I have two combo boxes on a dialog window.

The aim is to check the the strings of the items. But if no items are
selected then this line crashes the program.

if (comboBox1.SelectedItem.ToString() == comboBox2.SelectedItem.ToString())

Click to expand...

If the SelectedIndex property is -1, there is no current selection.
