Why don't you create a record group and populate that record group into the list item on runtime?

Add items to a combo box list if not in existing list

I'm trying to set up a combo box for an expense report form. I want users to be able to select an account from an existing combo box list or to add an account to the list if it doesn't exist already.
Ideal situation:
For example, the user has "Office Supplies" and "Meals - Business Related" as existing options in the combo box. They need to enter a parking expense, which doesn't exist on the list, so they type in "Parking" in the combo box. They attempt to advance to the next field. A message box pops up and says, "Do you want to add "Parking" to your list of expense options? They click "Yes" and the combo box will now include Parking in the future.
Any assistance would be greatly appreciated!

George,
Do you know of a way to save the list addition to the original file without saving any new form data with it? In other words, I would like the item to be on the list when the document is opened in the future, but if they just save it, it will save with the form data they've just entered.
Thanks!

Combo box list update or insert restriction

Dear all,
I have a list item which type is combo box.
it shows the Departments list from the department table at run time.
i populate at through a procedure at runtime.
problem
the user could update the list by writing something into it.
i want to force the user to just select a value from the list, not update or insert.
i change the properties of the list item which prevent insertion or updation,
but it disable the selection from the list as well.
how to prevent the user to write something in the combo box list while giving him the
selection authority using the combo box list item?
Thanks and Regards

thank you dear,
but i want to use the combo box instead.
for popup list there is a problem of the null value,
you must assign a value to the popup list and set its required property to true for doing so.
and the combo box do not need this. and my desired functionality require it.

Programmatically Change Combo Box List

Hello,
I searched heavily on these forums and found answers that were close, but I cannot quite figure out the following:
I have a large number of individual RF assemblies, most having the same test requirements. My plan is to create a combo box (or similiar) from which the assembly number can be selected. This box will then provide a numeric value to a case structure, which will then provide the need test parameters and what not.
I know the combo box list can be populated with a property node and the property node fed by an array. It is my hope to be able to put this info in a spreadsheet file that can be updated as necessary and then imported into the VI at run time. Therein lies my problem.
Using the strings and value[ ] property, I can make the combo box work correctly, but I cannot figure out how to import the spreadsheet into the proper format to feed the property node. I've tried various spreadsheet import schemes offered on these forums, but none quite hit it. I've tried to figure it out on my own, but I'm just spinning my wheels.
Any help would be appreciated.
Thanks.

Hello,
I've attached a VI that I think will help you. I actually used the Index & Bundle Cluster Array function, which I don't think I've ever used before. Anyway, this function gets the two arrays of strings from my tab-delimited text file and manipulates them into an array of clusters containing two strings each, which is the data type required by the StringsAndValues[] property of the Combo Box:
I hope this gets you started in the right direction. Good luck!

Regarding input combo box list of values

Hi,
I am using JDev 11.1.1.5.0
I used the input combo box list of values in adf application based on VO.When I type a value in the input combo box and press TAB key,it gives first item of that list rather than that entered value and when I open the list, it shows the repeating values of the first item.
Please suggest me some solutions.

Hi,
hard to say based on your description. Try with 11.1.1.6 or 11.1.17 and if it reproduces, provide a test case based on the HR schema. Is that an option ? Then send it my way in a zip file renamed to "unzip". My mail address is in my OTN profile, just follow the named link left to this reply

How to hide certain items in a Combo Box

I've two Combo Box(CB). First CB contain 4 items(drop-down menus) and the 2nd CB contain 12 items.
I want that when I select one of the items from Combo Box1, then only 4 out of 12 items from Combo Box2 should be visible. So actually I want first combo Box to act as filter. Could this be done using the AS3 code.

I don't think there is any way to hide items, but you can rewrite he items basd on the selectedIndex value of the cbHeight combobox. In the code below, each element of the weightData array is an array of objects.
import fl.data.DataProvider;
var weightData:Array = new Array();
weightData.push([{label: "100"},{label: "110"},{label: "120"},{label: "130"}]);
weightData.push([{label: "200"},{label: "210"},{label: "220"},{label: "230"}]);
weightData.push([{label: "300"},{label: "310"},{label: "320"},{label: "330"}]);
function heightSelected(evt:Event):void
     var hSelected:int = evt.target.selectedIndex;
     var dp:DataProvider = new DataProvider(weightData[hSelected]);
      cbWeight.dataProvider = dp;

Can I use an LOV with a Combo Box?

