Dynamically populating List box

Hello Everyone:
I need to create a JSP with two combo boxes and submit button.
Where the first combo box will be updated from database - which is simple.
but depending on the selection of the first box the second box should be populated and should be able to make multiple selections in it.
and in the same jsp page should be able to display the results, of what I added by submiting the previous form.
Please can somebody help me witha sample.
Thanks
ASB

There is a selectedIndex property that will give you back the index of the 1st item that is selected.

Populating List Boxes

Azadi – Thanks for your HELP on my last problem.

New?? List Boxes, or drop-down Combo list Boxes, could you or
someone direct me in the proper direction for information on how to
Populate a list box or combo box based on the input of the previous
list box?? Example Enter From Selection - Southern Gulf Coastal
States - All the State in the Southern Gulf Coast would populate
the next combo box, and select a State and all the Coastal Cities
would be of choice and next after cities is the Zip.
I know how to do it in MS Access not sure the best way to
attack this in cf8.
Thanks

There are many ways to do this:
1. By submitting your data to cf server first and query only
according to user selection then populate the target fields
according to query.
2. By querying all data and use javascript
variables/arrays/structures to populate your combo box everytime
user change the selected item.
3. By incorporating Ajax to your CF application.
The first one is the easiest one. But everytime you make
changes to your selection, your app submits to cf server which is
kind of slow 'cause you have to submit everytime selection changes.
The second one is by querying all the data, which is slow at
first 'coz even the unnecessary data are returned. That is, I don't
think the user would try to select all the selections one by one,
but rather maybe just select one item. Though, it will be faster
already when the user selects another item. This way, your form
doesn't have to be re-submitted 'coz you let a javascript
variable/arrays/structures store the data at first query.
The third one(kind of a mix of both 1 and 2), which is the
most efficient way among the three to achieve your goal, needs
learning Ajax which is going to take a few of your time. But if you
know it already, you can let it work well with CF8.
Anyway, a simple sample code for the first method is
attached:

Sir,
The exception is probably in here.
for ( int i = 1; i <= numberOfColumns; i++ ){
results[i] = resultSet.getObject(i);
System.out.print(resultSet.getString(i) + " | " );
}ResultSet counting begins with 1 but array indexing begins with 0 your code should look more like.
for ( int i = 0; i <= numberOfColumns; i++ ){
results[i] = resultSet.getObject(i+1);
System.out.print(resultSet.getString(i+1) + " | " );
}Sincerely,

Hello there,
I am have a similar kind of problem. I am trying to run a video on Pocket PC (WM5) using video.play() method on FlashLite 2.1. It works fine in Device Central and my Nokia mobile (symbian OS with default FlashLite 2.1). Video is obviously embedded in FlashLite 2.1 and was originally in *.3gp format.
Can you please help me where I am going wrong or what am I missing ?

List boxes as filter

Hi,
I’m developing an asp page containing a form with two
dynamically populated list boxes and a submit button. The submit
button should open up another asp page with results filtered by
criteria determined by the contents of the 2 list boxes. I can
populate the list boxes OK but I am not sure about how to use the
selected values as the filter. Can anyone point me in the right
direction?
Thanks,
Chris

Select * WHERE IDFieldName <> Variable1 && / OR
IDFieldName <> Variable2
You can set your variables in the advanced section of your
recordset box.
Check your SQL as the above is just 'pseudo' (I alway shave
to check SQL,
for some reaons can never remember it quite right). The
recordset box will
help you to find the right way to access your variables -
URL/Form/Session,
etc.
HTH,
Jon

How do I enable multiple dynamic drop down boxes?

I'm using Windows 2000, Java SDK 2 Standard, Tomcat, Apache, Microsoft Access and Macromedia Dreamweaver Ultradev 4.
With UltraDev I'm trying to create a jsp page that has more than one dynamic drop down box or more than one dynamic select list box. I can show one dynamic object and as many static objects as I need. But when I add a second dynamic drop down box, with a second recordset, the page will only display the first dynamic object and all content following that object will not display.

Is this a Bug? List Box do not scrollbar: Magic number 2461

In my case I am populating list box from database using script. I noticed strange behavior with List Box being populated more than 2461 list items. At run time List box do not display scrollbar if the list items are more than 2461. Looks like 2461 is the Magic number. I wonder if some one already noticed this behavior. I want to see the scrollbar irrespective of number of list items. In my case I need to load approximately 5000 list items. Any one has suggestions? Is it designed to behave like this or is this a Bug?
Thanks in Advance.
SekharN.

Hi,
I noticed it too !
I have several lists, some oh theme have more than 2460 items and don't have the scroll bar.
An other problem relative to scrollBar in listBox appeared : with Reader 8, i can't use the scroll bar (even if i have less than 2460 items); it appears but i can't scroll.
I see tthe french adobe team about these 2 problems next week. If we find something new, i'll tell you.

