use cascading dropdown in Dnn module result to Method Error 500 

  I am using Microsoft Ajax beta in dnn, but when I use cascading dropdown in a Dnn module,

It compile okay,but dropdown you find the result display Method Error 500.

I have create a webservice virtual root.and I have test http://localhost:1111/IDCardWebService.asmx?op=GetDropDownAreas. It's display okay. result like following

<?xml version="1.0" encoding="utf-8" ?>

- <ArrayOfCascadingDropDownNameValue xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://tempuri.org/">
- <CascadingDropDownNameValue>
  <name>CityName</name>
  <value>110000</value>
 
In Ascx I wrote down
 
            <ajax:CascadingDropDown ID="CascadingDropDownProv" runat="server" TargetControlID="DropDownListProv"
                Category="Make" PromptText="please select " LoadingText="Loading"
                ServicePath="http://localhost:1111/IDCardWebService.asmx" ServiceMethod="GetDropDownAreas" />
 
I have test another way
            <ajax:CascadingDropDown ID="CascadingDropDownProv" runat="server" TargetControlID="DropDownListProv"
                Category="Make" PromptText="please select " LoadingText="Loading"
                ServicePath="IDCardWebService.asmx" ServiceMethod="GetDropDownAreas" />
 
before I test I have copy a IDCardWebService.asmx file to dnn root. result was same.
 
Who could help me. thank you !

Re: use cascading dropdown in Dnn module result to Method Error 500 

I found the course.

First :

    I shouldnot use Prefixion "http://localhost:1111"

Second :

   I wrote wrong web.config.

Re: use cascading dropdown in Dnn module result to Method Error 500 

Hi skygui can you help by explaining what you did wrong in the web.config file. I am implementing the CascadingDropDowns in the AJAXv.1.0 and DNN 4.5. The dropdown values are showing Method error 500. Could you outline your solution?

Thanks

Re: use cascading dropdown in Dnn module result to Method Error 500 

You can try this:

<add verb="*" path="*.asmx" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />
      <add verb="*" path="*_AppService.axd" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />
      <add verb="GET,HEAD" path="ScriptResource.axd" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" validate="false" />

paste these lines (and remove the old ones) into:

<system.web> -> <httpHandlers>

Re: use cascading dropdown in Dnn module result to Method Error 500 

Thanks dadvir,

However I had these lines already in the web.config file.

I think that the AJAX Cascading drop downs are not working with the 4.5 DNN relerase
