Automatic form field update based on previous form value selection

[Brett_A]

I have a form where the first field is a dynamic drop-down that pulls
from a db (Access). The fields associated with the query are task_id,
task_name and task_rate. The field has the value of "task_id" and the
label of "task_name".

In the second form field, I would like the default value to be
determined by the selection made in the first field. Based on the
selection of the first form field, I would like the default value of
the this field (task_rate) to be populated with the associated
task_rate value of the selection chosen above.

Any suggestions?

Thanks

Brett

If this is a serverside code problem, show your code,
if it is clientside code or a html Q, ask elsewhere.

Are for frik'n real Evertjan?

This is an ASP forum, I'm asking an ASP question.

I don't have the code because I need some direction on how to write
the code. Did you read my question? Do you understand my question?
Did I say I already have code that isn't working?

I explain what I want and ask for suggestions. If my question isn't
clear, than I need to fix it.

Thanks

This is typically done in client-side code so it is more appropriately
asked in a client-side scripting group such as
microsoft.public.scripting.jscript
However, you can look here to get a head start and narrow your question
down to more specific issues:
http://classicasp.aspfaq.com/forms/how-do-i-make-one-dropdown-depend-on-another.html

While the client-side scripting is the major part of the solution, there
may be server-side asp issues as well that we will be happy to address
here.

Getting angry usually shows getting angry at yourself.
Don't, it does not help you.

This is an ASP forum, I'm asking an ASP question.

How can we be sure, Bret?
Many a time Qs are asked in the wrong NG.
Your Q does not specify it as such.

I don't have the code because I need some direction on how to write
the code.
So?

Did you read my question?
Yes

Do you understand my question?

Not completely, it seems not directed at a serverside problem.
Could you specify the serverside Q?
It seeme you want dynamically changing formfields content.

Did I say I already have code that isn't working?

Should you?

Yes you should.
This NG usually helps people that get stuck,
but usually does not write code for others out of the blue.

I explain what I want and ask for suggestions. If my question isn't
clear, than I need to fix it.

Help yourself.

Seems very clientside to me!
Classic ASP does not know of forms
nor of dynamically changing formfields.

This is what you answered:

If you read my question, why would you ask if I had a code problem? I
hadn't gotten that fair in the development. After reading the other
answers and doing more research, it is partially client-side issue - I
think I need some AJAX to create the desired functionality. I was
asking the initial question to see where I should start - the last
sentence was "Any suggestions"? If you thought it was a client side
issue, why not answer like Bob did? It was informative without being
condescending.

The first form field is a dynamically populated list. The second form
field is a text box, not another list. The value to populate the
second text box is a value that needs to be pulled from the database
determined by the value of the selected value from the first form
field. I don't want a page refresh which is what seems to happen if I
set it up as outlined in the samples suggested.Something has to happen
on the server side to retrieve that value before any onchange event
can update the second field with the proper value doesn't it? Is this
a place where I need to implement some AJAX?

Thanks

[wrong quoting level]

Because that is the main subject of this NG,
and you did not include such problem.

I hadn't gotten that fair in the development.

Ah, so you were just fishing? "that fair"? I think not sofar.

After reading the other
answers and doing more research, it is partially client-side issue - I
think I need some AJAX to create the desired functionality.

Indeed. Ajax is in fact clientside coding technology,
as the requested html streamlayout from the server could be,
but not necessarily has to be,
prepared by serverside coding,
which coding even then is not part of AJAX technology as such.

I was
asking the initial question to see where I should start - the last
sentence was "Any suggestions"? If you thought it was a client side
issue, why not answer like Bob did? It was informative without being
condescending.

So that is the bottom line:
You are asking and at the same time think
you have a right to determine how the response should be?

While it was not my intention to be condescending,
[you could be from the west side of the great pond,
where such sensitivities excessively abound,
as seen from the rest of cyberworld,]
it won't do to expect the absence of condescence on usenet.

"Any suggestions"?

So again, show us the serverside problem, and do some initial work
yourself, and you have a good chance of getting help where you get stuck.

Right. it sounds as if you know how to accomplish the server-side aspect of
this problem.

Is this
a place where I need to implement some AJAX?

If you don't want to submit the form to get the new value, then yes, AJAX,
or something like that will be required. The client-side scripting group is
the place to get help with that.
