Obviously, you are going to have to update the Table to save the added names.

C#

        {
            if (comboBox1.Text == "Others")
                textBox1.Visible = true;
        }

        private void textBox1_KeyUp(object sender, KeyEventArgs e)
        {
            if (e.KeyData == Keys.Enter)
            {
                comboBox1.Items.Add(textBox1.Text);
                textBox1.Visible = false;
//write a method for inserting item in cities table
DataInsert();
// write method for loading items in combobox
DataLoad();

            }
        }
