SQL

if (comboBox1.SelectedText == "10")
                    comboBox2.Enabled = false;

             else if(comboBox1.SelectedText == "10+2")
                    comboBox2.Enabled = false;

            else  if(comboBox1.SelectedText == "Graduation")
{
                    comboBox2.Items.Add("BA");
                    comboBox2.Items.Add("BBM");
                    comboBox2.Items.Add("BCA");
}

            else if(comboBox1.SelectedText == "Post-Graduation")
{
                    comboBox2.Items.Add("MA");
                    comboBox2.Items.Add("MBA");
                    comboBox2.Items.Add("MCA");
}

            else if(comboBox1.SelectedText == "Doctorate")
{
                    comboBox2.Items.Add("M.tech");
                    comboBox2.Items.Add("P.hd");

C#

private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
      {
          if ("Graduation" == comboBox1.SelectedItem.ToString())
          {
              comboBox2.Items.Add("BBM");
              comboBox2.Items.Add("BCA");
          }

          if ("Post-Graduation" == comboBox1.SelectedItem.ToString())
          {
              comboBox2.Items.Clear();

              comboBox2.Items.Add("MA");
