MySqlConnection con = new MySqlConnection("connection...");
con.Open();
MySqlCommand cmd = con.CreateCommand();
cmd.CommandText = "select Date from inventoryout";
MySqlDataReader reader;

reader = cmd.ExecuteReader();
DataTable dt = new DataTable();
dt.Columns.Add("Date", typeof(String));
dt.Load(reader);

cbFrom.ValueMember = "Date";
cbFrom.DisplayMember = "Date";
cbFrom.DataSource = dt;

cbTo.BindingContext = new BindingContext();
cbTo.ValueMember = "Date";
cbTo.DisplayMember = "Date";
cbTo.DataSource = dt;
