Starting with Flex 4.0, Apache recommends that you use the spark.components.DropDownList class as an alternative to this class. |
The ComboBox control has the following default sizing characteristics:
Characteristic | Description |
---|---|
Default size | Wide enough to accommodate the longest entry in the
drop-down list in the display area of the main
control, plus the drop-down button. When the
drop-down list is not visible, the default height
is based on the label text size.
The default drop-down list height is five rows, or the number of entries in the drop-down list, whichever is smaller. The default height of each entry in the drop-down list is 22 pixels. |
Minimum size | 0 pixels. |
Maximum size | 5000 by 5000. |
dropdownWidth | The width of the ComboBox control. |
rowCount | 5 rows. |
The <mx:ComboBox>
tag inherits all the tag attributes
of its superclass, and adds the following tag attributes:

data | property |
data:Object
Language Version : | ActionScript 3.0 |
Product Version : | Flex 3 |
Runtime Versions : | Flash Player 9, AIR 1.1 |
The data
property lets you pass a value
to the component when you use it in an item renderer or item editor.
You typically use data binding to bind a field of the data
property to a property of this component.
The ComboBox control uses the listData
property and the
data
property as follows. If the ComboBox is in a
DataGrid control, it expects the dataField
property of the
column to map to a property in the data and sets
selectedItem
to that property. If the ComboBox control is
in a List control, it expects the labelField
of the list
to map to a property in the data and sets selectedItem
to
that property.
Otherwise, it sets selectedItem
to the data itself.
You do not set this property in MXML.
This property can be used as the source for data binding.
public function get data():Object
public function set data(value:Object):void

dataProvider | property |
dataProvider:Object
[override] Language Version : | ActionScript 3.0 |
Product Version : | Flex 3 |
Runtime Versions : | Flash Player 9, AIR 1.1 |
The set of items this component displays. This property is of type Object because the derived classes can handle a variety of data types such as Arrays, XML, ICollectionViews, and other classes. All are converted into an ICollectionView and that ICollectionView is returned if you get the value of this property; you will not get the value you set if it was not an ICollectionView.
Setting this property will adjust the selectedIndex
property (and therefore the selectedItem
property) if
the selectedIndex
property has not otherwise been set.
If there is no prompt
property, the selectedIndex
property will be set to 0; otherwise it will remain at -1,
the index used for the prompt string.
If the selectedIndex
property has been set and
it is out of range of the new data provider, unexpected behavior is
likely to occur.
This property can be used as the source for data binding.

dropdownWidth | property |
dropdownWidth:Number
Language Version : | ActionScript 3.0 |
Product Version : | Flex 3 |
Runtime Versions : | Flash Player 9, AIR 1.1 |
Width of the drop-down list, in pixels.
The default value is 100 or the width of the longest text
in the dataProvider
, whichever is greater.
This property can be used as the source for data binding.
public function get dropdownWidth():Number
public function set dropdownWidth(value:Number):void
itemRenderer | property |
itemRenderer:IFactory
Language Version : | ActionScript 3.0 |
Product Version : | Flex 3 |
Runtime Versions : | Flash Player 9, AIR 1.1 |
IFactory that generates the instances that displays the data for the drop-down list of the control. You can use this property to specify a custom item renderer for the drop-down list.
The control uses a List control internally to create the drop-down list. The default item renderer for the List control is the ListItemRenderer class, which draws the text associated with each item in the list, and an optional icon.
public function get itemRenderer():IFactory
public function set itemRenderer(value:IFactory):void

labelField | property |
labelField:String
Language Version : | ActionScript 3.0 |
Product Version : | Flex 3 |
Runtime Versions : | Flash Player 9, AIR 1.1 |
Name of the field in the items in the dataProvider
Array to display as the label in the TextInput portion and drop-down list.
By default, the control uses a property named label
on each Array object and displays it.
However, if the dataProvider
items do not contain
a label
property, you can set the labelField
property to use a different property.
This property can be used as the source for data binding.
public function get labelField():String
public function set labelField(value:String):void
labelFunction | property |
labelFunction:Function
Language Version : | ActionScript 3.0 |
Product Version : | Flex 3 |
Runtime Versions : | Flash Player 9, AIR 1.1 |
User-supplied function to run on each item to determine its label.
By default the control uses a property named label
on each dataProvider
item to determine its label.
However, some data sets do not have a label
property,
or do not have another property that can be used for displaying
as a label.
An example is a data set that has lastName
and
firstName
fields but you want to display full names.
You use labelFunction
to specify a callback function
that uses the appropriate fields and return a displayable String.
The labelFunction takes a single argument which is the item in the dataProvider and returns a String:
myLabelFunction(item:Object):String
This property can be used as the source for data binding.
public function get labelFunction():Function
public function set labelFunction(value:Function):void
listData | property |
listData:BaseListData
Language Version : | ActionScript 3.0 |
Product Version : | Flex 3 |
Runtime Versions : | Flash Player 9, AIR 1.1 |
When a component is used as a drop-in item renderer or drop-in item
editor, Flex initializes the listData
property of the
component with the appropriate data from the List control. The
component can then use the listData
property and the
data
property to display the appropriate information
as a drop-in item renderer or drop-in item editor.
You do not set this property in MXML or ActionScript; Flex sets it when the component is used as a drop-in item renderer or drop-in item editor.
This property can be used as the source for data binding.

prompt | property |
prompt:String
Language Version : | ActionScript 3.0 |
Product Version : | Flex 3 |
Runtime Versions : | Flash Player 9, AIR 1.1 |
The prompt for the ComboBox control. A prompt is
a String that is displayed in the TextInput portion of the
ComboBox when selectedIndex
= -1. It is usually
a String like "Select one...". If there is no
prompt, the ComboBox control sets selectedIndex
to 0
and displays the first item in the dataProvider
.
public function get prompt():String
public function set prompt(value:String):void
rowCount | property |
rowCount:int
Language Version : | ActionScript 3.0 |

The default value is 5
.
This property can be used as the source for data binding.
public function get rowCount():int
public function set rowCount(value:int):void
selectedIndex | property |
selectedIndex:int
[override] Language Version : | ActionScript 3.0 |
Product Version : | Flex 3 |
Runtime Versions : | Flash Player 9, AIR 1.1 |
Index of the selected item in the drop-down list. Setting this property sets the current index and displays the associated label in the TextInput portion.
The default value is -1, but it set to 0
when a dataProvider
is assigned, unless there is a prompt.
If the control is editable, and the user types in the TextInput portion,
the value of the selectedIndex
property becomes
-1. If the value of the selectedIndex
property is out of range, the selectedIndex
property is set to the last
item in the dataProvider
.
This property can be used as the source for data binding.
public function get selectedIndex():int
public function set selectedIndex(value:int):void
selectedItem | property |
selectedItem:Object
[override] Language Version : | ActionScript 3.0 |
Product Version : | Flex 3 |
Runtime Versions : | Flash Player 9, AIR 1.1 |
Contains a reference to the selected item in the
dataProvider
.
If the data is an object or class instance, modifying
properties in the object or instance modifies the dataProvider
and thus its views. Setting the selectedItem itself causes the
ComboBox to select that item (display it in the TextInput portion and set
the selectedIndex) if it exists in the dataProvider.
If the ComboBox control is editable, the selectedItem
property is null
if the user types any text
into the TextInput.
It has a value only if the user selects an item from the drop-down
list, or if it is set programmatically.
This property can be used as the source for data binding.
