I'm dynamically creating an IList to use as a dataprovider for a DropDownList in Flex.
The code is creating the IList correctly, and I can access the data inside just fine.
However, when I set the dataprovider for my DropDownList, it only shows blank entries for each item in the list.[code]...
I need to display DropDownLists in a column of a DataGrid in my Flex application. Here is what I am doing:
First, I have a item renderer function that creates a custom item renderer, and passes it a property that is an IList that will be used as the dataProvider of the dropDownList:
private function rendererFunction(item:Object):ClassFactory {
var itemRenderer:ClassFactory = new ClassFactory(AudActionDropDownIR);
itemRenderer.properties = {AudActionData: AudActionData};
[Code]....
First, how can I call the init function when the renderer is created? Second, when I set the column's itemRendererFunction="rendererFunction", the app will not launch, a white screen comes up. But when I set itemRenderer="components.AudActionDropDownIR", the app will launch, but of course there is no data in the dropdown list.
I have two dataProvider's for one DropDownList. The following code can be compiled and run.
<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"

How to turn Array (like Camera.names) into IList (for for ex MXML s:DropDownList
<s:DropDownList x="113" y="121" selectedIndex="0" dataProvider="{Camera.names}"></s:DropDownList>
)?
[code]....
I'm using Flex 3.3, with hamcrest-as3 used to test for item membership in a list as part of my unit tests:
var myList: IList = new ArrayCollection(['a', 'b', 'c']).list;
assertThat(myList, hasItems('a', 'b', 'c'));
The problem is that apparently the IList class doesn't support for each iteration; for example, with the above list, this will not trace anything:
for each (var i: * in myList) { trace (i); }
However, tracing either an Array or an ArrayCollection containing the same data will work just fine.What I want to do is (without having to tear apart my existing IList-based interface) be able to treat an IList like an Array or an ArrayCollection for the purposes of testing, because that's what hamcrest does:
override public function matches(collection:Object):Boolean
{
for each (var item:Object in collection)
{

I am acquiring the contents of a table to fill a dropdown box in a Flex 3 application:
<mx:ComboBox dataSource="{myList}" />
The list is populated by the contents of a database table of persons:
Public, John Q
Doe, Jane
...
The combo box, however, also needs to have some other meta-entries in it that do not come from the database:
ALL
ALL MEN
ALL WOMEN
Public, John Q
Doe, Jane
...
I am deploying a desktop application using AIR, and I would like to store some user-specific data on the machine such as a history of his entries.

View 1 RepliesI'm having difficulty figuring out how to add a dropdownlist control to only a single row of a data grid. For example, if I have two rows of data in the grid, I want the top to be the normal text from the data provider, and the second row to be a dropdownlist (bound to an array collection).
View 1 RepliesI'm sure this is a easy one but I've been searching for a while how to select a DropDownList element with actionscript. In this scenario, I'd like to be able to specify the selectedItem based either on ddlLabel or ddlData

I am making some simple project and I have problem with selectedItem. I have sth like this
<s:State name="Form" enterState="makesService.send()"/>
so when I enter this state I take makes from database and populate them to dropdownlist.
but I have also button and on click event I'm changing state to this Form and I want to select specific make from the dropdownlist but I can't. I'm not sure whether I'm doing sth wrong or the problem is that I'm selecting item just before the dropdownlist became populated.
e.x. List of make consist of Audi and BMW and when I click button I want to open this state Form in which this dropdownlist exist with selected value e.x. BMW.
I have created a custom ComboCheck which extends the spark DropDownList that is a DropDownList of checkboxes. Inside of my itemRenderer I have the code:
[Bindable]override public function set data (value:Object):void {
if (value!=null) {
_data = value;
[Code].....
This will also not cause the dropdownlist to reset to scrollPosition 0
I have a XML structure like:
<Main>
<Category1>
<Data Name="Data1">

I want to adjust the width of DropDownList control in flex 4. I could do it by editing the skinclass and setting the PopupAnchor's Property "popUpWidthMatchesAnchorWidth" to false, but in my application I have to do it using actionscript.

I have just implemented a dropdownlist of checkboxes taken from this ComboCheck example but made it extend DropDownList instead of ComboBox to provide better functionality that I required. I am attempting to create a DropDownList where some items are bold and non-checkboxes (or can be checkboxes) and others are not.
I have not been able to find anything online about doing this yet and have been trying to figure it out. I am currently using an ArrayCollection as a dataProvider but I think this could possibly be my issue and I should be trying to setup the labels in flex not AS3.[code]...
Using FB4, I want to change the height of an open spark DropDownList. By default, it shows up to 6 items before scrolling. My dropdownlist contains 7 items, so I want to change the height of the open dropdown list to fit all 7 items without scrolling. As a workaround, I've changed the font size of the items so that they are smaller and all 7 fit, but the smaller font doesn't look good. Is there a way to change this height?
View 5 RepliesI have a Flex Spark dropdownList in which I need to show the Provider FirstName,LastName:
<s:DropDownList id="providerList"
dataProvider="{model.practiceProviderList.practiceProviders}"
labelField="provider.providerName.firstName"/>
But the output shows only [object Object] & [object Object] as there are 2 providers in the DB and does not show the actual values.
The PracticeProviderList.as:
[Bindable]
[RemoteClass(alias="model.PracticeProviderList")]
public class PracticeProviderList extends PracticeProviderListBase {
[Code]....
The Provider has providerName:PersonName as one of it's fields & PersonName has firstName:String & lastName:String
I'm fetching some data from a PHP application using Zend AMF. However I can't get the data to bind to a simple DropDownList control. The PHP method is:

