Try using the UpdateItems and Refresh methods for your TListView. You've cleared the items but it might not be redrawing it

The Neil
Items.Clear deletes all record that are stored in Items, so it should work, another issue if you are doing time consuming thing afterwards, e.g. immediatly after Items.Call, TListView is not updated.
chiwan: Are you associating objects with each item in the listview? If so, you will need to free the objects yourself, Items.Clear will not do this for you. You could do it like this:

for I := 0 to listview.items.count - 1 do

I have tried both methods you point out,
but not work. I am just wonder should
I distroy Tlistview before I start a
new search.

Thank& Rgds

Can you calrify what you mean by "the old records still inside".

Perhaps if you showed us the code where you populate the list view it would be clearer...
