okay this is exactly what am doing. i have an arraycollection(dataAr) that is
populated by data from a database. i have a multiple filter function that i use
to filter the arraycollection(dataAr) and each time its filtered i refresh it.
i then assign the filtered arraycollection(dataAr) to a new
arraycollection(copydataAr), which i use as the dataprovider for the tilelist.
here is a snippet of the code.
[Bindable]
private var dataAr:ArrayCollection = new ArrayCollection;
public function displayResult(event:ResultEvent):void{
dataAr = new ArrayCollection((event.result as
ArrayCollection).source);
}
private function filterGrid():void{
dataAr.filterFunction=myFilterFunction;
dataAr.refresh();
}
private function myFilterFunction(item:Object): Boolean{
return(item.city == selectedCity || selectedCity == "All") &&
(item.location == selectedLocation || selectedLocation == "All") &&
(item.bedrooms >= selectedbdrm || selectedbdrm == "-- Choose One --")
&&
(item.bathrooms >= selectedbathrm || selectedbathrm == "-- Choose One
--") &&
(item.category == category.selectedValue)&&
(!garageSelected || item.garages)&&
(!tileflrSelected || item.tile_floor)&&
(!hardwoodflrSelected || item.hardwood_floor)&&
(!laminateflrSelected || item.laminate_floor)&&
(!balconySelected || item.balcony)&&
(!yardSelected || item.backyard)&&
(!closetSelected || item.closets)&&
(!poolSelected || item.pool);
}
private var selectedCity : String = "All";
private var selectedLocation : String = "All";
private var selectedValue: Boolean;
private var selectedbdrm : String = "-- Choose One --";
private var selectedbathrm : String = "-- Choose One --";
private var poolSelected: Boolean = false;
private var yardSelected: Boolean = false;
private var closetSelected: Boolean = false;
private var garageSelected: Boolean = false;
private var tileflrSelected: Boolean = false;
private var hardwoodflrSelected: Boolean = false;
private var laminateflrSelected: Boolean = false;
private var balconySelected: Boolean = false;
private function cityChangeHandler(event:Event):void{
if( city_cb.selectedItem != null )
selectedCity = city_cb.selectedLabel;
filterGrid();
currentState = '';
}
private function locationChangeHandler(event:Event):void{
if( lct_cb.selectedItem != null )
selectedLocation = lct_cb.selectedLabel;
filterGrid();
currentState = '';
}
private function bedroomChangeHandler(event:Event):void{
if( room_cb.selectedItem != null )
selectedbdrm = room_cb.selectedLabel;
filterGrid();
currentState = '';
}
private function bathroomChangeHandler(event:Event):void{
if( bath_cb.selectedItem != null )
selectedbathrm = bath_cb.selectedLabel;
filterGrid();
currentState = '';
}
private function categoryChangeHandler(event:Event):void{
if(category.selectedValue != null)
selectedValue = category.selectedValue;
filterGrid();
currentState = '';
vidz.player.stop();
}
private function poolFilter():void{
poolSelected = pool_ckb.selected;
filterGrid();
currentState = '';
}
private function yardFilter():void{
yardSelected = yard_ckb.selected;
filterGrid();
currentState = '';
}
private function closetFilter():void{
closetSelected = closet_ckb.selected;
filterGrid();
currentState = '';
}
private function garageFilter():void{
garageSelected = garage_ckb.selected;
filterGrid();
currentState = '';
}
private function tileflrFilter():void{
tileflrSelected = floor_tiles.selected;
filterGrid();
currentState = '';
}
private function hardwoodflrFilter():void{
hardwoodflrSelected = hardwood_floors.selected;
filterGrid();
currentState = '';
}
private function laminateflrFilter():void{
laminateflrSelected = laminate_floors.selected;
filterGrid();
currentState = '';
}
private function balconyFilter():void{
balconySelected = balcony.selected;
filterGrid();
currentState = '';
}
up to this point all is good. the problem is when i try to assign dataAr to
copydataAr
private function cloneCollection(dataAr:ArrayCollection):ArrayCollection{
var copydataAr:ArrayCollection = new ArrayCollection();
copydataAr.source = copydataAr.source.concat(dataAr.source);
return copydataAr;
that is where am having a problem and also how to apply the change effect when
data is removed or added.
