Hi guys, i have a question. On old asp, if i did this:

<input type="text" name="myname" value="1">
<input type="text" name="myname" value="2">

asp would make request("myname")="1, 2"

on asp.net, request["myname"] is "1,2" (without the space)

The problem with this is that i am trying to pass multiple currency
values , which have commas inside them. On old asp this wasn't a
problem since i splitted the string with ", " but on asp.net i need to
do "," which of course wouldn't work properly.

Is there a way i can make asp.net use a different separator? Currently
i am employing a hack, replacing the commas with asterisks and then
change then back once read...

I don't know what the advantage of using multiple form elements all with the
same names might be, other than to force you to employ hacks to get around it.
However, the hack you describe seems to work, so "if it ain't broke, don't
fix it".

The advantage is less code.
You can simply split the request variable to an array of strings and
work with them in a simple iteration. If i would use different names
for the variables, it would require more code. Storing objects in the
session or in the viewstate would not be as efficient. Old asp's way
of handling same name input was better IMO

That's not necessarily better...

But less hacking...

Hmm - if you add a new text control between those two, you'd have to give it
a value of 3 - after a while, that would surely get really messy, no...?
