Exposing Web Services from an ASPX page does not work

Hi All,

I am working with ATLAS technology. i am trying to imitatehttp://atlas.asp.net/quickstart/atlas/doc/services/default.aspx#webpage
"Exposing Web Services from an ASPX page"

i am having an aspx page which is inherited from our own Page class not from System.Web.UI.Page.

public partial class MainSearchPage : some namespace.MyPage

but this example does not work in this context.because in javascript, function OnWebRequestComplete1(result) returns null as result.

please help me in this issue.

thanks

hello.

well, i think that it should work. here's an example:

pypage.cs
namespace Test
{
public class MyPage:Page
{
[WebMethod]
public string HelloWorld(string s)
{
return "Hello '" + s + "'";
}
}
}

now, the aspx page:

Untitled Page

function handle()
{
PageMethods.HelloWorld( "Luis", handleComplete );
}

function handleComplete( res )
{
alert( res );
}

here everything is working properly...

Yes, this should work. To debug your issue, I would try:

Check on the server whether your method gets called at all.

yes, my server side code in code behind of aspx is not getting called.
in javascript side:

function handle()

{

PageMethods.HelloWorld("jaideep", handleComplete );

}

function handleComplete( res )

{

debug.dump(res,"Result",true);

alert( res );

}

in debugger, result is null.also my aspx is having one user control also.i tried to put debug in my code behind.but function HelloWorld is not getting called.

any clue as to what is happening.
thanks

after viewing request/response in Fiddler ,i got a message indicating a corrupted viewstate.
same is the problem in following post:
http://forums.asp.net/1205269/ShowPost.aspx "ViewState and Atlas ".
and as per the instruction given , i removed "type =="hidden" condition from file
Atlas.js on line 3495.and now it is working!! but this approach is correct or not?
please let me know about this.
Thanks

Copying my reply from the other thread:

I tried a few things, but was not able to repro. Could you give this a try with the March CTP to see if it still happens?

thanks,

Exposing Web Services from a custom control

In one of quickstart tutorials there is a way to use a WebMethod straight in the aspx.page(http://atlas.asp.net/quickstart/atlas/doc/services/default.aspx#webpage)

<%@dotnet.itags.org. Import Namespace="System.Web.Services" %
...

<script type="text/C#" runat="server">
[WebMethod]
public string HelloWorld(string s)
{
return "Hello '" + s + "'";
}
</script>

This example calls

PageMethods.HelloWorld(document.getElementById("nameTextBox").value, OnWebRequestComplete1);
on the client side

I am developing custom controls and am wondering if I can call a WebMethod from within my custom control.

I would imagine I have to register the namespace and class of my custom control but I don't know how. It obviously works on the aspx page because of the built-in PageMethods function

IMHO, you can't do this in the current version of Atlas because the Atlas Server Library doesn't provide this future. It will be necessary to look through control tree searching special methods... And Atlas must have an ability to know, which instance of webcontrol was called by client script. It's very difficult, as I think.

Exposing Web Services defined in class libraries

I have a class library (or will have) that defines a bunch of web services. I can reference Atlas if necessary. How do I expose all these web services to Atlas via IIS/ASP.Net. In other words, I do *not* want the code for my web services to be in the web project, I want them to be in an external project and optimally just included with a single line for all services, or a line per service if necessary.

Thanks.

All you need to do is to add your assembly as a reference to the web project and then add it to the ScriptManager service reference as following:

 <atlas:ScriptManager ID="ScriptManager1" runat="server" > <Services> <atlas:ServiceReference Type="namepsace.typename" /> </Services></atlas:ScriptManager>

Replace the bold text with the type name of your web service.

Seems that this has changed since way back when... How do I reference a service in a class library now? How do I then hook it up to an extender, e.g. an AutoCompleteExtender?

Thanks.
