Viraf - When you say "each cell in the grid contains 4 other objects that are displayed", it sounds like you are using a custom cell renderer. Is that right?
Unfortunately, large DataGrids with custom cell renderers are a known performance issue. I'm afraid I can't completely solve your problem on Flex v1.5. You might want to turn off live scrolling, so that the DataGrid doesn't attempt to constantly update while the user is dragging the slider thumb. We've already spoken publicly about the performance improvements coming in Flash Player 8, so it should be no surprise that performance is a major focus of Flex v2.0. Viraf - would you be willing to send us a copy of your app, so that we can use it as a performance test case for the next release? Or ... even better ... could you create a simple version of your app that just contains the poorly-performing DataGrid? If so, please send it directly to me at my work address - [EMAIL PROTECTED] Other folks on the list - this is an open invitation to send along your performance test cases too! We ordinarily discourage people from contacting employees off-list, but I'll make an exception in this case.
