[flexcoders] Custom Component Height issue

[flexlearner19]

hi all

i am using a custom component (extended spark panel ,added some buttons on the 
header)and that  contains a datagrid.now my problem  is whenver I add a row  to 
the datagrid,the panel is not  updating it s height.So that i get a scrollbar  
in the datagrid. I need to avoid the scrollbar.


  any ideas to fix this ...please help..
