Cascading Dropdown Web Method Issue



I am having an intersting issue to which I have found no solution, obviously. I am using a web service to populate a couple cascading drop downs. Evereything looks correct to me but I am getting a [Method Error 500] when I run it all. I have the <System.Web.Script.Services.ScriptService()> added to the web service so that's not the problem. What I have found while playing with it is that if I remove the arguments from the web method (ByVal knownCategoryValues As String, ByVal category As String) then it works. This of course is not helpful as I am trying to populate multiple drop downs. I can find nothing on anyone else having this issue.

I am using .NET 3.5 and Ajax DLL version 3.02... 

Also of note is that I have another website, using the same .NET and Ajax versions and this code is working fine.

I have tried everything I can think of, including my last resort tactic of smashing my face on my keyboard, and nothing is working. I am at a loss. Any help would be appriciated. Thanks.

Jscript error: Object does not support property or method


 Hi, i have little knowledge on javascript but i need to use this code get from somewhere for a jquery to work.

I face this "Jscript runtime error: Object does not support property or method" whenever im trying to run this page.

In my experience, im get this error msg 9 out of 10 times i use javascript in my system.

Im using Microsoft Visual web developer 2008, i wonder if this is related to my problem, i not sure there is anything i need to add as reference or update anything.

But anyway, in short, i just couldn't use javascript code when using this development tool because of this sort of error.

Anyway, it happen that last time i tried use the same type of jquery code in another project and it seems to work well without an error.

But now when im try to use it again in this recent project i created, it come out with this error and i have no idea how to solve it even look through google and this forum.

It doesn't really seems like its the code problem itself although im not sure, because any javascript code just couldn't work.

So below is my code that i need to use.

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js" ></script>
<script type="text/javascript" src=&quo

Issue in Infopath 2007 browser form - cascading dropdown using owssvr.dll filter view


Referring the below link, I created a cascading dropdown. The parent dropdown has sharepoint list as datasource and the child dropdown has xml datasource that points to owssvr.dll filter view. The cascading drop down works fine in preview but throws error after publishing as admin approved form - "form cannot run the specified query" exception when trying to execute xml datasource i.e., when a value is selected in parent dropdown. The security is 'Full Trust". In the event viewer the error message states "401 unauthorised" for the user a/c. the xml data source is an approved udcx file and in central admin, have enabled cross domain for infopath service. I have tried different solution provided in tech forums but issue still exists. Not sure whether Im missing something. Can someone guide me in fixing this issue?

Cascading Dropdown Question



I have 2 parent child cascading dropdowns on my form. At present they work as normal so you can only select a value from the second once you've selected one from the first, otherwise it's disabled. Is it possible to show all values in the second if you haven't selected anything from the first? Does that make sense?

ASP.Net Dynamic Data - DropDownList Field Template with AJAX Cascading DropDown Extension

Hi all,   Have spent hours trying to create a Dynamic Data Field Template holding a DropDownList which is extended by the AJAX Cascading DropDown extension. Final form holds multiple cascading dropdown boxes. User selects Country (Land) then Postcodes, Counties (Provincie) are populated. Once postcode is selected then towns (Plaats) are populated.  The problem I am now facing is that the viewstate for the dropdown lists is not being saved/restored after an insert action or custom validation error. So basically the dropdown lists are being reset to their default values. Some code (if missing parts, just ask and I will post them) - Don't mind the code structures etc... needs some refactoring :) Attribute I created:using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace Data { [AttributeUsage(AttributeTargets.Property | AttributeTargets.Field, AllowMultiple = false)] sealed public class CascadingDropDownParametersAttribute : Attribute { //public string TargetControlID; // The ID of the DropDownList to populate. public string Category; // The name of the category this DropDownList represents. public string PromptText; // Optional text to display before the user has selected a value from the DropDownList. public string
