[flexcoders] Re: Synchronizing two ArrayCollections
Thanks that worked beautifully my final code follows:
private function dgClick():void {
var curTick:String = dgOrdExt.selectedItem.Ticker;
for (var i:int = 0; i Array_Exits.length; i++)
{
if ( Exits(Array_Exits.getItemAt(i).Ticker ==c urTick)
{
dgExits.selectedIndex = i;
}
}
}

Depending on your model, you could use for each instead. Also, replace
dg2.dataProivider with the appropriate ArrayCollection name and replace
Object with your VO class name; if you're using one. I'd use the
change event instead of click.

[flexcoders] Re: Synchronizing two ArrayCollections
Cool, I kind of like this way better though:
private function dgClick():void
{
var curTick:String = dgOrdExt.selectedItem.Ticker;
for each ( var exits:Exits in Array_Exits )
{
if ( exits.Ticker == curTick )
{
dgExits.selectedIndex = Array_Exits.getItemIndex( exits
);
}
}
}
A little cleaner than using a counter.