... and if so, how?
This should be easy, but I've been searching for over an hour now and I keep getting instruction on how to do each individually, but not how to put them together for the desired behavior.
My goal is to have a combo box (single line text field with a drop down arrow) that, when the user clicks the arrow, displays a list populated from a column in the data base and the user selects a value.
I'm using Oracle 10g2
Thanks in advance,
Darren

How to edit items of a combo box that is part of an array of clusters

Hi,
In the attached vi, I have an array of clusters, and each cluster contain two combo boxes. How do I edit the items in Combo Box 1 for all elements of the array? (All Combo Box 1 elements shall include the same items.)
For illustration, I also included the trivila case, i.e., editing the items in a separate combo box that is is not part of an array of clusters (Combo Box 3). Please advise. Thanks.
Peter

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

Using wildcards in combo box list

Is it possible to key in the first letter of a member and retrieve all matches? For example, key in the letter A in the combo box and the drop down list is all of the members starting with the letter A. If so, how?This is for a product dimension that is sorted by sku number. Therefore the aliases are not sorted. Just trying to make it easier to scroll and make a choice.Is another way better? I am trying to use the "AddItem" method.Thanks!

Hi Cletis,You can query the VB API using the EsbOtlQueryMembers function to get member that start with a specified member.. You will do an ESB_WILDSEARCH query type and will specify the string to search for in the pszString1 field of the ESB_PREDICATE_T argument to the function.Alternatively (or additionally), download the free source code for the EssQuery component that we give away on our website (www.appliedolap.com - technology downloads section). You should be able to use this code directly in your Excel code.. Note you may need to change the essbase api declarations to fit your version of Essbase (a pain I know.. This is the reason we created a entire web-service-based API for our ActiveOLAP product and eliminated the need for the Essbase client).Good Luck.. It was good seeing last week at the Nashville User Group meeting.TimTim TowApplied OLAP, Inc

Response to mouse click by combo box list and underlying clickable label

Hello,
we developed a label responding to a mouse click by opening and thereby displaying an associated help text. The label extends a project specific hierarchy of labels and thus implements MouseListener, of course. Now we encountered a strange problem: It occurs when a combo box is placed above such a label in a panel. By clicking the combo box a selective list drops down and covers the label. As soon as a mouse click is performed on a list item directly covering (i.e., right in front of) the clickable label not only this item is selected but the help screen associated with the underlying label is displayed, too. So the mouse click is processed twice: as proposed by the combo box and unwantedly by the label. This behaviour could not be reproduced on other components being placed below a combobox. So the label itself seems to be the cause but we cannot imagine what could exactly be the reason for this double reaction. Perhaps anyone heard of something like that?
We are currently working with IBM Visual Age for Java 2.0 (Java version 1.1.8 with the according Swing version). The clickable label reflectively calls methods of a model to determine whether help is available and if so later on to open this help text.
Any help is appreciated!
Danilo

Thank you for your response. I tried both to check the focus and to consume the event. But I had to learn that labels are not able to catch the focus. I also was not able to consume an appropriate event of the combobox. So I finally solved the problem by extending JButton and implementing ActionListener. Thus my labels are actually buttons but I changed their appearance and behaviour so one cannot distinguish them from labels.

Setting value in input combo box list of values programmatically.

Hi,
I have the following requirement.
I have a combo box LOV defined in the column of application table. Whenever the user is trying to change this value, I need to check for a condition and invoke a warning popup with yes/no button and allow the user to change if dialog outcome is 'yes'. If the outcome is 'No', then i need to reset the combo box to its original value. To do this, in the valuechangelistener of LOV, I am invoking the warning popup and control will coming out of the valuechangelistener and dialog listener will be called.
How do i set the combo box value in dialog listener ? and How do I retain the existing value of the LOV if user clicks on 'No' button.
Jdev Version : Build JDEVADF_11.1.1.7.0_GENERIC_130226.1400.6493
Thanks in advance.
Harish

You could, for example. store both of them (old value, along with new one) in the pageFlowScope. You can do that in the valueChangeListener (before calling popup), and use them in the dialog listener...

Combo box list getting widened while selecting

I have an application , which have combo boxes inside a DIV tag.
When the length of one the item in the list box is greater the specified length of the combo box, the display of the list gets widened and the combo box widens to the lengthiest items' length and it looks odd.
I want the options to fit to the length of the combo box specified.

Could you post a link to a page (actual page or test case) demonstrating the problem?
How are you constraining the width of the <select> control -- have you tried CSS max-width?

Can I disable an item in a combo box list?
