I currently facing a cascading drop down list problem. When I develop my website at local pc, everything work just fine. However I deploy it to server, I get Method Error 500.
View 4 RepliesRegarding this example: [URL] .... it works locally, within VS 2012.
But when I publish to a local or remote webserver, it doesn't show an error, but the dropdown lists are populated with this line: [Method Error: 500].
I have the method 500 error problem, I have tried to do a simple reproduction of the problem still the same, if I run the webservice [URL] it returns the values needed ok (5) in xml format, but the dropdown always return error 500 inside, here are the codes (Using VS2008, NF3.5, Windows 7), I have the whole day trying to solve this but I just can't:

I downlaoded the sample code accompanying the "Cascading Drop Down Control to Access a Database" AJAX Toolkit video, and added the datasets from the sample code to my application running in VS2008 and AJAX 3.5. I think the sample code is in a prior version of AJAX.
When I ran my project I used to get Method Error 500 and after 2 days of searching the web could not get a solution. Finally by chance I recreated the datasets fresh in my app using the wizard as shown in the video and the error dissapeared and the cascading drop down worked beautifully.
I have 3 table in database
1-state
Id state
1 USA
2 UK
2-City
Id name state
1 Canada USA
2 London UK
3-Region
Id regionname cityid
1 01 Canada
2 02 London
and I have 3 DropDownList that refer below thread [URL] ...
I use cascadingdropdown for these 3 dropdownlist below are codes:
AND
[WebMethod]
public CascadingDropDownNameValue[] GetCountries(string knownCategoryValues)
{
string query = "SELECT state FROM stateTest";
List countries = GetData(query);
return countries.ToArray();
}
[Code] ....
1-DDLstate
2-DDLcity
3-DDLregion
at first I should select Item from DDLsate then DDlcity and at the end I should select Item from DDLregion
above code work correctly for ddlstate and ddlcity but it doesn't work for ddlregion...
I mean when I select Item from ddlcity in ddlregion shows:[Metod error500]
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:

I am trying to populate 3 dropdown lists with using CascadingDropDown. DDLs shows make, model and color respectively. The last DDL is having AutoPostBack = true and I am trying to display the values from dropdown in one label control. I am pulling data from a webservice to populate DDLs. I am not getting any error while compiling but when I run the code it shows Error 500. I am not sure where I am going wrong. I am following the tutorial video of 'How Do I' -
[URL]
I am using C# and .Net framework 2.0. Web Service code looks like this
[Code]....
And Web Page Default.aspx looks like this -
[Code]....
I don't understand where i am getting wrong.
[WebService(Namespace = "[URL]/")]
I followed the CascadingDropdownlist tutorial: [URL] The 3 CascadingDropdown im using are working fine. But when i click on the SEARCH button it return the following error:
Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation. at System.Web.UI.ClientScriptManager.ValidateEvent(String uniqueId, String argument) at system.Web.UI.Control.ValidateEvent(String uniqueID, String eventArgument)
at System.Web.UI.WebControls.DropDownList.LoadPostData(String postDataKey, NameValueCollection postCollection)
at System.Web.UI.WebControls.DropDownList.System.Web.UI.IPostBackDataHandler.LoadPostData(String postDataKey, NameValueCollection postCollection)
at System.Web.UI.Page.ProcessPostData(NameValueCollection postData, Boolean fBeforeLoad)
at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)
Then i found this: [URL ]And now i can´t register the ASSEMBLY on the top of the MASTER PAGE.
Locally I have the cascading dropdown which loads countries in a cascading dropdown working.
But as soon as I place the code on the hosting server, Firebug shows me an:
500 Internal Server Error - [URL]
The cascading dropdown just shows "[Method error 500]"
REMEMBER: IT WORKS ON MY LOCAL SERVER!!!
local configuration:
Windows 7
IIS7.5
ASP.NET4
server configuration:
Windows Server 2008
IIS7.5
ASP.NET4
So it almost MUST be something on my hosting server! :s I dont know what to configure though...

