here is the copy paste code:
private function findMyVal(cb:ComboBox,n:Number):Number{
for(var i:Number=0;i<cb.dataProvider.length;i++){
if(n == cb.dataProvider[i].id){
return i;
}
}
return 0;
}
and the usage, from the same mxml file: (info: here, me is a custom class )
<mx:ComboBox id="deney" labelField="ad"
dataProvider="{deneyReq.lastResult.dNS.dN}"
selectedIndex="{findMyVal(deney,me.deney_id)}"></mx:ComboBox>
<mx:ComboBox id="user" dataProvider="{userReq.lastResult.uSS.uS}"
labelField="soyadad" selectedIndex="{findMyVal(user,me.user_id)}"></mx:ComboBox>
