How to change the column text header name?

Asked by jordjmax

Since it is only for one day, i would like to display today instead of monday. Attached are my images, there are limited event handler so hope it can be solved.

public partial class number2 : System.Web.UI.Page
protected void Page_Load(object sender, EventArgs e)
if (!IsPostBack)
DayPilotCalendar1.StartDate = DayPilot.Utils.Week.FirstWorkingDayOfWeek(new DateTime(2014, 04, 03));
//DayPilotCalendar1.StartDate = DayPilot.Utils.Week.FirstWorkingDayOfWeek(DateTime.Now.AddDays(-(int)DateTime.Now.DayOfWeek).Date);
DayPilotCalendar1.DataSource = dbGetEvents(DayPilotCalendar1.StartDate, DayPilotCalendar1.Days);


private DataTable dbGetEvents(DateTime start, int days)
string constr = ConfigurationManager.ConnectionStrings["ProjectConnectionString"].ConnectionString;
SqlDataAdapter da = new SqlDataAdapter("SELECT ID, PURPOSE, [START_DATE], [END_DATE], [START_TIME], [END_TIME] FROM [Schedule]", constr);
da.SelectCommand.Parameters.AddWithValue("start", start);
da.SelectCommand.Parameters.AddWithValue("end", start.AddDays(days));
DataTable dt = new DataTable();

for (int i = 0; i < dt.Rows.Count; i++)
dt.Rows[i]["START_DATE"] = CombineDateAndTime(dt.Rows[i]["START_DATE"], dt.Rows[i]["START_TIME"]);
dt.Rows[i]["END_DATE"] = CombineDateAndTime(dt.Rows[i]["END_DATE"], dt.Rows[i]["END_TIME"]);

return dt;

public static DateTime CombineDateAndTime(object date, object time)
if (date == null)
// Add some logic for this scenario. Here are 2 examples:
//throw new ArgumentNullException("date");
//date = DateTime.MaxValue;
if (time == null)
// Add some logic for this scenario.
//throw new ArgumentNullException("time");
//time = 0;

DateTime dt = Convert.ToDateTime(date);
float hoursAndMinutes = Convert.ToInt32(time);

return CombineDateAndTime(dt, hoursAndMinutes);
public static DateTime CombineDateAndTime(DateTime date, float time)
int hours = Convert.ToInt32(Math.Round((decimal)time / 100, MidpointRounding.AwayFromZero));
float remainder = time - (hours * 100);
int minutes = Convert.ToInt32(Math.Round((decimal)remainder, MidpointRounding.AwayFromZero));
DateTime returnDate = date.Date.AddHours(hours).AddMinutes(minutes);
return returnDate;

There is no built-in mechanism for customizing the column header in the Lite version. You will have to modify the source code.
