[How Do I:] ASP.NET AJAX Enable an Existing Web Service?

Please install Silverlight or click download to watch video locally.

This video demonstrates how simple it is to add Microsoft ASP.NET AJAX functionality to an existing ASP.NET web service. This enables the web service to generate a JavaScript proxy that the client browser can use to call the web service.

Hi Joe,

Your example worked great!  but as soon as I created a separate project for my webservice I ran into issues.   It appears that I am not getting a resolveable path for my asmx file.

typically it would be something like

Path="WebServiceName.asmx"  

If the webservice resides in same project but I have it in another project whose name is wsNorthwind and the webservice is NorthwindJS.asmx.  So I figured this

Path="~/wsNorthwind/NorthwindJS.asmx"  I get an error that says NorthwindJS is undefined.

I also tried envoking it as wsNorthwind.NorthwindJS.SayHello with no success?!

What gives??

Joe, it seems your example fails in FireFox and Google Chrome. What would cause this?

Great tutorial though! Thanks!

Hi Joe

I do have same problem as "aarturo".

I am not able to call my web service which resides outside of my current application. Any Idea on that...

Will this work if my webservice uses a database to retrieve the data?
