[flexcoders] Re: Generic Function To Set ComboBox Item
What about something along these lines:
private function selectComboItem( cb : ComboBox, item : String, itemField :
String = null ) : int
{
var dp : ICollectionView = cb.dataProvider;
var i : uint = 0;
if ( itemField == null )
itemField = cb.labelField;
for each ( var dpi : Object in dp )
{
if ( dpi[ itemField ] == item )
{
cb.selectedIndex = i;
return i;
}
return -1;
}
Obviously this needs a lot more work to be 100% generic, since the dpi's can be
any kind of object, including primitives like String and XML in the case of
XMLList based data providers, where you will need to use something like (dpi as
XML).attribute( itemField )[0] to get the required item field for comparison.

Try this

Re: [flexcoders] Re: Generic Function To Set ComboBox Item
Actually, the dpID is different for each xmllistcollection being passed.
For example, for an xmllistcollection consisting of Orders, I might have to
need the OrderID, which I am accessing, and it goes on for another
xmllistcollection of States, where on that collection, I might have to access
StatesID.
To give further clarification,
say I have two combo boxes, cmbTeams and cmbCoach. the dataprovider for
cmbTeams is xmllcTeams and for cmbCoach is xmllcCoach.
I want a generic function such that I would be able to set the selectedItem for
each Combo Box instead of writing two.
private function SetComboBoxSelectedItem(itemToSelect:String,
xmlLC:XMLListCollection, cmb:ComboBox, collectionID:String)
Since the collectionID for the xmllcTeams is TeamID, then that is the value
which I pass as collectionID in the function. For the xmllcCoach, it would be
the CoachID.
so what comes now is that when I want to call the function, the collectionID is
represented by the actual ID which to match in the data provider.
For the xmllcTeams
var item:String = xmlLC.getItemAt(i).TeamID
For the xmllcCoach
var item:String = xmlLC.getItemAt(i).CoachID
Generic form>>
var item:String = xmlLC.getItemAt(i).collectionID; ??

Don't you access properties in an XMLListCollection differently than in an
ArrayCollection?
So rather than...
var item:String = dataProv.getItemAt(i).dpID;
it would be
var item:String = dataProv.getItemAt(i)@dpid;
Try doing a debug of your code and see what is being returned also.
