Mixing client-side and server-side processing: How?

Hi All,
I just picked up an ASP.NET "Mortgage Calculator" example with
code-behind from Prosise's 2002 "Programming Microsoft.NET". Works
great. User enters a few values, clicks button, and monthy payment is
displayed.
When I design apps like this, I like to clear out result fields like
"monthly payment" the minute the user changes any of the parameters of
the mortgage. Doing that server-side looks easy enough, but I'd want
to do it client-side in a real, business app.
So how can I add trapping of onchange events to the asp fields for
client-side processing?
Regards,
RichardThe easiest way would be to generate client-side JavaScript and add it using
the RegisterClientScriptBlock() method and the Attributes.Add() method. I
can't really tell you exactly what the code should look like since I haven't
seen your current code, but if you have ever used JavaScript before it
shouldn't be hard to figure out. Good Luck!
