Dynamic Drop Downs And Page Variables
i have a website that uses (or needs to use) dynamically driven dropdowns using asp & JS on all pages. it contains 3 different dropdowns that are DB fed and are dependent upon the value of each other. the drop down values are updated using a repost to itself.
they work perfectly on the initial pages where no other variables are involved, but i am having troubles on the pages where more variables are being sent. eg: i have use a lot of error checking, and when i repost, the variables are deleted, and thus the error listings take effect as the variables are now blank. can i refresh the dropdowns without repossting to the samepage without effecting the existing variables on that page? sessions? cookies?

Im getting the functionality of it down first, thats what It looks a little bland. Anyway, the basic idea is that im trying to have a person select a department which brings up a list of class numbers, which brings up a table of tutoring times. Ive just started using ASP a week ago, so don't tear me apart too much. Code:

I've been using ASP for smaller (up to 4 items) dropdown menus, and so far I've been if/then/ statements such as this boolean case:
Code:
<select name=""gift">
" <%If MyGift = true Then %>
<option value="true" selected>YES</option>
<option value="false">NO</option>
<% Else %>
<option value="true">YES</option>
<option value="false" selected>NO</option>
<% End If %>
</select>
How do you set the selected item in a drop-down menu when you have many items in the dropdown, as in the case where the dropdown contains the 31 possible days in a month?

I don't know what to call what I want, but here is the description. Can I use sub-Lists?
I have a dropdown that conatains a list of products. When a user chooses an item, I want another drop down or anything that will allow them to then choose the specific category.
For example:
#1: I have cars and trucks.
When I user selects cars, I want a dropdown to give them available cars to choose from.
Say for instance the user selects Ford. Then I want them to have the option to choose
from the list of Fords. Escort, T-bird etc. Their final choice is what's sent to the DB.
#2: Also, I don't want to give them the option to enter a date into the DB. I have a field in my DB design "timestamp". I want this field to be automatically populated server side once the data is submitted.

i guess it depends on the domain for that answer. If it's a box with hundreds of webpages serving thousands of customers you'd want to conserve network bandwidth you'd probably want to do javascript, but i wouldn't consider reloading a page a big hit since if you just open the connection and runing two queries. But if you need the bandwidth you could do it with javascript.
I try to keep things out of javascripts and out of the hands of the client. Mainly because if they're running an older computer it will take longer to load and put unnessary strain on them and also if the client has scripting disabled you have no more drop down boxes and your site is pretty much disabled. With the strickly asp method you'd have at least the options to choose from and not any core functionality taken from it. That's my 2 cents on javascript to asp.

I have an existing ASP file in a virtual directory. When I type server. or request. in this text file using Microsoft Script Editor I get a dropdown showing the properties available for the object.
However, if I change the extension to ASP on an existing html file, or create a new asp file I'm not getting the dropdown. I suppose this indicates the objects are not available in these new files, and they would not run properly if I tried to open them. What am I missing in setting up these new ASP files?

basically what im trying to do is create a form to submit some data to an access db.
In the form i want to be able to have two dynamically populated drop downs (so if a user chooses cars in the first field it comes up with a bunch of car manufacturers, or if he chooses boats it comes up with boat builders etc etc.)
Ive searched high and low, and i the best i can find is javascript to make the drop dows. The java script however uses a form to repost the data back to the page to populate the second drop down. This wont work when its inside a form.

i have two drop down boxes: student id and student name on a web form.
a database (ms access) has the student id and student name fields in a table.
the drop down boxes should get their values from the table's fields respectively.
i am ok with that (using asp) but my requirement is as follows:
once i select a studentid from textbox1 then automatically the textbox2 should be selected with the corresponding student name.
how can i do this using asp? or can javascript do the job too?

I hope this is the right group. I am very new to ASP so this is
probably a stupid question. I have some vbscript that query's AD and
populates a recordset. I know the recorset contains the information I
want by doing a Response.write. I am having problems dynamically
creating a drop down list from the data in the recordset. The drop down
is created but it is empty. Code:

I need advice how to reduce the size of my drop down list which is created dynamically using a field from my database. If you visit this link you'll see as the box is too long it's knocked out the whole look of the page. Other than shortening the names of the businesses, is there anything else I can do?
My concern is that next year sometime after this site has gone live, it will be maintained with a content manager by people with no IT expertise.

I have an form/application that requires several pages of steps to be completed. On page4 (income school info) I have a dynamic drop down list that builds itself from the database based on member names that the person has entered on the previous pages. When the person filling out the form gets to the end they have the chance to edit their data if something is wrong on page5a.
When they click on the edit icon the member name is passed back to page4 in the querystring. Based on what the member name is in the querystring, I want the dynamically built drop down list to select whatever name is in the querystring. Code:

I have to populate a drop down list from the database depending on the values of another drop down list. And the thing is it should also be able to add more dynamic dropdown lists to it.
Basically is a survey result page for which the one trying to look at the survey has to figure out different criteriaz.
Suppose he's looking for a group of people who are interested in buyin a stuff and then he wants to find if their age is above or below 50 and then further he decides to see if they are employed or not...
I did try a couple of things such as populating a dropdown list in a new page depending on the values passed on by previous one... but was hoping to find a better solution as the one i m workin is tooo complex and tooo complicated.

