Imagine yourself in a dimly lit corridor, making your way toward a faint cry for help. As you approach "RAWR" is this scary fire breathing dragon! OMG now is a perfect time to get your arcanite reaper, which hopefully is SelectedIndex(0) bcz you dont have a lot of time here. To make a long story short, after a long and cumbersome exhaustive battle you have slain your enemy and smote his ruins in the fiery hell from which he haled. Now is where you can utilize your SelectedItem to rescue the princes and live happily ever after...

Let's say you have a ComboBox that contains a list of names:

Aaron
Ben
Chris
David
Edgar
Frank
...

SelectedItem would give you the name that was selected, so if you select David it gives you David, if you select Aaron, it gives you Aaron.

SelectedIndex would give you the numeric position in the list (starting at 0) that is selected, so if you click Aaron it gives you 0, if you click Ben it gives you 1, if you click Chris it gives you 2, and so on. This would be useful if you have a parallel array that contains other information about the people in the list. You would use SelectedIndex to retrieve that other information from the parallel array.

Example: You have an array called DateOfBirth() that contains the Dates that each person in the list was born in (in the same order that they appear in the ComboBox), and you have a text box that you want to display the birthday of the person selected from your ComboBox.

You would do something like this:

txtBirthDate.Text = DateOfBirth(cboComboBoxName.SelectedIndex).ToShortDateString
