I am getting error when calling webservice using JSON. my code is as below
[Code]....
after calling the
jquery-1.3.2.min.js code it throws error on this line [Code]....the error is coming on "R"
Yesterday I upgraded to MVC 2 RC. I have several jquery ajax requests that worked fine prior to the upgrade. Sometimes they work, sometimes they don't.
I know the MVC team made changes to the framework to protect against Json Hijacking so that GET requests are not allowed (by default) and I have changed my jquery ajax code to use 'type: "POST",' and then adorned the Action Method with the POST verb.
Again, the odd thing about this is that it works sometimes and other times it doesn't. When it fails, there are no error details. The error code is 12030 or 12031.
I have big problem with the CascadingDropDown. I have 60 CDD with one "Child". So on the page are 60 Parents and 60 Childs. When i use FF3.5 everything works fine when he is the only Browser which is connected to IIS
When i use FF3.0 i get Methode ERROR 403 and 500
When i use IE6 i get Methode ERROR 12030 or 403 or 500
When i use Google Chrome no ERROR no content in the List!?
When i use IE8 sometime it works sometime not!?
This errors are not shown on every DropDownList (but on most of them!) I played with the "<jsonSerialization maxJsonLength="50000000" />" in the Web.config which seams to make it work a little bit better.
What can i do to get the CDD working?
I think it is a timing problem. The CDD are not filled in the order i placed them on the page. Local it works better then remote.
Can you help me?
This is my WebService:
[Code]...
I'm developing an ASP.Net web site using VS 2008 and .Net Framework 3.5, and I want to use jquery ajax in a test page, the code looks like this:
C# Method
[WebMethod]
public static string test()
{
return "Server Response" ;
}
$(document).ready(function() {
$("#myDiv").click(function() {
$.ajax({
type: "POST",
url: "AjaxTest.aspx/test",
data: "",
contentType: "application/json;charset=utf-8",
dataType: "json",
success: function(msg) {
// Replace the div's content with the page
// method's return.
alert(msg.d);
},
error: function(result){
alert("error occured. Status:" + result.status
+ ' --Status Text:' + result.statusText
+ " --Error Result:" + result);
}
});
});
});
So When I use Jquery 1.4.4 like this : I get : Status 200; Status Text: OK When I use Jquery 1.5 I get: Status 200; Status Text: Parsererror So I created a new WebSite in Visual Studio, copy and pased the code there, and it works fine !!!! I can't figure out what causes the problem. Also I have used methods with parameter, and setting data:"{}", and removing data completely, but nothing seems to work. I don't know if has to do anything with the DevExpress components that I'm using or not. I also found a good answer which was working with complete method like this :
complete: function(xhr, status) {
if (status === 'error' || !xhr.responseText) {
alert("Error");
}
else {
var data = xhr.responseText;
alert(data);
//...
}
}
But I don't know if it will work fine or there might be some other problem with this method too. I also don't know how to access response data from here.
I have an ASP.NET form with several update panels. All works great.I use a timer and have it handle some periodic upates. That works correctly too. However, I appear to get an error when I leave the page open running in the debugger. Specifically the above JScript error 12030.I'm not clear how to find the source but I assume it is because my page has logged out. If I refresh I go back to my login page.So, does this sound like the cause? If so, how to I address this?
View 2 RepliesI have a serious problem with "Error on Page". The error message points to line number 939, char 13. In my code behind (C#) in line number 939 is only an obsolete method found which is no longer called. The aspx file has only 339 lines. What the heck is line number 939?The Webapplication allows a special user group to change some group memberships for members of another user group in Active Directory. The App handles 3internal DataViews derived from corresponding DataTables as DataSource for 3 GridViews and some other internal lists with objects (List<obj>).
It uses windows authentication to get current users credentials and his membership in the "Operators" group. This credentials will be passed-through to allow the process managing group memberships in active directory.After starting the App in browser it seems to work fine. But after an indeterminated time it doesn't longer respond. After each click on buttons (or link buttons) you only can see the message "Error on Page" in the browsers status bar below.I played with session timeout, storing the DataTables in session variables, without success.
Last week I found this article here: [URL]" and I addedEnableEventValidation="false" ViewStateEncryptionMode="Never"
to Page declaration. However, at some point the the server does not respond. Each time the worker process on webserver recycles it seems the application turn to wrong state. Might be important: All controls including GridViews are embedded in an AJAX UpdatePanel. How to get a better error message? Debugging is enabled and Custom Error handling On, Off or Remote Only brings the same result as described.
Unknown web method xxx. Parameter name: methodName
[Code]....
I'm trying to implement a view tracking web service on my website. I'm using JavaScript because I want to exclude any search bots from my tracked views. The problem is I'm getting a "Unknown web method" error when I try to use jQuery to post to the web service I've created.
$(document).ready(function() {
$.ajax({
type: "POST", [code]...
The error is an ASP .NET error: Unknown web method TrackItemView. Parameter name: methodName.I've done this hundreds of times (seemingly), but I just can't see what I'm missing. I'm sure it's something small...
I'm getting this error when I'm trying to run a page that works on other servers. Having trouble finding much info on this error or possible solutions.As far as I can tell, the appicable permissions have all been set, on both the app folders and the framework folders. I've taken all the code out of the page to isolate

