@digitalhost: Yes, of course. I fixed some bugs yesterday and added some new features. Now, I will go on with the unicode problems. Check this blog later...

What's the license terms for your Ajax wrapper? We've been using our own in umbraco (GPL Licensed) for some time, but maybe it's better to use the one you've made...?

# re: Ajax.NET - new release with Usage Guide

There is no license at the moment. The Ajax.NET Wrapper DLL will be free with no warrenties. Support is available by email... You can use the Ajax.NET Wrapper for all your projects but it is not allowed to redistribute it as a standalone lib!

# re: Ajax.NET - new release with Usage Guide

I don't see any usage guide in the zip file you link, only the dll.
Also, the demo video is nice, but it would benefit a lot from being shortened and have some audio commentaries.
Cheers,

Yes, the problem is that time is missing.

The usage guide can be found at: http://ajax.schwarz-interactive.de/download/AjaxGuide.doc

# Ajax.NET - new release with Usage Guide (via Sean McCormack)

I found this link on Sean's blog. There is a new .NET library for doing Ajax (Asynchronous JavaScript + XML) from Michael Schwarz. Here is a definition for Ajax....

# Problem running example

Hello,

I am attempting to get AJAX working on our site. I have added the handler to the web.config. I have referenced the dll. When I call the method register types for ajax method I get the below error.

Any help would be greatly appreciated. Thank You

# re: Ajax.NET - new release with Usage Guide

@Tony: You have to use Ajax.Utility.RegisterTypeForAjax(typeof(WebApplication1.WebForm1)); insteaf of this.GetType().

This is because ASP.NET will generate Assemblies of the ASPX files. If you use this.GetType() you will get the type of the new created and temporary available class. See the examples at my web site.

# re: Ajax.NET - new release with Usage Guide

Hello again,

I did as you suggested and I still get the same exception. I was able to get your sample C# project working. But, when I add AJAX to my current web project, I get the same exception as I stated earlier.

However, when I add the two script tags explicitly to my page instead of calling the RegisterTypeForAjax method, everything worked fine.

Some information that may help track down why this is occurring:
Not that it should matter, but my page inherits from our custom page class which in turn inherits from the System.Web.UI.Page class. Also, my site is all https. I don't think these two things should effect your method.


I would be happy to attempt to debug this, if I had the source code. I would contribute my findings back to you. My email address is tcastellano@minitab.com, if you want to contact me directly.

Thanks in advance for your assistance,

Tony Castellano
