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; ??
Thanks.

Subject: [flexcoders] Re: Generic Function To Set ComboBox Item
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.
