non bubling events

Hello all,

In IE, when an event occurs, as long as it returns true, and
cancelBubble is not set, the event will bubble up through the elements
in the DOM tree.

Though, there is at least one event that does not bubble... the onLoad
event.

For instance:
<BODY onLoad="alert(' body onload')">
<IMG src=img.gif onLoad="alert(' img onload');">
<SCRIPT>alert(" TEST");</SCRIPT>
</BODY>

will show : "img onload", "test", "body onload".

This prooves that the onLoad event did not bubble, even if true is
returned and cancelBubble == false.

Of course, this makes sense. Just because the image has loaded, does
not mean that entire page has loaded.

So, here is my question:
In what other cases are events not bubbled? Is there a pattern? Or is
this the only case?

Thanks,
Brian

For IE, check the docs at
http://msdn.microsoft.com/library/de...nce/events.asp
they tell you which events bubble.

For DOM compliant browsers, check the W3C DOM Events specification at
http://www.w3.org/DOM/, it also lists which events bubble.

Hi. I'd like to trap ADO Recordset object events in my ASP script (either VBS or JS, no preference). I've tried (in VBS) writing a Sub rs_RecordChangeComplete( adReason, cRecords, pError, adStatus, pRecordset ) - rs being a server-side ADODB.Recordset object - but it doesn't get called whenever rs is moved (I browse it in a loop). Is there a way to catch those events from ASP?

Hi! How can I unregister all the events registered to a control? I have seen a piece of code in another thread, which gets all the registered handlers for a specific event. Let's say I have a CustomTextBox : TextBox, which has quite a lot of events... Do I put unregistering code for all the possible events in the Dispose method? Or is there another way?

Hi I use the following syntax to have events inherited from base to child classes which works nicely (virtual and override keyword on events). But I am wondering if it is a "supported" way of using events since I never saw it used anywhere in MSDN documentation/samples?! Or it will just break when I upgrade to .NET Framework 2.x in the coming years namespace MyNamespac public delegate void MyDel() public class MyBase public virtual...

Hello! I am still transitioning from VB.NET to C#. I undertand the basic concepts of Delegates, more so of Events and somewhat understand AsyncCallback methods. But I need some clarification on when to use one over another? If anyone could provide any additional info, your comments, best practices, any good articles, specific examples, etc. Thank you

Hello, I'm studying a book on VB.net Win apps, and I'm reading a section on events and delegates and raising events. Is it just me, or is this not just subs dressed up as something else? I mean, for one, delegates point to subs, so when you call a delegate, why not just call the sub dierectly and not bother adding the extra code involved adding the delegate?
