As you are adding new item to the database from the popup window, you will have to call the populateListView method again after the form is closed. This will solve your problem

Post your code for opening the popup window by Improving your question

if you are displaying the popup window using the showdialog method then call populateListView after showdialog method is called. it will automatically get executed after the popup window is closed.
