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.
