Hi all,
In the attached code, I need to have the following options
1) get the name(eg;first.doc) of the selected item/items.
2) When I right click on top of a particular item, I need to have that item alone selected.
3) I need to have no selection for elements once I click outside the list.
I am attaching the code I developed, here.
Kindly help implementing these.
Any help is greatly appreciated.
