Hi @bob fitz thank you for your reply. i just used me.Listview3.enabled = false.
and the other issue that i encounter is whenever i enable it using me.listview3.enabled = true. the left position will become zero and top position will become zero.
Strange behavior is often a symptom of corruption.
Perhaps delete the list box and recreate it or even replace the entire form.
I'm sure a search of the forum would give much advice on corruption.
