How to change a property of all items of the specific type?

Question

Hello,
this should be fairly simple:
tableA ( id, Flag)
There are 2 pages :
Page 1 : allows user to select P1_ID based on the result set from TableA
Page 2 : there is a bunch of items on this page - text fields, text areas, radio and check boxes, reports etc. There values in those items are based on the following logic :
select <bunch of columns correspond to the page items >
from view1, view2 ...
where <where clause>
and
some_column =:P1_ID
Question:
I need to disallow users to change values in the items of text type on the page 2, if value of P1_ID ( TableA.id) has a value in Flag.
How this can be done ?
The ideal solution would be if i can have a routine that would not require hard coding items names.
Thank you
Andrew

Andrew:
The property that you set is the 'Read Only' property for the page-item. This is done from the 'Edit Page Item' page
The conditions under which this property evaluates to true can be determined dynamically (no hard coding). Take a look at the list of possible Conidtion Types. So, if u want the condition to be table-driven you could choose the 'Exists (SQL query returns at least one row)' and the SQL query could be something like
' select 1 from <you_table> where id=:p1_id '
