This might help with referencing controls inside naming containers (be sure to read the suggestions in the comments too): http://encosia.com/robust-aspnet-control-referencing-in-javascript/

Ok, I figured it out by adding the `ScriptReference` to the `ScriptManager` as you mentioned in your article about "Sys undefined error." Last question: How do I get this to work for things like `GridViews` which use naming containers rather than specific IDs, hence making the `$get(args._postBackElement.id)` & `$get(sender._postBackSettings.sourceElement.id)` calls return NULL.

Biscuits! I can’t get it to work. I’m using a custom version of the 960.gs and have a “container” element called “container_20″ so I updated your code to reflect that simple replacing the name. I’m programming in VB/ASP .NET. I tried implementing your jQuery only both inside and after the “pageLoad” event. Any ideas what may be the cause? I’m sure there’s some caveat to this code that I’m missing. Thanks :)

Thanks Dave! I’ve been looking for something that works with AJAX in the 4.0 Framework, and this fits the bill. Easy, and slick… :)

Great stuff! This idea is so simple I can’t believe I’ve never thought of this or seen it before! I really like that it flows with a convention people already understand.

I’ve just found your blog and I’ve gotta say every post I’ve read is excellent. Well written, interesting, and unique. Subscribed!

Finally! Somebody addresses this obviously too-long missing behavior. Kudos.

What follows is not a slam against your article, rather a trip into the “obvious”…

For decades, in tools like Delphi, and for desktop applications, the developer had to do only this:

Screen.Cursor := crHourglass;
// Potentially long-running code here
Screen.Cursor := crDefault:

I would suggest that our web development tools, frameworks, whatever, should make it equally easy on the developer. This behavior is virtually an unstated requirement for all desktop apps, so why should web development make it any harder to achieve?

Yes, I understand there are complexities beyond desktop applications. I simply think those should be overcome in the implementation of the frameworks and languages we use for web development.

I add a class on the body tag

body.loading * { cursor: wait !important }

and then remove it when loading is done, but in IE and Chrome it does not change back until i move the mouse.

Anyone experiencing this problem, and maybe found a solution ?

Dave,

Please see below small correction in EndRequest call. I was getting javascript exception related to index without if condition.

if (sender._postBackSettings.sourceElement.id.length > 0) {
$get(sender._postBackSettings.sourceElement.id).disabled = false;
}

Your code worked like a charm except for the disable button javascript which errored for me.
But my problem is I am using an link not a button.
And when the cursor is over the link, it shows the hand regardless, only when you remove it from the hovering above the link , do you see the hourglass.
Any ideas on how to solve that too?

Great article. Just what I was looking for.

The body solution worked better for me.

Note, a good standard to use is a css global reset like this:

* { padding: 0; margin: 0; }

You can now have the body fill the screen with the following additional css:

body { width: 100%; height: 100%; }

The above replaces the css supplied by Dave and reduces the implemtation. Also, you dont need the container div. Make sure you use the change to the javascript by “Anonymous”

This worked with master pages too.

I discovered this when on a test page i did a:

body { style="border: 1px solid black;" }

… and found the body was only the height of my last element on the page.

thank you for a great solution Dave. I subscribe to your rss feed.

(hope the css i supplied posts)

Hi,
article is really great .but in my case i am using
asp.net 2003 with Ajax and i think it wont support
“var prm = Sys.WebForms.PageRequestManager.getInstance”
means there is no class with Sys.

any clues???
