2 Dependent ListBoxes!

[arpan_de]

A VB6 Form has 2 ListBoxes. Both of them have 4 items. The items in the 1st ListBox are A, B, C & D. The items in the 2nd ListBox are Apple, Ball, Cat & Dog.

Assume that a user has selected B in the 1st ListBox. Under such circumstances, the item Ball in the 2nd ListBox should get selected automatically {B for ball ). Next the user selects D in the 1st ListBox. Under such circumstances, the item Dog in the 2nd ListBox should get selected automatically {D for dog ). Next the user selects A in the 1st ListBox. Under such circumstances, the item Apple in the 2nd ListBox should get selected automatically {A for apple ) so on & so forth.

How do I implement this? Also I want that if an item in the 1st ListBox is deleted, its corresponding item in the 2nd ListBox should also get deleted automatically. For e.g. if the user deletes C in the 1st ListBox, the item Cat should automatically get deleted from the 2nd ListBox {C for Cat ).

Thanks,

Arpan

If you always have the same amount of items and the corresponding items have the same ListIndex you can easily do it this way:

Private Sub List1_Click()
    List2.ListIndex = List1.ListIndex
End Sub

To delete the items you do pretty much the same way. Let's say you have a Command Button, named cmdDelete, which will delete the selected item from both lists.

Private Sub cmdDelete_Click()
    List2.RemoveItem List1.ListIndex
    List1.RemoveItem List1.ListIndex
End Sub
