Hi.
I'm having a difficult time with user controls.  I'm developing an 
asp.net/vb application that uses multiple forms that change according to 
user selections.  The main part of the form is a user control (used by all 
users) that has a radio list, calendar control, and a text box for time, 
and a submit button that is set up for validation on these controls.  

The problem I have is that within this user control I have another user 
control that only has a single dropdown list and utilizes a component 
class .vb file for database connections and code behind to popluate it 
with data from a table.  After the data is bound to the list I insert 2 
items manually ("Please select ....." This has a value of 0, and a blank 
space with a value of 1).

I need to validate that the user control with the dropdown list has a 
value greater than 1 using a regularexpressionvalidator.  I guess I'm not 
sure where this validation should take place.  I would like to validate 
this user control on the parent(if you will) user control.  Is this 
possible?  If so, how would I go about doing it?