View 1 RepliesI'm using DataContract/DataMembers to serialise my class to JSON for a webservice, and it all works fine, except for one of my members, which could either be class a, or class b, where class b extends class a.
If I omit the KnownType parameter, then an exception is thrown during serialisation:
Type 'ClassB' with data contract name 'ClassB:http://schemas.datacontract.org/2004/07/MyApp.App_Code' is not expected.
As expected, because the ClassB is an extension of Class A, and so not know to the deserialiser. So I need to add a known type attribute, which I do, to the parent Class which contains the member
[KnownType(typeof(ClassB))]
[DataContract]
This compiles fine, but the page which I am currently testing this on seems to go bizzare, it loads fine, however apparently the Service doesn't exist anymore, as my JS call tells me and throws and error. But I have no idea why adding the known type attribute on my class causes the webservice to apparently not exist :s
Is it something to do with the fact that my setup is ClassA, ClassB: ClassA, and all the examples I have seen, seem show a ClassA: ParentClass, ClassB: ParentClass setup.

I have a project using Crystal Reports 2008, whenever I try to print the report, using the print button on the menu I get an error on one of my machines, the Crystal Print Dialog opens, completely empty and then I get a error from windows:
Windows has blocked this software because it can't verify the publisher.
Name: PrintControl.cab
Publisher: Unknown Publisher
This is only happening on my Windows 7 machine. The solution on my Windows XP machine works fine, even if I hit the site under XP from my 7 machine, so I'm assuming something didn't install properly on 7. Any ideas? The 7 machine print dialog comes up blank, just says Print on the title and then the error comes up. The XP machine Print dialog says Print in the title and says Crystal Reports Print Control before the print options come up.
I don't know what is going on. When I try to add a tab container in my page, it allows me to do that but when I modify the code, the unknown server tag error pops up in the design view of the page.
I checked the source code to see if I had my @register clause in there, and it was there, but still the error shows. I don't know what happened, the last time it worked perfectly.
I have also recently downloaded the cute editor for .net and installed the .dlls to my bin folder and it is showing the same simtoms as well.
I just installed Ajax Toolkit. The controls are available in my Toolbox, but when I insert them in a page, Visual Studio underlines them with the error message "unknown server tag".
I googled the problem and found several ideas :
check if the DLL is in Bin folder check if ajaxToolKit tags prefix is registered in web.config and make sure I'm not using a different prefix in my pages check if the DLL is registered in the pages with <% @ Register ... %>
Unfortunately all of this is fine, but I still can't get the controls to work. Is something else missing ?
EDIT : My environment is ASP.Net 2.0, Ajax Extensions 1.0, Ajax Toolkit 1.0.20229, Visual Studio 2005

I am executing a SSRS 2008 report from report manager so it opens in a web browser. Since it is a big report it takes some time for execution. During this time i get an error icon on the left bottom of the web browser and the execution stops. When I click open the error icon to see the details it says,
"Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 12029."
The other relatively smaller reports are coming up successfully without any issue.
I am using SQL Server 2008 R2 64 bit ent. edition and the OS is Win Server 2003 64 bit SP 2.
Am getting this error on clicking any of my page link.
Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 0"
How do i avoid this error.
I'm working on a vb.net windows project using crystal reports for report generating.I'm using stored procedures as well.Stored procedures are used by crystal reports.When I run report with some parameters it gives error,like this " Unknown Query Engine Error ".I have checked the Stored Procedure and there is no problem with the SP, no extra parameters.

I try to use the jquery + json to get all elements in form and build a JSON var to post in a ASP.NET MVC method.
[Code]....
It method get all fields in a form and build a JSON, but it dont put JSON inside JSON.
Example:
If i have the follow form:
<input name="person.name"><input name="person.age"><input name="person.address.street">
The serialized string build a JSON like this
{ "person.name": "??", "person.age": "??", "person.address.street": "??" }
I need a plugin or some function to generate like this:
{ "person": { "name" : "??", "age" : "??", "address":{ "street": "??" } } }
In my application i use iframe (to be more specific; Greybox tool). Sometimes i had an unkown error when i open page in iframe. Then i applied this fix : [URL] and that unknown error disseppeared. But i have another problem now:( I am using following script to focus to the first textbox whenever my input pages are opened in iframe.
aField = document.getElementById('txt_PID');setTimeout("aField.focus()", 50);
After i applied previous fix, i get this error when i load page in iframe for the first time :
Can't move focus to the control because it is invisible, not enabled, or of type that does not accept focus.
Here, txt_PID doesnt contain any ajaxtoolkit things. (also Enabled= true and Visible=true etc.) . Last thing, my current test page contains just 3 controls: txt_PID just plain Asp.TextBox ajaxHTMLEditor another textboxt with MaskedEditExtender. If i remove HTMLEditor from page; i dont get that error( Can't move focus...) and also i dont get first error which i applied that fix in toolkit.
