Help needed on combo-box dynamic values??

Hi ,
i need to populate values in 2 combo-boxes where the values
in the second combo is dependent on the first .. from db ...
i.e if i select a value in 1 combo then the values in the second combo should be populated accordingly from the db..
pls suggest on this.

You can use onchange event of the first combo box, then you can submit a form sending the first combo box value, then response filling the second combo box.
If you don't want to make a request, you should use ajax to get data from database.

Need Help, retrieving a combo boxes actual/print/visible value instead of the export value.

Hello,
I need help, retrieving a combo boxes actual value, not the export value.
I have a combo box with multiple options to select from.
each of those selections has a separate export value, which is in the form of a number, which I use to calculate dates in a separate field.
However, I have another field that i want to retrieve the, users selected value, which is text, from the combo box instead of the export value.
Is there an easy way to do this.
This is what I am currently using. But like I said the results are that I retrieve the export value and not the selected text value.
event.value = this.getField("_Arugula").valueAsString;
Thanks

First get the currentValueIndices property of the combo box and use it with the getItemAt field method to return (what I call) the display value. Something like:
var f = getField("combo1");
var display_value = f.getItemAt(f.currentValueIndices, false);
See the documentation for more information

I need a combo box with 4 values to choose from which will populate a text box on the form with text related to each combo box selection

For example:
Combo box choices:
apple
tomato
squash
Pumpkin
The text box depending on the selection above would state the color:
Green        (if Apple was chosen from the combo box
Red           (if Tomato was chosen from the combo box
Yellow       (if Squash was chosen from the combo box
Orange      (if Pumpkin was chosen from the combo box
I am very new at this and have spent hours looking for an answer. Thank to anyone in advance who can help!

Place each value as the export value of the options in the combo-box and then use this code as the text field's custom calculation script:
event.value = this.getField("ComboBox Name").value;

Combo Box Valid Values Update

Hi All,
I'm developing a Form which has BP Code and a ComboBox which, after entering a valid Supplier in the BPCode EditText, updates the ComboBox with the Supplier Catalog Numbers of all the Items where the CardCode (in OITM) matches the BPCode. I have this working for the first change of BPCode but when the BPCode changes I want to update the ComboBox ValidValues. I have tried many methods but cannot remove the ValidValues which are already there. I have tried linking the ComboBox to a DataTable, clearing the DataTable and rebinding but this doesn't seem to work either.
Any help on removing ValidValues from a list when I don't know what is already there (as the VV list is now out of scope) or adding a data bound ComboBox would be most appreciated.
Thanks in anticipation,
David

Hi David,
Try following
        'get the reference to the state combo box
        oCombo = oForm.Items.Item("combo box unique id").Specific
        'remove existing items if any
        'before adding new items
        For Flag = 0 To oCombo.ValidValues.Count - 1
            oCombo.ValidValues.Remove(0, SAPbouiCOM.BoSearchKey.psk_Index)
        Next
After this, use a recordset or datatable to retrieve the records, and than a loop to add valid values to the combo box.

Populating a combo box using values in a table

I am trying to populate a drop down box with values from a table. I have got so far.
The combo box is populated however the values in the box are blank.
Can some suggest the necessary modifications?
$query="select distinct(house_type) from tbl_accommodation";
$stmt = ociparse($conn, $query);
ociexecute($stmt);
echo '<select name="house_type">';
echo '<option value = "-1">Select:</option>';
while($row=ocifetch($stmt)) {
echo '<option>' . $row['house_type'] . '</option>';
echo '</select>';
Thanks

The ocifetch() function needs ociresult() to get the data. See
http://us.php.net/manual/en/function.oci-result.php
You might want to use oci_fetch_assoc() instead.
while($row=oci_fetch_assoc($stmt)) {
echo '<option>' . $row['HOUSE_TYPE'] . '</option>';
}For associative arrays, use the column name in upper case.
NB Oci_fetch_assoc() is a PHP 5 function. If you don't have it, then
you are using PHP 4 which has a much older version of the OCI8
extension. I'd recommend upgrading PHP, or just replacing the old
OCI8 with a newer one. See other recent threads about how to do this.

