I have the following object:

public var ID : Int;
public var FirstName : String;
public var LastName : String;

And then create Array of these objects...

And then add the array to a DataProvider:

var dp:DataProvider = new DataProvider();
dp.setItems(contactArray);

and then set this data provider as a source for a DropDown:

dropDown.dataProvider = dp;

the problem is the drop down is displayed empty.

How do i tell the drop down which property of the object in the array to use for display and which for ID?

There is a bug in the latest SDK with this issue...perhaps this is what you are experiencing

Thanks but I am not using prompt, therefore based on what is described in that thread this should not apply?

hey p3pp3r,

there is no way to change what field is used when the drop down displays it's text. what i do whenever i have an object, i add a .label property to it. only label properites are used when displaying data in all lists and drop down menus. so just add a label property to your object and set that to what you want to show up on the list. good luck!

JRab - thanks .. but wow..  i will have to add .label property to all my entity objects... and then i may want to display different field in different places.. so this workaround will not take me too far.. This seems to be very basic requirement for any dropdown.. unless i am missing something here...?

I'm using an SQLite database, however I use this to fill the dropdown with information from the database. fishName is a column in the table.

<s:DropDownList id="fishPicker" dataProvider="{fishBarrel}" labelField="fishName" prompt="Choose a Fish"/>

JohnPinkerton,

Many thanks - I see you are using MXML and the MXML control allows you to specify labelField. This is exactly what I am missing in AS3 since my app is entirely written in ActionScript...

I followed JRab's suggestion and ammended some of my objects to have "dynamic" property called .label and included the following in the get method of this property:

public function get label():String
{
	return LastName + ", " + FirstName;
}

but no way to specify it in the DropBox itself...  The DropDown class in ActionScript does not have labelField property...

Ah, gotcha, missed that part. Sorry.
