Need help with DynamicPopulate and WebService

I'm having a bit trouble getting this to work... I've made a very simple WebService, tested it etc. Everything works fine, I can even call it 'from a normal website as usual', but when I call it from this Extender I keep getting an error:

WebService call failed: 500

This is a snippet from the Extendersetup:

<

atlasToolkit:DynamicPopulateExtenderID="dp"runat="server">
<atlasToolkit:DynamicPopulateProperties
TargetControlID="Panel1"
ClearContentsDuringUpdate="true"
PopulateTriggerControlID="Label1"
ServicePath=http://localhost/wstest/service.asmx
ContextKey="kkl"
ServiceMethod="GetHtml"
/>
</atlasToolkit:DynamicPopulateExtender>

And from the WebService:
[System.Web.Services.WebMethod]
publicstring GetHtml(string contextKey)
{
System.Threading.Thread.Sleep(250);
string value ="";
if (contextKey =="U")
{
value =DateTime.UtcNow.ToString();
}
else
{
value =String.Format("{0:" + contextKey +"}",DateTime.Now);
}
returnString.Format("<span style='font-family:courier new;font-weight:bold;'>{0}</span>", value);
}

Everything is just taken from the samples, but exposed like a WebService.

Any good ideas with this can be??

Kind regards

Make sure you have the webservice stuff in your web.config. The easiest thing to do is to make sure you're starting with a new "Atlas" Website, since it's already set up. If not, I think this is all you need:

<

configSections>

<

sectionname="webServices"type="Microsoft.Web.Configuration.WebServicesSection"requirePermission="false"/>

</configSection>

<

microsoft.web>

<webServicesenableBrowserAccess="true"/>

</microsoft.web>

I've all that in my Web.config - I used the Atlastemplate when I started the project. I've also updated all Atlasfiles to the latest versions.

I've just tested the AtlasControlToolkit and DynamicPopulate and the testharness, i've added the ServicePath right between these:

TargetControlID

="Panel1"
ServicePath=http://localhost/wstest/service.asmx
PopulateTriggerControlID="Label1"ServiceMethod="GetHtml"

Page Method Update:

WebService call failed: 500

Script Method Update:

Script Success

var PageMethods = new function() {var cm=Sys.Net.PageMethod.createProxyMethod;cm(this,"GetHtml","contextKey");}

But still an error... Could there be something wrong with the WebService? An Error 500 is a bit hard to work with. For developing the WebService I just took the ASP.NET WebService-template. I've uploaded the WebService in a folder under the Default Web Site, as you can see in the servicepath. As I mentioned earlier the WebService is working fine if I just manually inputs the path into the browser, also I've checked that the WebMethod satifyes the required signature!

Kind regards

i had the same problem with ajax-toolkit and cascadingdropdown-extender (which is calling a local webservice).

--> WebService call failed: 500

as soon as i deleted the attribute enableBrowserAccess="true" inside <webservice>-section, everything worked as expected. !?
