dear friends
I want to add and remove items with this simple code :
Code:
private void comboBox1_KeyDown(object sender, KeyEventArgs e)
        {

            ComboBox c = sender as ComboBox;
            if (c == null) return;
            if (c.Text == "") return;
            if (e.KeyCode == Keys.Delete)
            {
                c.Items.RemoveAt(c.FindStringExact(c.Text));
...