Thank u in advance

I'm not sure if the code you display is 'Exactly' how it is written.
If it is:
1) The class needs to be public (i.e. public class ArrayL {.....})
2) In the code below, the value of searchexp is a string
           var searchexp = $("continent").value;
          ArrayL.getNumbers(searchexp, displayItems); but the function
public int[] getNumbers(boolean big) takes a boolean.
3) In the call DWRUtil.addOptions("country", data); 'data' isn't defined did you mean 'items'?
Finally in the statement that you have if (items.length == 0) I have found that does not work with Collections (at least Maps) returned from a method to DWR (as of 1.1.3).
Good luck

Dependent List Boxes

Can't figure what is wrong with this code. Any ideas? My page
is blank unless I remove this code. If I remove the below code the
page shows the form and the list boxes but the last dependent list
box is not functioning properly...

<script language="JavaScript">

</script>

Try something like this:
<span spry:region="dsStates" id="stateSelector">
<select spry:repeatchildren="dsStates" name="stateSelect"
onchange="document.forms[0].citySelect.disabled = true;
dsStates.setCurrentRowNumber(this.selectedIndex);">
<option spry:if="{ds_RowNumber} == {ds_CurrentRowNumber}"
value="{name}" selected="selected">{name}</option>
<option spry:if="{ds_RowNumber} != {ds_CurrentRowNumber}"
value="{name}">{name}</option>
</select>
</span>
City:
<span spry:region="dsCities" id="citySelector">
<select spry:repeatchildren="dsCities" id="citySelect"
name="citySelect" onchange="document.forms[0].schoolSelect.disabled
= true; dsCities.setCurrentRowNumber(this.selectedIndex);">
<option spry:if="{ds_RowNumber} == {ds_CurrentRowNumber}"
value="{name}" selected="selected">{name}</option>
<option spry:if="{ds_RowNumber} != {ds_CurrentRowNumber}"
value="{name}">{name}</option>
</select>
</span>
<span spry:region="dsSchools" id="schoolSelector">
<select spry:repeatchildren="dsSchools" id="schoolSelect"
name="schoolSelect" onchange="window.location=this.value;">
<option spry:if="{ds_RowNumber} == {ds_CurrentRowNumber}"

Populating a Dynamic List Box in CRM Survey

Hi All,
I am currently creating a CRM Survey and am trying to use the 'Dynamic List Box with Single/Multiple Selection' options, but cannot see how i can populate these lists. I get the following error message when selecting the 'Insert Answer Option:
'Dynamic list boxes' cannot contain statistical answer options'
I have tried this through both Survey Suite and UI, but cannot go any further. Can anyone point me to where i can populate this list? Sounds like possible a backend table, but i cannot find which one.
Many Thanks
Indi

Would anyone be able to help please?
Thanks

"Dynamic List Box with Single Selection" Survey Suite in CRM 6.0

Hi
I am using CRM 6.0. There in Survey Suite there are 2 answering options "Dynamic List Box with Single Selection" & "Dynamic List Box with Multiple Selection". I am able to make out, how we can assign values to this. I have seen example "Example_Dynamic_survey" also.
I believe we have to use programming for populating this. But how do we have to carry that out.
Thanx and Regards
Hitesh

Hi Hitesh,
There is no need of programming for populating values for Answer category 'List Box with Single Selection' or 'List Box with Multiple Selection'. You have to follow the following steps to populate values for those:
- In the Answer Category select List Box with Single Selection from drop down list
- Then on left hand side tree, right click on Answer and select Insert Answer Option (Answer->Insert Answer Option)
- Then on right side, provide Text for the answer (value)
- To add more values, repeat the process Answer->Insert Answer Option and providing text for those answers in the right side.
Similarly you can populate values for 'List Box with Multiple Selection' also.
This has to be done in the transaction CRM_SURVEY_SUITE.
Hope this is clear to you
regards
Srikantan

Surveys - dynamic list box option

Hi,
How can I control the entries for the answer category "Dynamic list box with single selection"?
Thanks,
Susana Messias

Hello Susana,
To maintain dynamic values for a specific answer, select your survey in the Survey Suite and go to the maintenance of survey attributes (CTRL+F12). Under the tab 'Technical settings', you can maintain the 'Callback to PBO' function module, which allows you to modify the survey at runtime. (The function module you specify here is called by the survey tool runtime environment at PBO.)
As an example, you can have a look at the function module 'CRM_SVY_EXAMPLE_DYNAMIC_PBO', which contains a section to set answer options at runtime. Of course, you would have to program your own logic to meet your specific requirements for setting the values.
I hope this helps.
Kind regards,
Kristoff

Dynamic retrieval in list boxes using JSP

Dear All,
I have a list box in a form which is created by extracting data from oracle database. There are approximately 26000 records which are added dynamically in the list box. There are five rows in the form and each row has to have a list box with all records. Now if i retrieve all records for all list boxes, the page takes high time to load. I also tried using String array to read once and write them using loops in list box. But even then the loading time is quiet high. Is there some better way so that the page loads fast enough. I am using Oracle Database and the table is indexed.
Thanks & Regards,
Gagan Arora

Well, it's big enough to make any page slow... but you can try to load all the list boxes in the client side with javascript.
i make that usually, create a javascript strings array and on the "onLoad" event fill all the list boxes with the values in that array.
but anyway is too much data.
