Hi Deepak, I also had that problem, this one is easily fixed by editing the skin.
inside the scroller it looked like this: <s:Grid id="grid" itemRenderer="spark.skins.spark.DefaultGridItemRenderer"> <s:GridLayer name="backgroundLayer"/> <s:GridLayer name="selectionLayer"/> <s:GridLayer name="editorIndicatorLayer"/> <s:GridLayer name="rendererLayer"/> <s:GridLayer name="overlayLayer"/> </s:Grid> now it looks like this: <s:Grid id="grid" itemRenderer="spark.skins.spark.DefaultGridItemRenderer"> <s:gridView> <fx:Component> <s:GridView> <s:GridLayer name="backgroundLayer"/> <s:GridLayer name="selectionLayer"/> <s:GridLayer name="editorIndicatorLayer"/> <s:GridLayer name="rendererLayer"/> <s:GridLayer name="overlayLayer"/> </s:GridView> </fx:Component> </s:gridView> </s:Grid> Hope it helps you.
