Please how can i code a combobox in my software to be able to update itself whenever a new item is keyed in so that it automatically becomes a member of the combobox dropdown list.the combobox should be able to update itself with new items so that users will be able to choose an item from the combobox dropdown or type a new item to be saved.I know that SQL might be used.Please how can i code that.

1. Add new item on database
