Re: [Junk E-Mail - LOW] [flexcoders] DataChange event in DataGrid
--- Chaitu Vadlapatla [EMAIL PROTECTED] wrote: Hi tracy, did you manage to find a way to do the dataChange fire off. Thanks Chaitu. Hi Chaitu Yes, I did manage to get the dataChange to work, but I did change the code slightly. The latest Flex documentation says that one should use ArrayCollections as a dataProviders for list-based controls, rather than Arrays, and one can catch the relevant events from there (read Flex Developer's Guide on flex.org) For my grids I did the following: - added a function to be called on the grid's creationComplete event: creationComplete=initDataChange(event) - in that function I added a collectionChange event listener: grid.addEventListener(collectionChange, collectionChangeHandler ) So when my ArrayCollection variable in the model changed, it would fire a collectionChange event, which would be captured by the DataGrid (since it was wired up to listen for it in the initDataChange function) and call the collectionChangeHandler(event) function.

RE: [Junk E-Mail - LOW] [flexcoders] DataChange event in DataGrid
Exactly how are you changing the data? Perhaps I'm blind. I
don't see the grid as editable, nor do I see any function changing the
data.

My bad... I was blind.
You need to cast your dataprovider as an arrayCollection,
not an array.

Looks like now you want to use the
arrayCollection.collectionChange event to trap it.
