You need to wire up the javascript call on the server side. You will only really be able to get the client ID on the server, where all that information is readily available. Something like the following:
void Page_Load(...)
{
chkMyCheckBox.Attributes.Add("onclick", "jsVerify('" + chkMyCheckBox.ClientID + "')");
}

could somebody explain to me why on earth you would use a listview control (or almost any other asp:xxx control) on a web page?? i looked at using it just now and am frankly astounded at how much garbage there is just to draw a table on a page??? what on earth does it do that i'm not seeing??
genuinely could somebody please explain?
thnx

Basically you may use ASP controls to render content dynamically.
In a few simple words, suppose you want to render a table with data from a DB. You cannot use a static HTML table with X rows, because you don't know how many rows you have in DB to display.
Simple options here are: to use <asp:table xmlns:asp="#unknown"> control, which can be dynamically rendered, you may add rows, columns, etc..using code behind(C#, VB), or, second option, to render HTML tags dynamically, but in this case you don't have managed support (let's say for each row from DB you'll add a < tr > tag).

ok i get that ... let me point out that i have been writing (and teaching) db driven websites for 6+yrs in python and php so i know exactly how to render dynamic content to html or xhtml
my question was meant to be more like ... what does the asp:listview give me (apart from a whole bunch of overhead) that rendering clean html directly doesn't?
thnx

ok, then.
It gives you a lot of features like: dynamic rendering, binding, custom templates, insert/edit/update modes, integrated pagination, integrated sorting...

but with a huge overhead and complexity that depends on a 3rd party (in this case MS) getting it all working correctly and rendering properly
when it's very easy to do all those things without all the extra layers and overhead
that was why i was wondering what asp:xxx controls bring to the party and who they are aimed at?

I think you might get on better with the ASP.NET MVC framework - It's a lot cleaner.

ahhhhh cool ... i'll take a look at that
thnx

wow that looks cool ... url rewriting is built in

WinForms controls are designed for people who don't know, and don't want to know, anything about HTML. The same people who managed to write Windows apps for years without ever knowing anything about Win32. They are, IMHO, worse than useless if you actually need or want some control over what's actually sent to the client.
As Colin suggests, you'll probably be much happier with the MVC stuff.
