It occurred to me that if you subclass, you can block the DG from seeing some of the collectionevents and therefore block the full update. Then, if you find another way to notify the renderer (binding may work) then you can probably optimize the update.

But regardless of that I really was just wondering whether there was some other way of doing it that could bypass this refresh everything approach becuase I am just changing one field but the grid is big lots of columns and rows and redrawing the whole thing is very very slow. A sort of "redraw the current row" method, I guess the answer is no then... --- In [email protected] <mailto:flexcoders%40yahoogroups.com> , "Alex Harui" <[EMAIL PROTECTED]> wrote: > > All rows are redrawn in case other rows were doing something related as > well. 4ex, a labelfunction could look fwd or back a row. > > > > ________________________________ > > From: [email protected] <mailto:flexcoders%40yahoogroups.com> [mailto:[email protected] <mailto:flexcoders%40yahoogroups.com> ] On > Behalf Of ben.clinkinbeard > Sent: Tuesday, October 23, 2007 5:52 AM > To: [email protected] <mailto:flexcoders%40yahoogroups.com> > Subject: [flexcoders] Re: Updating a field in a Collection bound to > DataGrid > > > > Just shots in the dark here but is your collection filled with > strongly typed objects?
