Ajax.NET Professional Beta 5.11.24.1 available

I posted a new version to the Google group [1]. Attached you will find a beta version of the next version. I had to recode a lot of parts to get the queue working correct with 2 http connections. Now, if you add this assembly you have to be careful if you use inheritance from the AjaxPro.AjaxRequest. You have to inherit from AjaxPro.AjaxClass instead, now.

XmlHttpRequest not working

The last weeks I done a lot of test because of the memory leaks using .innerHTML or events (closures). When building some test pages I ran into a problem. I reached 65.000 handles for iexplore.exe. From time to time I got a dialog box asking if I want to send data to a different location (the same question you get if you post data to a different domain). I clicked on yes, I clicked on no - both buttons are working, and my AJAX method, too. But some requests later I got the dialog box again, ...and again.

Using WITH(...) in JavaScript

Some days ago I had a look in some Visual Basic source code and found the WITH statement there. I was thinking about how I can use this in JavaScript code. Below you will find a very simple script that allows you to use the With method (that will reduce your source code size of JavaScript files):

Ajax.NET Professional and the "missing" context

I had done a lot of changes to the JavaScript methods. With the new version I had removed the context that you could provide to have something like a "this" context.

More controls for Ajax.NET Professional

I get a lot of requests for new controls that are using Ajax.NET Professional [1]. Some don't want to use other controls, they are searching for the best (or right) way to develop such controls. I have added some examples already to my web site at http://www.schwarz-interactive.de/ [2]. Because AJAX controls and web sites have to be developed different to current web applications I will create some more examples.

An simple AjaxButton using Ajax.NET Professional

I have created an simple AjaxButton that will only call a method on the server-side code. There are no values sent to the server or back to the client. A new AjaxButton could serialize the form and send the data to the AjaxMethod.

this.method() and base.method() in JavaScript

I looked around for the problem when you want to inherit from a JavaScript "class" with overriding a method, but I didn't find any solution. Today I tried this, which is working, but not very nice coding:
