I wirte an ItemRenderer (override set data and updateDisplayList functions), inside this ItemRenderer I change background color for cell when new value not equal old value(I use ArrayCollection set dataProvider property for ADG). And then, set this ItemRenderer to AdvancedDataGrid. All things were ok, but when i make scroll on ADG, changing color for cell not correct. Here, row index of ADG not right when scroll event happened. Have any event scrolls for ADG ?
