AJAX :: Use A AutoCompleteExtender On A MasterPage With PageMethod?
Jun 28, 2010
I put my ScriptManger on the top level Masterpage with EnablePageMethods set to "true".2. I put a AutoCompleteExtender (AjaxToolkit) on a second level Masterpage which derives from the top level MasterPage. The AutoCompleteExtender is used for search with a TextBox. The PageMethod is defined in the Code Behind of this second level Masterpage.3. I have several Contentpages that derive from the second level Masterpage.Problem: The AutoCompleteExtender does not work and that's probably because the PageMethod is defined in the second level MasterPage in the CodeBehind and not in the Contentpage. Ok, so I'm pretty sure what causes the error,- I do not want to use a WebService, because I don't want the search to become public. And as far as I know you can't define a WebService that is only visible to the Website itself - it's always public.- It would be stupid to put the search on every Contentpage just for the PageMethods sake.

My master page code:

<head runat="server">
[code].....
Cs code:
[System.Web.Services.WebMethodAttribute(), System.Web.Script.Services.ScriptMethodAttribute()]
public static string[] SearchCustomers(string prefixText, int count, string contextKey)
{
//return default(string[]);
string[] movies = { "Star Wars", "Star Trek", "Superman", "Memento", "Shrek", "Shrek II" };
return (from m in movies where m.StartsWith(prefixText, StringComparison.CurrentCultureIgnoreCase) select m).Take(count).ToArray();

I have a long running process that i kick off with a pagemethod that normally takes about an hour to complete, when it is finished it returns the result of the method.I then poll with another pagemethod to update the status of the first process.the process is taking 4.5 hours this week which is acceptable and understandable, but the feedback sometimes gives up after a couple of hours and sometimes the main method never returns any feedback to the client.
Regardless of the lack of status updates and final feedback the server still completes the long task.As far as i'm aware we have made no changes to any timeout values.is there a timeout setting that we are hitting that is above 1 hour for ajax methods?

I am using an AJAX.Net to call an ASP.Net PageMethod, which returns JSON serialized JSON data
{"d":"[{"Fromaddress":"testfrom1@test.com","Toaddress":"testto1@test.com"},{"Fromaddress":"testfrom2@test.com","Toaddress":"testto2@test.com"}]"}
The Response Header states the content type as
"Content-Type application/json; charset=utf-8"
However, the data is just available as a string, and does not seem to be available as JSON data from javascript. What do I need to do to work with the returned data as JSON from javascript?

I have a PageMethod that works perfectly well when it either (a) running in the VS dev server, or (b) deployed but marked with UseHttpGet=false.
What doesn't work, and is driving me mad, is having UseHttpGet=true and then deploying it to a test server (Vista & IIS7). It fails to call through the proxy with error code 404 coming back. But it works find if I set UseHttpGet=false.
I have gone through all of the basic stuff I can think to check, and as noted it works perfectly well on the dev box. So there must be something particular about full-blown IIS7 and its config that I am missing..
anything to check in the IIS manager that would cause this to fail? I've tried with forms authentication enabled and disabled, as a few posts mentioned issues with that.

I have a page that requires user login via Forms Authentication. Is it possible to use Page Methods in this page? My current attempt is resulting in the following error:Message: Sys.Net.WebServiceFailedException: The server method 'GetPlanContent' failed with the following error: System.InvalidOperationException-- Authentication failed.

I have written an application that relies upon PageMethods. It was working fine in .NET 3.5 where I would rely upon exceptions to signify something failing during the call. I would then alert the user to what ever it was that happened. All was working great. I transitioned to .NET 4.0 as I am intrigued by the Parallel Computing improvements. Now any exception that I throw in the PageMethod in the code behind is met with an Unhandled Exception. Nothing has changed other than the target framework.

We have used the ajax toolkit auto complete extender in an intranet app which uses Windows authentication. The auto complete uses a static page method in the page code behind to get the results. Even though the page containing the auto complete is authenticated by the server and the asp.net session id set in the cookie, the initial requests from the auto complete result in 401.1 and after few attempts result in a 200. This irritates the users of the app. Also later on there are 401.1 happening intermittently among the various 200 there by affecting the responses.
I have verified these responses by using Microsoft Network Monitor,Fiddler and Firebug. Also these entries are present in IIS logs. I tried to implement the same with a script service but that too gives same issues. Our site has lots of ajax features and controls and everything is working fine, only this issue is there.

need to send a byte array from javascript into a c# page method. The int and string variables work fine, but when I step through the c# code, the "object" which was the byte array is null, even though I checked to see if it had a value in JS.
var byteArrayObj = GetBinaryDataFromFile(filePath);
var tranAttachmentName = filePath.replace(/^.*\/, '');
PageMethods.AddFileToTran(tranId, tranAttachmentName, byteArrayObj, RefreshPage, onTimeout, onError);

i'm using visual web developer 2008 express edition, i added the ajax toolkit to the tools without issue. SOME tools, like the accordian (and others) allow me to drag and drop them onto my forms. but others, such as the autocompleteextender wil not allow me to drag and drop them onto a form. i just get a circle with a line through it (as if to say - this is not allowed) - why is that?
i tried coding the extender in manually like many examples i've seen online:
<cc1:AutoCompleteExtender TargetControlID="txtName" ServiceMethod="GetCustomers" ServicePath="AjaxService.asmx"
MinimumPrefixLength="1" ID="AutoCompleteExtender1" runat="server">
</cc1:AutoCompleteExtender>
but it underlines "cc1" and gives me the error: "unrecognized tag prefix"
what am i doing wrong?

I've got an AutoCompleteExtender on one of my pages, it seems to be working fine aside from this strange behaviour: Let's say I key in 2 characters, the suggestion list would display. When I press on backspace to delete those 2 characters, wait until the suggestion list to disappear, and re-enter those 2 characters, the suggestion list would no longer display (or sometimes would flicker for about a second after losing focus from the textbox) and I'll need to refresh the page just to get it working again.
However, if I do press backspace and delete those 2 characters but not let the suggestion list to disappear and re-enter new characters, it would continue displaying with correct suggestions. This behaviour seems to happen only in IE8, (although it works with IE8 using Compatibility View and Firefox)... My code is almost the same as the sample on this site except for the animations, and the service looks up in a database table.

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.
