Try this code. Windows Forms assumed. private void comboBox1_SelectedIndexChanged(object sender System.EventArgs e) { if(comboBox1.SelectedIndex > -1) { DateTime dt = dateTimePicker1.Value; int days = int.Parse(comboBox1.SelectedItem.ToString()); dt = dt.AddDays(days); textBox1.Text = dt.ToString(yyyy-MM-dd); } }
