Hi
Even though I am developing using 3.5 I am using this book to learn about Server Controls.
Using Chapter 5 and 6

I am trying to implment validators and i keep getting an error
"Unable to find Control Id "creditCardNoTextBox " referenced by the controlToValidate property of my "reqCreditCardNoTextBox"

This is what I have done
Added a RequiredFieldValidator creditCardNoRequired
Added CreditCardControlContainer creditCardNoValidatorContainer
Added a ContainerType.CreditCardNoValidator
Added a case to CreateContainerChildControl to include CreditCardNoValidator
Added to ApplyContainerStyle
Added to RenderContents

case ContainerType.CreditCardNoValidator:
creditCardNoRequired.ID="reqCreditCardNo"
creditCardNoRequired.ControlToValidate="creditCard NoTextBox"
creditCardNoRequired.Text="Required"
creditCardNoRequired.Display=Validator.Display=Dyn amic

container.Controls.Add(creditCarNoRequired)


What Am I doing Wrong?
Can you help?
Thanks a lot
