Infragistics Offers .NET Developers First UIElement for Avalon Framework
Written by Infragistics at the request of Microsoft, UltraGrid for Avalon was showcased at the PDC. The technology demonstration is an example of what could be done in a very short period of time by leveraging the Avalon framework. The control was written from scratch in less than one month's time by two Infragistics developers who had no prior exposure to Avalon. This was made possible by the fact that the Avalon's framework and Infragistics' Presentation Layer Framework (PLF) are remarkably similar - both are based on UIElements and visual trees.

Few thoughts on debugging
Maybe this will help somebody now or in the future.
I was working on some dynamic dropdown lists (3 exactly) interacting together and some databinding.
You know you choose a menu and the other ones populate in function of the first one.
Easy? Yes and no.
I had some bugs coming randomly about the fact my code was trying to select multiple elements in one of the dropdown.
My point here is that whatever I could do, Try..Catch was not able to trap the error.
Apparently the problem come because the dropdown is render by .Net only at the end (HTMLTextwriter). So of course you have no idea which line in your code create the wrong statement.
Annoying because I had no way to identify the issue.
So my modest advice if this happens to you, transform your dropdown as listboxes object.
You will be able to set the selectionmode as multiple and magically your code will work, exposing clearly then the faulty multi selection on one of your lists. -
About posting and code
Just to avoid the long posts (interesting anyway) and the long code listings (like some today ;-) , can we all be agree to use the Articles features we have on this blog ?
I think , and it's just my opinion, the main feed should show only short posts, announcements, and eventually some links to a more explicit article.
What do you think ? -
The XHTML Way
Introduction
If you're starting a new Web project or enhancing an existing Web site, you face the same dilemma: Which version of HTML should I use? Many developers shy away from the latest Web standards because they think it's an either/or choice and aren't ready to commit 100% to the new standards. This article will give you the background you need to make an informed decision and show you how you can gradually transition to the latest Web standards by successfully combining HTML 4 with the latest XHTML.

Irish .Net Bloggers
Just reading the post from Jan Tielens about the Belgian .Net bloggers and this give me an idea.
What's about an Irish .Net bloggers feed. I have some webspace somewhere so eventually I could easily setup a such thing. -
Code Library
I use Code Library since few days now, and it's really a must-have tool for all developers, .Net or not
Now I discovered that I can almost store anything in the SQL database, so I am actually starting to implement my browser favorites.
Just because Code Library has an integrated browser, and a node system to let me organize better than ever my best pages.
The fact that everything is in one place give me also a breeze, and I can now think about a backup of one database. -
Selectutorial - CSS selectors
Selectors are one of the most important aspects of CSS as they are used to "select" elements on an HTML page so that they can be styled.

Great resources page
Keep this in your favourites.
I am testing Code Library and I just found a great resources page on their site (.Net, DHTML, XML, Database, Forums, etc...).
Useful to find some snippets to add to your Code Library database
