I'm loading a ComboBox:

cboType.Items.Add("Book");
cboType.Items.Add("CD");
cboType.Items.Add("DVD");
cboType.Items.Add("Periodical");
cboType.Items.Add("Tape");

The I want to set it's selected index:

cboType.SelectedIndex = iItem;

This errors because cboType.Items.Count is zero.

What's wrong here?
