validation within createuserwizard

[chitgoks]

hi,

i am successful in displaying error messages in my validation summary
from within a wizardstep by specifying startnavigationtemplate's
buton's property to causesvalidation="true".

i can't figure out how to do the same thing to a createuserstep
control. how can you gain access to the "create user" button? because
i would like to call the causesvalidation property to it so it can do
validation in the createuserstep page.

thanks
