Yes, I think that's a nasty little component because it has the functionality of a mushroom. I typically use a modified AdvancedDataGridGroupItemRenderer to render all columns. > 3) Yes, the styleFunction does get called when the highlighted object > changes.

I wouldn't be trying to change the data itself in respons to a ui change, since it's almost inevitably going to trigger another ui change. HTH; Amy
