Java list (dropped down)box has more items and each item has checkbox to select an item. We need to check all items in the list box using QTP tool. QTP is good interms of selecting (checking) the items which are visible but after that it is getting hung. I guess, this is due to the item that is invisible. QTP knows that there is an item exist but for that, it has to down the scroll bar to select an invisible item. So, using QTP, how can i know what list items are invisible? and what is the QTP procedure to down the list scroll bar?
