Do you have to take the year into account?

Here is some simple code you can modify to get what you need, just mak sure the months in you datasource are sequential.

C#

private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
       {
           comboBox2.SelectedIndex = previousMonth(comboBox1.SelectedIndex);
           comboBox3.SelectedIndex = previousMonth(comboBox2.SelectedIndex);
           comboBox4.SelectedIndex = previousMonth(comboBox3.SelectedIndex);
       }

       private int previousMonth(int sIndex)
       {
           if (sIndex == -1) return -1;
           if (sIndex == 0) sIndex = 12;
               return sIndex - 1;
       }
