When you add items to a ComboBox List VB.Net assigns each one an unique index number.
The first item is assigned an index of 0; the second item gets an index of 1; and so on.
For example: Index Numbers for Auto Loan Program
A -- Excellent Credit Rating = 0
B – Good Credit Rating = 1 etc ….
SelectedIndex is the property that keeps track of what index number is currently being accessed.
When no item is selected, the SelectedIndex property is set to -1. The following line of code would clear the ComboBox:
