I am having some trouble understanding what the ASP.NET validation controls actually do.

Do they validate on the client, the server, or both?

I understand the customvalidator has an event called onServerValidate which can be used to trigger server validation.  

But what about the requiredfieldvalidator, rangevalidator, etc, etc.  There is a setting that says EnableClientScript.  I have set this to false and have mixed results.  In some cases the validation doesn't work anymore and in other cases it works fine.  

I don't know if I should be creating client and server side validation routines.  If so, how do I do both at the same time?
