Data Access with ASP+

Not having to code with JavaScript is nice, but at what sacrifice.. Having
to make a trip to the server each time (even if state is auto-maintained as
it is in ASP+)? The applications that I've developed do all the processing
of the server in the background (hidden frame, updates form controls from
that as well) so a web application looks a lot like any other application.

What if I want to do simple validation..Say I want a user to enter a date
that is later than todays date, and not allow them to continue if they do
so. That means now I have to reload (or "blink" as non-tech users call it)
the screen to check that field.

I guess an alternative would be to create my own control that renders client
side java script... But that seems to be defeating the purpose. Bottom
line is to have a quality application you are going to need to do some
client validation, or have some really fat bandwidth so the users don't
notice the reloads. What user wants to wait for a page to reload every time
you fill in something? I think the data grid controls and what not are
excellent for "quick and dirty" database maintanence, but when I want to
write a quality application I need to put some validation in.

Just my thoughts..
