I was building a page today that allows an admin to do some configuration and doesn't save anything back to the server until the admin chooses. I could have used XML or a temporary SQL table, but I choose ViewState for now. I continually received the error: Type 'MyNamespace.MyClass' in Assembly 'App_Code.gvg30s8w, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null' is not marked as serializable. Of course the error spells out what's wrong. But, because I was still flustered with my earlier issue, I didn't read into it far enough. Again, a search online turns up almost nothing. Finally, the light came on. To get it to work you will need to add the <Serializable> (in VB) or [serializable] (in C# to the beginning of your class. Well, back to the grind.

Create browser-independent gradients dynamically with an ASP.NET IHttpHandler

a javascript module that grants developer to select variant parts or may be the whole page to make user can print preview it and print it.

Here is a great video that provides some insight into the impact of Scrum at Google.

Silverlight 2.0 (1.1 alpha) introduces powerful new features that could revolutionize web development and Visual Studio 2008 makes them easy to use.

This tutorial examines the new Visual Studio 2008 Server Control and Server Control Extender. A compendium of tips, tricks and gotchas, it is a comprehensive tutorial that will provide readers with the skills necessary to start building advanced AJAX-enabled custom controls with Visual Studio.

Yet another list pager, but this one can use LinkButtons or simple hyperlinks, provides scrolling within an ASP.NET Ajax UpdatePanel, and behaves similarly to the paging found on Amazon.com.

I'll be speaking on the topic "LINQ: Simplifying Data Handling in ASP.NET" at the Victoria .NET CodeCamp on January 26th. It's going to be a great (free!) day with expert presenters that include Beth Massi and Richard Campbell . Here's the abstract for my beginner-level talk: Language Integrated Query (LINQ) is a "learn once, use everywhere" language addition to VB and C# that makes it easy to query, sort, and filter .NET collections including SQL Server data.

An application for users to play Circular Chess over the internet based on Silverlight, ASP.NET Ajax, WCF Web Services and LINQ to SQL

Like every other day, I'm blowing through some really complex code trying to create hacks to get around difficult issues. Then, a road block. I have a mind freeze and oops, I forgot what the issue is. I had that earlier today when I forgot how to access the item index number in an ItemTemplate of a DataList or Repeater. I pinged the aspadvice.com lists and Ryan Trudelle-Schwarz responded (although he forgot the big Duh! on the top) to use the Container.ItemIndex. Low and behold, adding this: <%# Container.ItemIndex %> to your code does spit out the Item Index number. After a good hour or so of searching MSDN trying to find it, Ryan came to the rescue. Thanks again Ryan for kick starting my brain.

Last year I presented on Team Based Development at TechEd - I found a link to the recorded presentation today.  You will be prompted to download the video.

This article builds a web based message board and uses several new technologies introduced with Visual Studio 2008 such as LINQ, WCF Web Programming, WCF Syndication, ASP.NET ListView, ASP.NET DataPager etc

NewsFactor - On Thursday, Netflix and LG Electronics said they are joining forces to develop a set-top box for consumers to stream movies and other programming from the Internet to HDTVs -- bypassing the need to use a PC.

AP - DVD-by-mail service Netflix Inc. will begin delivering movies and other programming directly to televisions later this year through a set-top box that will pipe entertainment over a high-speed Internet connection.

I finally got my hand on a HTC Touch.  Yes, it's not an iPhone but I the iPhone is not available in Canada yet and I absolutely need to sync from Exchange.

I also switched from Rogers to Bell Mobility because of the outrageous cost of Internet access at Rogers (and most Canadian carriers).  Bell is now offering unlimited Internet access for a mere $7/month!

Yes, Bell is CDMA not GSM and that sucks but from by good friend Barry Gervin recommendation, if I go to Europe, I'll just bring with me an old GSM phone and I'll buy a cheap pay as you go GSM card.

One nice thing about the unit offered by Bell is that the processor runs at 400Mhz instead of 200Mhz.  What's sucks is that it doesn't have WiFi but with unlimited Internet access, who needs WiFi  ;-)

I was also amazed at how easy it is to set Direct Push from Exchange...well, there's nothing to do if you already have OWA configured.  Nice!

Bell was also including for free a set of Altec Lansing T515 BlueTooth speakers/headset and a 2GB microSD card.  Good deal!

Robert Scoble annoys me. I used to enjoy reading his blog, but it has gone to a point where he really thinks he has all the answers and is the smartest blogger on the Net, masked thinly by the occasional self-deprecating comment or whatever.

But now he got booted off of Facebook because he was using an automated script to take all of the contact information from his 5,000 friends and dump it into Plaxo. Are you seeing the irony here? This is the same guy who called out Zuckerberg at Facebook for screwing with people's privacy and not owning up to it. Are you kidding me?

Here's the big news flash, Scoble... I added you as a friend to see what you were up to, not so you could suck out even my name and e-mail and put it in some other system. Why do you think I'd be OK with that?

Facebook should drop you out on your ass. You screwed up. Now admit it, the way you expect everyone else to when they screw up.
