[flexcoders] Re: Multiple ItemRenderers for a single DataGridColumn
Oh my, what a difference! I didn't know about this function. Extended DataGrid, override createColumnItemRenderer, now my code is much cleaner and it actually completely took care of my performance issue on this grid. I still need to run it through the profiler to make sure that I'm not doing anything stupid inside of it since it fires so often. Does their happen to be a function or event for when a renderer is no longer being displayed? I'd like to create a pool and reuse the renderers as right now I'm creating new in this function. That's the reason I want to run it through the profiler. Thanks a bunch!

To my great displeasure I don't see the createColumnItemRenderer function in the AdvancedDataGrid. What do you suggest for the AdvancedDataGrid as I have the same issue here.

RE: [flexcoders] Re: Multiple ItemRenderers for a single DataGridColumn
ADG is developed by an entirely different team. They have an undocumented method called columnItemRenderer that has the same function signature and looks like it does the same thing.

[flexcoders] Re: Multiple ItemRenderers for a single DataGridColumn
Hi Dale, An itemRenderer is a component. You can use states within an itemRenderer; that are conditionally set. If you override the set data method, you can change the component's state there; to meet your needs. You could also use a viewStack in the itemRenderer and do the same thing. -TH --- In flexcoders@yahoogroups.com, dbronk [EMAIL PROTECTED] wrote: I have a DataGrid and one of the columns I need to be able to do the following based on the user security setting and the data in the column.