In this code I'm creating a new window when I click the button. In the new window are TextInput and DropDownList components. When the new window opens, clicking the DropDownList does nothing - you have to click it a second time round to get it to open. However, click into the TextInput field first and then try opening the DropDownList works no problem.
Below is the code, or download the FXP file here.

I'm trying to use the Spark DropDownList as itemEditor in an AdvancedDataGrid. Howerver, I've stumbled onto two issues:Clicking on a item in the DropDownList changes the selected row in the ADG. You can see this behavior by compiling the code from below and executing the following steps.The value changes from "A" to "C" and Row 3 is the selected row in the ADG. It looks like the mouse click in the DropDownList is also handled by the ADG itself which changes the selected row accordingly. I couldn't figure out a way to prevent this. The expected behavior would be that row 1 is still selected after the DropDownList has been closed.Clicking on the scrollbar of the DropDownList closes the DropDownList. (I just found the solution to this problem in the relatated questions while writing this: Scrollbars in dropdownlist inside DataGrid itemEditor not working)

I have an AIR application with 2-3 DropDownLists and a bunch of other controls. The DropDownLists are bound to dataproviders (ArrayCollections) in a central Model singleton. On launch, they all work fine.
However, when I click a button to add new objects to an object in another ArrayCollection in the same Model, the DropDownLists get weird. They still register clicks, and all other controls still work as before, but the dropdowns won't open. Clicking/waiting enough usually opens the dropdown, but if I don't make another selection it still won't open after closing. Making a different selection makes that DropDownList work again, but the others might still refuse to open.
If I open the dropdowns using Ctrl + Down arrow, they work all the time, so it's only the click that doesn't trigger the open correctly. I can work around the problem by calling openDropDown() on the dropdown when clicked, but that doesn't feel right.
I'm using the 4.1 SDK, and the dropdowns are s:DropDownLists. I tried using mx:ComboBoxes instead, but got the same behavior. Edit: Weirdly enough, using s:ComboBoxes they work as they should, but I really don't want to use them since they seemingly can't be made non-editable.
I am using FlashBuilder 4.5 for PHP. I have a simple MySQL table with the fields {tID, tName}.I am able to populate a DropDownList in a Flex form as below. The DropDownList shows the name of the people without problem:
<s:Form defaultButton="{button}">
<s:FormItem label="myList: ">
<s:DropDownList id="dropDownList" creationComplete="dropDownList_creationCompleteHandler(event)" >
<s:AsyncListView list="{getPeopleResult.lastResult}"/>
[code]....
The above does not work.
I'd to use my database field value to select a value on my <s:DropDownList. I try to do
<s:DropDownList dataProvider="{DP_PAT_CIVIL}" selectedItem="@{objectUser.usrQualParent}"/>
But no selection appear, nothing appear on prompt.
objectUser.usrQualParent represent a value with is present in the dataprovider DP_PAT_CIVIL. For exemple, dataprovider is:
[Bindable]
private var DP_PAT_CIVIL:ArrayCollection = new ArrayCollection (
[{label:"Monsieur" , data:"0"},[code].....
This is what I've done so far.
<!-- fill -->
<!--- Defines the appearance of drop-down list's background fill. -->
<s:Rect id="background" left="1" right="1" top="1" bottom="1" >
<s:fill>
[Code].....
If you look closely you'll see that I've changed the default value for the bgFill color. However, when I run my application, the background color for the dropdownlist is still the default white.
I make the datagrid editable so that the selection can be passed from renderer to datagrid the scroll bars in the dropDownList fail to work. What can be done, nobody seems to know. If you know please let everyone know.[code]

When using a dropdownlist in flex I'd like to know the exact index value when the prompt is initialized in it.
View 1 RepliesI want to extend DropDownList control to include an option for creating or editing the options. For example; for a list of projects in the dropdown list, there will be another option that says "Create new project..." or "Edit projects..." and this will be the last option in the list. When user selects this option, the selectedIndex or selectedItem will not change and corresponding action will be taken (for example a popup window shows up).This will be a convenient way for the end user. Now I want this to work independent of the context and the class must be reusable. User will only specify the optionText and optionFunction to work this out. The basic structure of the class looks like this:
public class OptiveDropDownList extends DropDownList
{
private var _enableOption:Boolean;
