Hi Venkat,
I have tried with your code i still have the same issue. After
selecting value from ComboBox(change the combobox value of min 2 or 3
rows), move the cursor out of datagrid(completely outside to datagrid)
upside/downside. An vertical scroll bar is happening on datagrid.I
have tried the same example in Flex 3 did not get this issue. I hope
this might be a bug in Flex 2.
Regards,
Malavika.
