AJAX :: CascadingDropDown - Method Error 500

Dec 26, 2010

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.

AJAX :: CascadingDropDown ERROR 403 500 12030

May 19, 2010

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:

AJAX :: Using CascadingDropdown Generate Validation Error

Jan 31, 2011

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 canīt register the ASSEMBLY on the top of the MASTER PAGE.

AJAX :: 401 Unauthorized Error In App, AJAX Control Calling Web Method Within Same Page

Jan 10, 2010

I'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.

AJAX :: Getting Error With Method On Tab Container ID

Jul 13, 2010

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

AJAX :: Get The Name Of A Dropdownlist With CascadingDropDown?

Jun 17, 2010

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.

AJAX :: Method Error 500 In Cascading DropDown?

Jul 27, 2010

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.

Below is my code for one of my sub-categories. I want to have my sub category controls hidden and only show them if there are sub-categories (not all categories have sub-categories)

Jan 27, 2011

I'm using a CascadingDropDown in my page and I need to do the following things :

- Getting the list of elements in the dropdown

- Setting a specific value to the dropdown if it exists in the list

I am a total noob in webservices and javascript so I would like to do this in the codebehind but when I try to get the items of my dropdown, the only one returned is the one that is selected on the client side.

Is there a way to get the full list from the codebehind?

AJAX :: Using Cascadingdropdown To Update Detailsview

Nov 9, 2010

I have two sets of cascading drop down lists they are contained in a detailsview <edititemtemplate>. The problem is that when the user clicks update; the original data is wiped out and the user has to redo the selection of all items contained in a cascading dropdown even if the user didn't want to change that particular aspect of a record. If the user doesn't select everything an error is thrown by the stored procedure in regrds to null values not being valid.

Is there a way i can use cascadingdropdown so that the current values are visible when the user clicks update; meaning that they don't have to redo selections for all items involving drop down lists. The current selections would be default values.
