Why not just set a flag instead of calling preventDefault, then check the flag afterwards.
BTW, you shouldn't be dispatching COLLECTION_CHANGE yourself. Best to use itemUpdated when changing quantity. A COLLECTION_CHANGE will fire when the default code inserts the dropped items. ________________________________ From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of bredwards358 Sent: Saturday, June 14, 2008 9:01 PM To: flexcoders@yahoogroups.com Subject: [flexcoders] Re: Help me understand custom drag/drop events I do want the dragged items inserted into the DP, I just want to add a function call to the end of that which inserts the new row into a local database table. My problem is that the for-loop which checks for duplicate entries and merely prevents the default event and updates a value in the DP makes it difficult to do what I want without doing it for every row in the DP. Here's what I have thus far: private function dragToOrders(event:DragEvent):void { var draggedItems:Object = new Object(); draggedItems = event.dragSource.dataForFormat("items"); var n:int = orderDetailArray.length; for (var i:int = 0; i < n; i++)//Looping through to check for duplicate entries { if (orderDetailArray[i].UniqueID == draggedItems[0].UniqueID) { orderDetailArray[i].Qty ++; event.preventDefault(); adgOrders.dataProvider.dispatchEvent(new CollectionEvent(CollectionEvent.COLLECTION_CHANGE)); trace("Update fired");//Placeholder foractual update function return; } adgOrders.dataProvider.dispatchEvent(new CollectionEvent(CollectionEvent.COLLECTION_CHANGE)); trace("Insert fired"); //Placeholder for actual insert function } } Works well and perfect for just putting new items into the data provider and updating current ones, but while I can update items in the both the DP and the database just fine, I just can't figure out where to put the function call to my insert function to put a new row in the DB. So basically I figured early Friday was to see if it was possible to modify the default event ever so slightly, to call the insertToDataBaseFunction(); right after the normal behavior of inserting it into the dataProvider. Looks simple, problem is, I'm just not sure where to start. --- In flexcoders@yahoogroups.com <mailto:flexcoders%40yahoogroups.com> , "Alex Harui" <[EMAIL PROTECTED]> wrote: > > IIRC, the DragDrop event is the right place and you were already doing > that.
