I would like to know what is the best way to validate input parameters:
a) Custom code.
b) Through Stored Procedure .
c) An expressión with conditional to show or hide an object.
Besides that, I created a regular expression to check if a text is entered properly. If the condition evaluates to "No", the report is not shown and a mesage appears. When the conditions evaluates to "Yes", the report is shown. The condition was included in a expression of a text box, and it´s evaluated when a press on View Report. I´d like to know if the Stored Procedure with the business logic is run despite the iff condition is evaluated to "no".
Thanks,

Ramiro.
