Is there a way to check if a combobox or listboxitem is visible on screen?

Question

If a listbox has many items, is there a way (programatically) to check if an item is visible on screen.

For example, the listbox has 100 items, but only first 24 are shown of the screen, is there a way to check if a specific (say list[75]) is currently displayed or one should scroll to see it?

Answer 2

Check Calculating number of visible items in ListBox and look for my post below.

I've seen to many complex answers that are not correct.

Short answer: (listBox1.Height/ listBox1.ItemHeight)
