The renderers have a data property which gets refreshed under certain situations. They then follow the component lifecycle in updating their display. In theory the setter for the data property must be hit when you see things go bad. The DG has a makeRowsAndColumns method that typically does the refresh. It might be interesting to find out if and why it gets called when things go bad.

How can I 'force' it to re-render Thanks for taking the time to respond, I have been debugging it, but any other debugging suggestions would be welcomed. While debugging, I put a breakpoint at my data provider variable, and the break point is tripped whenever new data is loaded, the datagrid is instaciated etc...; however, the breakpoint is not tripped when that phenomenon of the datagrid 'refreshing' as in the video. So it's not accessing the data provider. Do you mind suggesingt some other events / variables I should watch while debugging. How can I see what events are being dispatched when I am interacting with other UI objects - can someone suggest a good in depth reference I can read up on debugging with Eclipse.

If the dataProvider or any of a number of properties change, the DG will update all the rows. The real question is whether you've handled recycling correctly or if there is some other problem. ________________________________ From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of Alan Sent: Friday, August 22, 2008 9:42 AM To: [email protected] Subject: [flexcoders] [video included] Datagrid recycle issue? How can I 'force' it to re-render Link to video: http://www.alanklement.com/download/datagrid.mov <http://www.alanklement.com/download/datagrid.mov> I understand that the datagrid is recycling cells, makes sense. I've checked out Alex's blog, but can't find a solution to this situation. Oddly enough, you can see that the datagrid refreshes correctly when I interact with display objects other than the grid itself. What events are being fired by the other display objects that are causing the grid to 'refresh'. Thanks for your time: Alan