Help with linking combo boxes so that some options are made unavailable

Hello!
I'm having trouble setting up an interactive PDF form with multiple combo boxes.
I have designed an interactive PDF form in InDesign CS6 but am doing the final preparation and formatting in Adobe Acrobat XI Pro.
First of all, I am not sure if I should be using combo boxes or list boxes, but the combo box seemd to look better after I export the PDF and also left the field blank, ready for selection from the drop-down menu.
Basically I have a list of drop-down lists, but not all combinations are compatible. For example, after maing "Selection 1" in "Combo box 1", I need only "Selection 1", "2", and "3" [out of the total 5] to be available in "Combo box 2".
I need to be able to apply this algorhythm to the next few combo boxes as well.
Moreover, I would need some of the checkboxes disabled [the user won't be able to check them at all]when I make a certain selection in some of the combo boxes.
Needless to say, I don't know any Java, coding or making calculations in LiveCycle Designer, so I don't even know where to begin.
I have attached a screen grab of my form and what I want to achieve.
Any help would be very much appreciated.
Thank you!

If it is static data, I would suggest you to cache it rather than having it in each of the user session. You can have configuration/code to refresh when needed. Please look at any available caching frameworks (EhCache, OSCache etc...)

Combo box displays value instead of label

I have several combo boxes on a vi that will occasionally start displaying the value of an certain items instead of the string label when an element is selected. The only way to fix it is to deleted the combo box and replace it with another. This has happened several times on the same vi. Sometimes it is ok when the vi is run in the IDE but shows up in an executable. Is this a bug?
Thanks,
Bill F

I think this is to be expected. Your control will have a value with no associated text.
It would be much more dangerous if LabVIEW would randomly change (e.g. coerce) the value when the strings array gets shorter by some mechanism.
You have several possibilities, for example:
(1) Check the value and coerce to the highest valid entry or switch to entry zero.
(2) Keep the array of strings at constant size, but replace the unwanted entries with empty strings (see attached), the string "out of range", "invalid selection", or similar.
LabVIEW Champion . Do more with less code and in less time .

Combo Box - List Value Property

I have a combo box in a form (Forms 10G) which is populated at runtime using values from a parameter table.But when I generate the form it gives a warning message that the list item property has to be filled .
The combo box should display only the values from the database but it should not have any default values.
How can I supress the warning message and avoid entering the list values proeprty at design time.
Thanks in Advance.

The warning is part of forms functionality, but is just that, a Warning, and the form should compile if not an error exists. Not sure if there's a way to suppress it, and You can simply leave the list with no values in Your design, as You will provide them at runtime. If coding is ok Your list should display the values You extract from the DB

Load data in a combo box dynamically

Someone could guide whether this is possible, and if you have any examples that would be great.
greetings

Help needed urgently to get the values from the jsp page.

hi,
I am badly stuck into this problem.Please help me and find a solution.
I am using ms-access and jsp.
my database structure is as given below:
m_emp_no | from_date | to_date | approver| status |
1002 | 22/9/2008 | 23/9/2008|1003 |pending
1004 | 29/9/2008 | 30/9/2008|1003 |pending
2044 | 15/9/2008 | 16/9/2008|3076 |pending
now this is exactly a leave apply scenario where a page is displayed and the user has to fill in the details to apply leave.then the approver has to approve that leaves so even, he should get the details in his account.
for example here 1003 has to approve leaves for 1002 & 1004.i am able to fetch data from database for the particular approver here is the coding:

    </tr>

</html>{code}
this will display both the rows but when i try to retrieve the values into update.jsp using the code given below it gives me only one value which is the first 1002.
{code}approved=(String)request.getParameter("approved");
id=(String)request.getParameter("id");{code}
but i need both the values to be inserted into the update.jsp only then the approver will be able to approve the leaves individually with respect to the m_emp_no.
please help me out.
thanks in advance.

However, when the same attributes are printed out in the itemSearch method, the values are all null!!! There is nothing that happens in between the two methods and i am completely baffled as to why it does this. It worked fine before i recently changed the input method of the type to JComboBox instead of text field and i had no problems passing through the values.
If anyone could help me out with this it would be great!
Thank you!
Edited by: Chrift on May 24, 2009 10:01 AM

Ah thank you, so by having the word String in front of the variable names when declaring them i was overriding them and therefore making them local variables.
I think this is correct, i havent time to test it at the moment so i will declare this question answered when i do!
Thank you very much :D
