asmx and the page from which I am calling it are both located in the root folder.

I have a WCF service returning JSON to jQuery ajax calls and presenting the results on an ASPX page. When the page is NOT under SSL, the ajax calls work perfectly. When the page IS under SSL, the calls fail. I understand that this behavior must be due to the Same Origin Policy (SOP).
So, how do I setup my WCF service to accept calls from an SSL-secured page? Does the WCF service also need to be secured? If so, how do I do this?
I have an AutoCompleteExtender control as below. I have tested the web service and it is working. When I debug, there is no error message of any kind. But when I type in the TextBox1, the auto completion does not work. Does somebody know what could be the cause?

i want to use autocompleteextender in User Control.
i tried this but not getting any effect
i used webservice asmx file
I'm using the AutoCompleteExtender control with a textbox. The control functions the way I want it to but I have one issue with it. When the page first loads I type something in the textbox and I get a list of suggestions from my database. When the list is quite big the vertical scroll bar appears on the right side of the browser window and the textbox is repositioned to the center of the page (I want the textbox to be centrally positioned and I'm using <center> tags). Unfortunately the AutoCompleteExtender list doesn't reposition and is misaligned. The same thing happens when the browser window is resized.
I've played around with CSS and OnClientShown and haven't managed to fix this. I'm currently using IE8.
I am developing a user control. This user control is having 2 Dropdown controls and one textbox('txtCustomer'). I am using autocompleteextender for the text box. This 'txtCustomer' control populates the data based on the value selected in 2 dropdowns.
I need to pass the selected value of this 2 dropdown to my meb method. I am not using web service(.asmx page) for this application instead i am using page level web method. I tried to access the controls from the web method inside the Page. but all the identifiers and controls of the page returning null in the web mothod. I have analysed it is because the events "page_Load and page_Init" are not getting fired.
I use AutoCompleteExtender control in an application. When user types an account name to pull a report, the auto complete control lists the top 40 account names from database, user is able to select an account name or type exact account name to pull a report.
It works fine on regular browsers. But the auto complete function does not work on blackberry browser. No error message either. If user types an exact account name, a report can still be pulled. But if a user does not know an exact account name, no data will return because that wrongly typed account name does not exist.
Does somebody know how I can make auto complete work on blackberry or does somebody know any alternative method?
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.
on page AutoCompleteExtender is implemented and just below it, one dropdown is there.
When AutoCompleteExtender displays the list it is getting hide by the below dropdown.
All the controls on page are dynamic.
So, i cannot hide the other dropdowns to get it work.
I have a SOAP web service and I'm trying to figure how to save/log the last 10 requests for each user. Each user is required to send their user/pass in each request, so it's easy to know who the request originated from. With these last 10 requests saved, my goal is to develop some sort of page that will allow them to log-in with their credentials and view the raw request, the actual SOAP message, http header information, and anything relevant that I can think of.
The point is to allow people to troubleshoot their own connection issues instead of having to contact me each time they can't connect, have trouble formatting their request, etc....
My first thought was to store all this information in memory in a hashtable or something, but that may have scalability issues when we have hundreds/thousands of users hitting the web service.
We could use our database to store these requests. Instead of hitting the database each time, I may need to create some "buffer" mechanism that will only update the database after the buffer gets to a certain number of requests. Is there an existing library or mechanism that will do this?
We can't store these requests on the file system on the machine hosting the web service. Since these requests can potentially contain sensitive information, it's a business decision that I'll need to work around. Or maybe there's a better way to achieve what I'm trying to do?
Are web service calls synchronous or asynchronous by default? How is synchronicity determined, by the service or by the client?
I have code similar to the following:
try
{
string result = MakeWebServiceCall_1(); // this is a third party webservice
[code]....
In the above, SetStatus is writing to the same tables that the third party web services read from. If I change the status before both web service calls have completed, it's going to make a big mess and I'm going to get fired. How do I know/ensure that the webservice calls are synchronous?
I've got a web app running with purely web services like these:
Code:
<WebMethod()> _
<ScriptMethod(ResponseFormat:=ResponseFormat.Json, UseHttpGet:=False)> _
Public Function EditService(ByVal toddtype As String _
, ByVal fromddtype As String _
[Code] ....
And I want to log each web service call. I don't want to bother my database with this log - I would prefer to have the web app log to a text file on the web server itself.
How would I open and access a log file like this from a bunch of web services? Does web app still have application startup like events???
I'm trying to make API calls to a service provider. I've never tackled JSON requests before but I want to give it a go - as they seem less verbose than XML. Could someone be kind enough to give me a simple example here?
My confusion stems from some libraries I've come across. Do I need to add any libraries to my project? Or is it just a matter of creating a string that complies with JSON syntax and send it via a WebRequest?
We have a page that makes a request to a 3'rd party web service. When under heavy load this response time extends significantly, however the 3'rd party reports back that there times for processing remains constant. There timings show that from the time they receive a request to the time they send it back is always around 1.5-2.0 seconds. Now we are experiencing wait times of over 20 seconds. My understanding of ASP.NET is that each request will run on a IIS thread pool thread and make the request to the 3'rd party service return and process. So I don't really understand what could be blocking on our end. Is there something I am missing?? Is there a threshold limit beyond IIS that is blocking?
If I am missing something a physical book recommendation that covers this subject would also be a very welcome addition to any answer.
This is quite straight forward. I'm calling a web-service (.asmx, with session enabled) from a c# application. I want each call to be with the same session key as the previous one (as opposed to creating a new session key each time).
Here's my (nothing-out-of-the-ordinary) code:
[Code].....
We have a WCF service (BasicHttpBinding) which will always fail after 30 seconds. Calls under 30 seconds complete without error. Anything over 30 seconds will fail with a 502 Bad Gateway exception:
System.Net.WebException: The remote server returned an error: (502) Bad Gateway.
But yet the WCF call continues to run in the background (and will eventually complete). We have confirmed that the BasicHttpBinding - Binding - sendTimeout (in web.config) is greater than 30 seconds (actually set to 5 minutes). We confirmed this both on the client and the server.
Here is the full stack trace:
System.ServiceModel.ProtocolException: The remote server returned an unexpected response: (502) Bad Gateway. ---> System.Net.WebException: The remote server returned an error: (502) Bad Gateway.
at System.Net.HttpWebRequest.GetResponse()
at System.ServiceModel.Channels.HttpChannelFactory.HttpRequestChannel.HttpChannelRequest.WaitForReply(TimeSpan timeout)
[Code]....
where this 30 second "timeout" is coming from or why a 502 Bad Gateway error is returned?
SOLUTION: We are using the IIS7 Application Request Routing Module which has Proxy settings of its own. The Proxy settings have a default timeout of 30 seconds. Increasing this to 600 seconds (10 minutes) solved our problem. The Bad Gateway error is not completely correct but WCF Trace Viewer (see answer) helped see that the problem was not the service itself but an issue in between the client and the wcf service.
I can't seem to call a web service method from Ajax with both POST and GET.
Initially only the POST would work and GET would causes this error:
{"Message":"An attempt was made to call the method u0027getDatau0027 using a GET request, which is not allowed.","StackTrace":" at System.Web.Script.Services.RestHandler.GetRawParams(WebServiceMethodData methodData, HttpContext context)at System.Web.Script.Services.RestHandler.ExecuteWebServiceCall(HttpContext
context, WebServiceMethodData methodData)","ExceptionType":"System.InvalidOperationException"}
I fixed that by adding this attribute: [ScriptMethod(UseHttpGet=true)] but now GET causes this error:
[code]....
So is it true that you can only use either POST or GET and not both from Ajax?
