I have developed a custom validator for checkboxes and checkbox list
required validation.

The problem I am having is that I cannot figure out how to change the
event that fires this validator. I want it to be the onclick, but
instead it seems to do it on the onblur.

Would I need to modify the Hookup scripts, or is there an easier way
to do it?

Any response would be greatly appreciated!

Thanks

You need to attach it in the rendering of the CheckBoxList which in practise 
mostly means custom control derived from CheckBoxList. Basically you need 
PoistBackOptions class instance, passing it the reference to the CBL and 
setting PerformValidation and ValidationGroup properties respectively. Then 
get the script by passing PostBackOptions instance to 
Page.ClientScript.GetPostBackEventReference. After that you have the script 
which you'd need to attach to the onclick. You certainly could do that on 
the Page to avoid custom control but that means some "glue" code on every 
page, the things is used on.

Thanks Teemu,

Do you have any examples of any of this?

I have some of the idea implemented into my sample how to cause a poostback 
on main poage from a popup

http://aspadvice.com/blogs/joteke/archive/2005/06/15/2340.aspx

It utilizes the idea by generating the script call to Emulate as if the 
Button would be clicked while the popup is closed. Difference to your 
situation is that you need to set the properties of PostBAckOptions I 
mentioned, in order to make it call validation functions at client-side
