I have a program which fetches some data from database and shows it as a list on the Frame.When I click a button to fetch the data it works fine and displays the list populated with the data.But again when i click it works fine but a new list is created .I want to remove the earlier list and present the new list in its place. I also posted thew code extract in this forum with heading layout problem but got no response yet.I have tried using invalidate but without any success.Any idea??
