asp dynamic pulldown menu
Hi, here is what my asp code looks like:
<%
dim conn, strconn, SQL, objrs
SQL = "SELECT * FROM [db] order by id"
SQL2 = "SELECT * FROM [db2] order by id"
SQL3 = "SELECT * FROM [db3] order by id"
strConn= "Driver={Microsoft Access Driver (*.mdb)};DBQ=" & Server.MapPath("../Data/db
set conn = server.createobject("adodb
conn.open strconn
%>
<form method="post" action="stockcosts2.asp" name="form1">
<blockquote>
<p class="style1 style2">Bought:
<select name="bought" class="style2">
<%
set objrs=conn.execute(SQL2)
set objrs2=conn.execute(SQL)
set objrs3=conn.execute(SQL3)
Do While not objRS.EOF
%>
<option value="<%=objrs("bought")%
<%
objRS.MoveNext
loop
%>
</select>
It basically has three pull down menus, and the content within are taken from a database. the table within the database has 4 fields. bought, date, sold, cost. You can view it at www.indavis.com/_private/stockcosts.asp
I was wondering for the first pull down menu "bought", is it possible that for example if I selected ATT, the next two pull down menus will have content that only pertains to records that have ATT? So initially the users chooses the stock in the bought pulldown menu, and once he/she selected a certain stock, ie ATT, the next two pull down menus will have ....Date two options, 1/1/11 and 1/2/03 and Sold two options, DTD, and DTC. Thanks!

cool, i get what you are saying, so pretty much make an iframe/frame and create a javascript that will post to it self which a set of given conditions. Can you show me an example of a javascript that will post to itself once a pull down menu content is selected? Thanks for the fast response!
HELL NO! No frames EVER....heh,heh. I'm adament about no frames!
Yes, you use Javascript to post the page to itself, howerver you don't need frames to do this.
ie.
<%
if request("dropdown1") <> "" then
SQL2 = "SELECT * FROM [db2] where somefield = '" & dropdown1 & "' order by id"
else
SQL2 = "SELECT * FROM [db2] order by id"
end if
%>
<FORM action="" method=POST id=form1 name=form1>
<select name=dropdown1 onchange="javascript:docum
<option value="ATT">ATT</option>
</select>
</form>
etc...

cool, its partially working now. Just a quick question, for example if i select FBB under the pull down menu, once it refreshed and submit the data, the pull down menu still shows the first selection ATT, how do i make it highlight FBB, but still have all the rest under the menu? and also, whats the code to skip duplicate records? IE
<%
set objrs=conn.execute(SQL2)
Do While not objRS.EOF
%>
<option value="<%=objrs("bought")%
<%
objRS.MoveNext
loop
%>
and skip duplicate records? for example just only show one "ATT" and not 3 identical ones?
<%
set objrs=conn.execute(SQL2)
Do While not objRS.EOF
%>
<option value="<%=objrs("bought")%
<%
objRS.MoveNext
loop
%>
and skip duplicate records? for example just only show one "ATT" and not 3 identical ones?
<%
set objrs=conn.execute(SQL2)
Do While not objRS.EOF
if objrs("bought") = request("dropdown1") then
val = " selected"
else
val = ""
end if
%>
<option value="<%=objrs("bought") & val%>"><%=objrs("bought")%
<%
objRS.MoveNext
loop
%>
set objrs=conn.execute(SQL2)
Do While not objRS.EOF
if objrs("bought") = request("dropdown1") then
val = " selected"
else
val = ""
end if
%>
<option value="<%=objrs("bought") & val%>"><%=objrs("bought")%
<%
objRS.MoveNext
loop
%>

thanks for your help!!
btw, how do i skip idential records? IE the pull down menu shows two ATT but i only want it to show one

That's what the code I just gave you does, with minor correction:
<%
set objrs=conn.execute(SQL2)
Do While not objRS.EOF
if objrs("bought") = request("dropdown1") then
val = " selected"
else
val = ""
end if
%>
<option value="<%=objrs("bought")%
<%
objRS.MoveNext
loop
%>
<%
set objrs=conn.execute(SQL2)
Do While not objRS.EOF
if objrs("bought") = request("dropdown1") then
val = " selected"
else
val = ""
end if
%>
<option value="<%=objrs("bought")%
<%
objRS.MoveNext
loop
%>

right, this code selects it correctly, however, the pull down menu still shows multiple duplicate records.
what you are trying is possible !
your SQL2 and SQL3 will have to contain conditions !
for exmaple you defined SQL2 = "SELECT * FROM [db2]"
you will have to define it after the user's selction of the "bought" drop down
then : SQL2 = SQL2 & " Where bought ='" & bought_value_from_dropdown
The you do the same for SQL3.
hope this helps.
