Subject Re: How to disable list box values in XLS using POI
Date Thu, 19 Nov 2009 15:50:57 GMT

Thanks Mark for the given idea of using dynamic drop downs.Yes,This way is
one solution to the problem.
But other issue is I've various levels of drop downs depends on each
other.Here is an example as you said ,three drop downs of orginfo,branchinfo
and empinfo.If I change first drop down ,the second should populate
values,If I change second one ,third should populate it's values...like that
I've many levels.

Is this can be achieved in POI ?Sample code could be more helpful.Great
thanks for the help.
