I have a confused issue
There is a listbox and it's items is also listbox I want to do something when double the subitem listbox's item
when the subitem listbox is not show full, click it's item once, the listbox will show full and the item's position will change,so can not double click the item
as the attach pic show I can double click the "aaa" item but can not doube click the "bbb" item when the second listbox is not show full
Is any solution to resolve this issue?
