Another significant update to PostBack Ritalin is available today. Changes include:

v0.9 (1/30/2008)

• Resolved all remaining issues with master pages. Nested naming containers should no longer cause any issues.
• Added the ability to provide UpdatePanel specific WaitText and WaitImage properties for each MonitoredUpdatePanel.
• Added correct handling for virtual paths in all WaitImage properties.
• Added CSS to change cursor style to “wait” when hovering over the disabled control.
• General improvements to client side code.

The download is available on the PostBack Ritalin page.

I have several more ASP.NET AJAX example posts and at least one book review in the pipeline. January has just been a very busy month so far (it started with our primary web server’s RAID array crashing on New Year’s Eve, so you can imagine). Stay tuned for more of what you’re used to here soon.

A small update to Highslide JS .NET is available today. Changes include:

v0.5 (1/11/2008)

• Updated embedded Highslide JS version to 3.3.6.
• Cleaned up Alt and Title attribute handling.
• Added TitleText property to HighslideImage.
• Added LinkTarget property to HighslideImage.

The download is available on the Highslide JS .NET page, as always.

Wrapping up my series on some of ASP.NET AJAX’s less utilized client side functionality, this post will take a closer look at some of ASP.NET AJAX’s JavaScript UI helper functions. These methods are great because they abstract away most of the tedious work that comes with supporting cross browser compatibility, leaving us with a nice, consistent API.

Specifically, I’m going to show you examples of using addCssClass, getBounds, getLocation, and setLocation to accomplish a few client side UI tasks.

As of today, the site is exactly one year old. What a year it has been!

I would like to sincerely thank every one of you for making this past year such a blast. Without all of your great comments, emails, links, and kicks, I doubt that I would have been motivated enough to keep putting in all the work that it takes to run this site.

I would also like to especially thank Joe Stagner, Scott Guthrie, and the DotNetKicks community for their considerable support this year.

Thanks to Alessandro Gallo and Manning Publications, I am happy to announce that I’m going to be giving away three copies of ASP.NET AJAX in Action this week in celebration of my blog’s one year anniversary.

If you haven’t read ASP.NET AJAX in Action, you really owe it to yourself to check it out. The book does a great job of helping you understand what’s actually going on under the hood, not just the syntax of the controls. That sort of intimate understanding of the fundamentals is crucial when creating real-world AJAX solutions.

The book goes on to explain all of the ASP.NET AJAX server controls and show full examples of their use, while continuing to keep you aware of any consequences that a particular strategy might have. It also delves into more advanced topics a bit, like building AJAX enabled controls, the ASP.NET AJAX futures, and how to maintain unique URLs for intermediate points in your AJAX application’s workflow.

I don’t generally read technical books about practical application, but I couldn’t put this one down. If you’re reading my site, there’s an awfully good chance that you’d enjoy this book.

Now, on to the fun stuff. I’m going to select winners for the books in three different ways:

In my last post, I began a series exploring ASP.NET AJAX’s client side functionality. If you missed it, you can catch up by reading that post about the various uses of $addHandler.

In this post, I want to take a look at a few more under-appreciated tools that we’re provided with as a part of the framework: Base type extension methods.

Specifically, I’m going to provide some examples of using Array.contains, Date.format, and String.format.

Reader Kevin posed a good question in response to my last post, the answer to which is useful enough to warrant a separate post:

I have a situation where I call a page load handler from a script associated with a master page, then on a specific page based on that master page I need to call a second page load handler. I use the pageLoad() shortcut notation in the master page script. I can’t get either pageLoad() (expected since the composite page would have two pageLoad’s) or $addHandler(document, “load”, mySpecificPageLoad()) to work. I had to resort to my old “addLoadListener” function to add the second page load event handler. Is this as expected?

As he mentions, there’s only room in the page’s DOM for one pageLoad shortcut function, preventing both a master and content page from utilizing the shortcut simultaneously.

To work around this limitation, simply add this to your master’s pageLoad:

<script type="text/javascript">
  function pageLoad() {
    // Master pageLoad() code.
 
    // If function contentPageLoad exists, execute it.
    if(typeof contentPageLoad == 'function')
      contentPageLoad();
}

Now, contentPageLoad is executed on any content page you wish to include it on, just as if it were pageLoad. If you don’t include it on a particular content page, the conditional will prevent its execution (and subsequent JavaScript error).

You could use Sys.Application.add_Load to wire up a custom pageLoad on every single content page, but I think the DRY-ness of this approach is preferable. The above method also allows you to retain control of the order of execution, through the placement of the contentPageLoad call in pageLoad.

It’s easy to think of the ASP.NET AJAX framework primarily in terms of the server controls it provides. However, make sure that you don’t overlook the client script helper classes at your disposal. Many of them are very useful and surprisingly powerful.

In the next several posts, I’ll be examining these client side helper classes and hopefully giving you some ideas for more effectively using them.

In this first post, I’m going to take a closer look at $addHandler.