I'am with problem in CascadingDropList, I develop in my pc and work perfectly, but when put on server show error method 500?
View 2 RepliesI have a long running PageMethod defined in the cs that is being called from javascript and after 4 minutes I am getting the below error and 504 status code for my aspx page and onFail callback is raised.

I added the extender and when i tried to add the method this message poped up; Cannot create page method "GetCompletionList" because no Code Behind or codefile was found.
View 4 RepliesI'm using a custom AJAX based validation control to check user name availability from database. It's working alright in my development machine but in production server we are using Windows Authentication to authenticate by domain.The control is inherited from base validator and checks for user name availability from database perfectly but on form submission at Page.IsValid check it gives the following error.
remote server returned an error 401 unauthorized
Both the form and webmethod are in the same page/file. I even tried creating webmethod in a separate standalone webservice but error still there.
What am I missing here; this should be straight forward, but when I attempt to access the "get_activeTabIndex()" method on my Tab Container's ID, I get the following error:
"Object doesn't support this property or method"
This is using VS.NET 2010 with the AJAX Control Toolkit built for Framework 4, but I don't think anything was deprecated so this should not be an issue. I extract the ID of the control using serverside script variables, then attempt to access the method, but it fails. Take a look:
[Code]....
Value 'tabCtrl' does indeed have value, as I can see it registers as an object (not NULL or Nothing) and ClientID resolves to the following:
ctl00$ContentPlaceHolderMyApp$AJAXTabContainerNumData
I am implementing web service into my web application, i added web reference to my application of required web methods from my asmx file.
i am able to create object of this weservice and able to see all the web methods available from the reference object. In debug mode(working environment), i could invoke and get result from the webmethod and working fine as expect. i created test page for testing this.
But, when i deploy same in my beta i am getting below error.(my both test page and asmx file available in my beta server where i deployed)

I use the CascadingDropDown to fill several DropDownList in my web to manage different application access rights
I use the Ajax CascadingDropDown component for that.
My problem is that, depending on the application, the selections criterias of the values in my database will be different.
I would like to know if there is a way to get or to identify the name or the ID of the dropdownlist which execute the CascadingDropdown class in the .asmx part (in the "public CascadingDropDownNameValue[] GetApplication1(...)" class ) ??
The name of the DropDownList give me the code of the application manage use to select my data in my SQL query
I don't want to write several query for each dropdownlist like :
public CascadingDropDownNameValue[] GetApplication1(...), public CascadingDropDownNameValue[] GetApplication2(...) etc ...
as they will be create automatically at the loading of the page.

When I type: www.domain.com, it all works.
However, when I type: domain.com it stops working and the dropdown shows: "[method error -1]"
Here's my code:

i hv been tryin since a long time..but not able to resolve my problem.M making a cascadin dropdown with ajax but gettin method error 500 in my dropdown on running it..here's my code1. dataservice.cs file
using System;
using System.Web;

[code]...
I have created a dropdown through code behind.Then created a Cascading dropdown that also through code behind.
All the properties of cascading dropdown have been initialized properly (as i think).
And web service method is defined in separate file.
DDL and Cascading DDL have been created in App_code/NewFolder through a class file. That webservice.vb file too is placed in this folder. and webservide.asmx file is placed in root directory of the project.
When i run the project dropdown is filled only with [Method error 500]. query to fetch data from database have been written in webservice.vb file without any known error.
I would like to populate Cascading DropDownList From SQL Server.
I prepare my project the same way as in this article: [URL] ....
But all the time I have "Method error 500" I read many articles how to solve this issue but without success.
Below there are my codes:
----SQL DB has two tables:
1.tblUAP (UAP (PK), Start_Date,End_Date)
2.tblGAP(idGAP (PK),GAP,UAP(FK to tblUAP))
 ---project1.aspx

<%@ Register assembly="AjaxControlToolkit" namespace="AjaxControlToolkit" tagprefix="asp" %>
....
<asp:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server">
</asp:ToolkitScriptManager>
[Code].....
----Services.asmx
using System;
using System.Web;
using System.Web.Services;
using System.Data;
using System.Data.SqlClient;
using System.Configuration;

What else Can I check ??
