Validation Groups - Server side

Ok, so I'm working through examples in the apress book "Pro ASP.NET 2.0 in C# 
2005". The Validation groups example doesn't work the way I thought it 
should.  It consists of 2 textboxes and 2 buttons and 2 required field 
validators.  One set of controls is set to validation group "G1" and the 
other set to "G2".  There is also a label to display what happens on the 
server.

The example appears to work flawlessly at the browser but results at the 
server vary.  Specifically, leave the first textbox empty and enter text in 
the 2nd textbox (group "G2" controls) and click it's Validate button. The 
page posts back and the server reports that both groups evaluate to false.  I 
had expected The "G2" contol to evaluate to true.  Am I missing somrthing 
here?  See below for the HTML and code behind.

Double check your control-to-validate property for each. Make sure
that for rfv1 its set to txt1 and for rfv2 its set to txt2. Also,
double check the validation group properties for both validators, both
buttons, and both validation summaries. You do not have to set it for
the textboxes.

I have just recently figured how to use validations groups and also
custom validators. Once you figure out how to insert custom logic into
both the client-side and server-side custom validation functions
(unless you already have), you will find that life is MUCH EASIER!!!

Re: Validation Groups - Server side

Ok, so all the stuff you mentioned to check is set correctly as you can see 
by the code I included.  Yet the server continues to return false for 
validation group G2 given the conditions I described in my original post.  So 
the question remains, is there a problem with my code, or is there a problem 
with the way validation groups work at the server?
