The DataGrid does not update the dataProvider until you switch to a new row. Editing different columns in the same row doesn't cause an update in order to minimize update event traffic.
There are past topics on this issue in the archive. Usually, I recommend cheating by getting the ITEM_EDIT_END event and change the reason to NEW_ROW if it was NEW_COLUMN Alex Harui Flex SDK Developer Adobe Systems Inc.<http://www.adobe.com/> Blog: http://blogs.adobe.com/aharui From: [email protected] [mailto:[email protected]] On Behalf Of elnomdeguerre1 Sent: Wednesday, March 11, 2009 4:04 PM To: [email protected] Subject: [flexcoders] Datagrid Display update problem HI, I know that there have been lots of discussion about the datagrid topic but I simply couldn't figure this bug out. I have a datagrid with a custom editor and renderer that displays an amount. Based on this amount I make a calculation which is then displayed in an adjacent uneditable cell. When the focus leaves the first cell the second cell is not updated immediately, I have to change focus to either outside the datagrid or to another row in the datagrid for the calculated amount to show up. I do call the the Datagrid(owner).invalidateList() function and I've tried the IList(dataprovider).itemupdated(data) function as well. None of them seem to work... I've even called invalidateDisplayList in desperation. The cell that is supposed to display the data has a custom itemrender(label), which does nothing but change the color of the text based on some other variable and assign text= data.CalculatedAmount on DataChange. I've debugged through this method and I do see that the data is is there, and it is assigned but it simply isn't shown on the screen. I'm really at my wit's end with this problem. Any help would be greatly appreciated.
