Subject: [flexcoders] Adding Item to a ComboBox
I currently successfully webservice in a list of schools which I place
in a Combobox
The key code being
a)<mx:operation name="getCities">
b)<mx:ArrayCollection id="cities"
source="{mx.utils.ArrayUtil.toArray(ContactService.getCities.result)}"
/>
c)<mx:ComboBox id="cities_cb" dataProvider="{cities}"
labelField="CITY" width="150"></mx:ComboBox>
I want to be able to add extra items e.g "All Cities"
I have tried to follow the livedocs example
http://livedocs.macromedia.com/labs/1/flex/wwhelp/wwhimpl/js/html/wwhelp
.htm?href=00000531.html
updating an array using the IList interface
but am getting multiple errors when I try adding a function to
do addItemAt
a)<mx:operation name="getCities"
result="citiesResultHandler(event.result)">
b)public function citiesResultHandler(result:Object) {
public var myIList:IList = new
ArrayCollection({mx.utils.ArrayUtil.toArray(ContactService.getCities.res
ult)});
// The function to change the collection, and therefore the
Array.
myIList.addItemAt("All Cities", 0);
}
c) <mx:ComboBox id="cities_cb" dataProvider="{myIList}"
labelField="CITY" width="150"></mx:ComboBox>
Obviously I am using the wrong terminology in the function
