Strange. I have a project now were I'm calling an ajax method from the onunload script event and it seems to be working fine.

I'll have to go back on what I said as closing the browser will run the code, but there are lots of cases where it won't. For instance, using the browsers back and forward buttons don't cause unload events (so if a user goes back a few pages before closing it won't run.....I don't think....), if the user has disconnected from tinternet, if the browser crashes, if you force quit the browser... It also depends on the browser, certainly IE has different ideas about when to call load events than Firefox.
I'm not saying you can't use this method I'm just pointing out that it can't be 100% relied on (as anything client-side can't be)

Yes, the event is fired.

Well of course you can't call a server-side method in this case

As with many other things. Properly coding the application to handle different browsers is necessary in any professional, robust web application.

Since your so adamant about it I had a little play around and I'm going to have to eat my words and say I'm wrong 
I guess I didn't really give it much thought in the first place, just wanted to point out to the OP that javascript can't be relied upon....it seems we both know all about that though so no point in arguing technicalities.

Let's say I've got a nice webpage layed out with some snazzy designer, but somewhere in the webpage I want some dynamic content fed by, say, XML, which will consist of some controls--buttons, grids, checkboxes, textboxes, whatever.
Sooo...what's the best practice for taking a webpage and "injecting" this content before it's served to the browser? How would the web server locate the area in which to add this content? Custom tags? A div section with a name that the web server looks for?
Is this something these newfangled technologies coming out of Microsoft can do?

I would go for a Div or a PlaceHolder control. I had used the PlaceHolder control in one of the project, the datagrid could not provide some functionality I needed and I had to write my own html table and fill it with controls dynamically, provide support for paging. I had no idea about AJAX at that time, or else I would have used some of the AJAX controls to avoid postback issues in few cases.

I think the asp panel container will do this for you. In the page_load event of the page you can parse your XML custom content and add all the controls etc to the panel by name.

Personally, I'd look at a Custom Web Control with a configurable data source that can be an Xml file or something else, having the required elements defined in the documentation of course.
Configure the data source type and path via the config file and Bobs your uncle, something entirely re-usable - just a drag 'n drop control with configuration requirements.
Some basic examples, (not my work, just quickly sampled links Googled from my home machine)...

Go to your web.config file and set the time-out for the sessionState element.
Note: the figure you enter would be in minutes!

First you need to place the panel object on your page.
Then go to the code behind and add this where necissary:
<br />
Control c = Page.LoadControl("VirtualPathToControl.ascx");<br />
<br />
panelid.Controls.Add(c)<br />
This should work fine. is this what you wanted?

A cs file has nothing to do with your web page. An inc file is not the right way to use ASP.NET.
