Hi jyothi It's simple.. Write the method to load the Combobox from database. Call the method after the child form called code.. Ex : Childform c=new Childform() C. ShowDialog () LoadCombobox()

Hi Jyothi You can use datatable for displaying adding purpose finally save into database. for example Form1 by default load the db master data and same data copy to datatable/dataset . In Form2  You can adding new customer name . This name save /add to datatable not database. After adding datatable reload/bind the datatable data to combobox in the form1. This similarity task i have done with web application not windows application. Try you can happy code :).
