Yes, that is entirely possible and somewhere I have the code for it which I will look out and post for you. The only problem is that the lists cannot work dynamically. By this, I mean if you select a department from one list and then an employee from another list, if you then go back and change the department, the employee that you originally selected will still be showing. There is no way I know to make a selection in one list affect other cells wothout resorting to VBA I would guess.
Anyway, I will have a dig around on my PC tonight and try to find that code I spoke of. If I remember correctly, it only uses two lists, a selection in the first determining the values you can select in another but it will certainly give you the idea. One caveat, it exploits a loop-hole in Excel where using POI we can create data validations using named areas on other sheets. This is likely only to be a problem if you need to modify the formula that is used to populate the lists through Excel itself rather than through POI. Once I have the code, I will try to explain this 'problem' a little more clearly and also outline the - very easy - solution. Yours Mark B PS I was working on an example for the POI website demonstrating the various different ways to build data validations and became sidetracked by other problems. This has convinced me to complete that work, sooner rather than later. nagineni wrote: > > 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. > > Regards, > Naga. > > MSB wrote: >> >> Forgive me answering a question with a question please but is this even >> possible using Excel itself?