This will display all records in PropSec table order by SecSort column which has values like '01', '02', '03', '04' and etc.
The reason for this is that i want to sort the records according to the SecSort, '01' first followed by '02' and so on. There musn't be a same value in the drop down box. The no. of records can increase, & not necessary fix to 3 records only.
MS Access db design :
Secsort = text(2)
Title = text(20)
Expected Outcome:
I would want to check to see that the user does not select the same value twice, i.e to prompt out an error message if it does. I am really confused as how to do a dynamic checking when there is no specific field name to check against.
The checking can be done in the secsort.asp or secsort_rs.asp. As long as it can detect the same values & prompt error msg, i am very happy.....

I have a web tool written in ASP. One of the feature is dynamic drop down list which updates a drop down list as another drop down list is changed.I uses javascript to reload the same page to update the drop down list.Everything works fine on the webpage using desktop/laptop.
However, it doesn't work on my mobile device(i.e. one drop down list doesn't get updated as another drop down is changed)how to make it works on mobile device? Should I integrate ASP with another technology,. WAP maybe?

I have a dynamic drop down being populated by a db and then the second drop down is populated depending on what was selected in the first. When it does this though the page refreshes. Is there a way to do this without a page refresh?
I dont think using javascript and arrays is an option cause I am doing this with states and cities and there are about 75,000 records in the db that it is lookin through. Code:

Does anyway know the best way (preferably usinge ASP and avoiding the use of Arrays) how to achieve the following:
I have an ASP page. In it, I have a FORM that contains 2 Radio Buttons and a Drop Down List. I need to have the values of the Drop Down List change depending on which Radio Button is selected by the User.
(I thought that maybe some sort of code acting on the OnChange action for the Radio Buttons might work??).

I have an asp application which I made "Multilanguage". I made an asp file
for every language with all the strings to be used stored like this:
Langstring1 = "French"
Langstring20 = "VTest"
In the beginning of an asp file I determine which language file to include.
In my database there are only numbers. I can now display the right text in
the right language using respons.write: Response.write(Langstring20)
Now I want to use a dropdown box displaying a text as selected based on a
relation between the number in my database and my language files. When I
have number 20 in a database, the value of the option should be 20 and the
text displayed should be 'VTest' for this is Langstring20. Problem is that
the option value seems to be correct with what I do, but the text displayed
in the box is not correct. How can I solve this? Code:

I have a form with 2 drop down menus. the first is populated via a database query and the second gets populated based on the selection made in the first box. (Category/Sub Category)

I am now on the write track for detecting and acting on a variables value. Could someone please have a look over it and see where it is falling out. The help really would be appreciated.
The reason for vTime = vTimex + VTimex1 etc... is because once I get the first part working I will then continue to add up the value until it reaches four. I believe once I get the first part working I can adapt it for the second part. Code:

Is there a way to create dynamic variables when looping through a recordset? For example below, after the 1st loop I'd have myVarA1 and myVarB1, after 2nd loop, I'd get myVarA2 and myVarB2.
CODE ***********************************
set objRS = GetMyRecordSet()
i=1
objRS.MoveFirst
Do While Not objRS.EOF
"myVarA" & i = objRS(0)
"myVarB" & i = objRS(1)
i = i + 1
objRS.MoveNext()

I'd like to create a series of variables created dynamically, example such
as this...
For i = 1 to 5
TheVariable & i = "blah"
Next
This would during the first loop create a variable called 'TheVariable1'
with a value of 'blah'. Is this possible as so far I'm getting syntax
errors?

What's the correct syntax here:
(given the recordset myRS with x records
do until myRS.EOF
txtvar & myRS("serial_number") = myRS("serial_name")
myRS.movenext
loop
..asp will not build the dynamic variables
txtvar1 = "Some name"
txtvar2 = "Any name"
txtvar3 = "Your name"
.....
Based on the serial_number in the current recordset.How can I builde the dynamic variables, and give them a value from my recordset?

I have a spare parts database that I am working on. All that needs to be stored is the part description, what it goes to, and the quantity in stock.
Since that's all that I need, I want to be able to allow the user to edit the quantity right on the results page, through a textbox. Just change the number in the textbox for each part, press the button, and voila, it's all saved to the database (and is redisplayed for your convenience.)
However, there is no set amount of part rows. Right now, I'm creating the text boxes using the id of the item (i.e., name="quantity<%=RS("partID")%>"), but I'm not certain how to call the variables to put in an insert.
What is the syntax for dynamic/variable variables (if they even exist in ASP)?

I had successfully created a update page for a registration. But now I went into a problem.
1: In REGISTRATION page (Where they submit their data for the first time), they are able to use Drop down button to choose their answers. In my UPDATE page (Where they can edit their data), I can only create textbox for them to change their data which they originally used Drop down button.
For example: In REGISTRATION page, they can choose Yes/No from Drop Down button. In UPDATE page, they need to type in Yes/No instead from Drop Down button.
How can I create drop down button in the update page with their previous answer selected?
