Hi Gnana,
Thanks for the info...
What i was developing was a bit different with yor example.
On change in the datagrid, i want to pass the selected data from the array
collection into the view stack components.
in the example, u specified, i don't actually click the on the linkbar,
which would change the selectedIndex.
with the click on the datagrid, i need to pass the selected data to all the
view stack components and display that selectedItem data accordingly....
so i need to call the individual view stack components methods , so that i
could invoke them and perform necessary actions...
Think am confusing you... please let me know if u need further
clarificatrion.
Thanks,
Madan N
