du skal gøre det, at du abbonnerer på det event der hedder dayrender. i handleren for du et argument med du kan bruge - f.eks. kan du
e.Day.Cell.Controls.Add(new LiteralControl("blah"));
hvilket medører at du få smidt en tekst ind i cellen for den aktuelle dag.... nu er det ikke det du vil, men jeg tror ikke du har andre muligheder for at manipulere med kontrollen i det henseende.
du skal self. også have fat i ugenummeren ud fra den aktuelle dato, hvilket du må finde en algoritme til... jeg har brugt en i nedenstående eksemple jeg har googlet op - har ikke verificeret om den holder.
den kommer herfra:
http://konsulent.sandelien.no/VB_help/Week/(og der kan sikkert findes mange andre på nettet)
protected void Page_Load(object sender, EventArgs e)
{
}
protected void Calendar1_DayRender(object sender, DayRenderEventArgs e)
{
string weekNumber = String.Format("[{0}]", GetWeekNumber(e.Day.Date));
e.Cell.Controls.Add(new LiteralControl(weekNumber));
}
private int GetWeekNumber(DateTime date)

// Updated 2004.09.27. Cleaned the code and fixed a bug. Compared the algorithm with
// code published here . Tested code successfully against the other algorithm
// for all dates in all years between 1900 and 2100.
// Thanks to Marcus Dahlberg for pointing out the deficient logic.
// Calculates the ISO 8601 Week Number
// In this scenario the first day of the week is monday,
// and the week rule states that:
// [...] the first calendar week of a year is the one
// that includes the first Thursday of that year and
// [...] the last calendar week of a calendar year is
// the week immediately preceding the first
// calendar week of the next year.
// The first week of the year may thus start in the
// preceding year
const int JAN = 1;
const int DEC = 12;
const int LASTDAYOFDEC = 31;
const int FIRSTDAYOFJAN = 1;
const int THURSDAY = 4;
bool ThursdayFlag = false;
// Get the day number since the beginning of the year
int DayOfYear = date.DayOfYear;
// Get the numeric weekday of the first day of the
// year (using sunday as FirstDay)
int StartWeekDayOfYear =
(int)(new DateTime(date.Year, JAN, FIRSTDAYOFJAN)).DayOfWeek;
int EndWeekDayOfYear =
(int)(new DateTime(date.Year, DEC, LASTDAYOFDEC)).DayOfWeek;
// Compensate for the fact that we are using monday
// as the first day of the week
if (StartWeekDayOfYear == 0)
StartWeekDayOfYear = 7;
if (EndWeekDayOfYear == 0)
EndWeekDayOfYear = 7;
// Calculate the number of days in the first and last week
int DaysInFirstWeek = 8 - (StartWeekDayOfYear);
int DaysInLastWeek = 8 - (EndWeekDayOfYear);
// If the year either starts or ends on a thursday it will have a 53rd week
if (StartWeekDayOfYear == THURSDAY || EndWeekDayOfYear == THURSDAY)
ThursdayFlag = true;
// We begin by calculating the number of FULL weeks between the start of the year and
// our date. The number is rounded up, so the smallest possible value is 0.
int FullWeeks = (int)Math.Ceiling((DayOfYear - (DaysInFirstWeek)) / 7.0);
int WeekNumber = FullWeeks;
// If the first week of the year has at least four days, then the actual week number for our date
// can be incremented by one.
if (DaysInFirstWeek >= THURSDAY)
WeekNumber = WeekNumber + 1;
// If week number is larger than week 52 (and the year doesn't either start or end on a thursday)
// then the correct week number is 1.
if (WeekNumber > 52 && !ThursdayFlag)
WeekNumber = 1;
// If week number is still 0, it means that we are trying to evaluate the week number for a
// week that belongs in the previous year (since that week has 3 days or less in our date's year).
// We therefore make a recursive call using the last day of the previous year.
if (WeekNumber == 0)
WeekNumber = GetWeekNumber(
new DateTime(date.Year - 1, DEC, LASTDAYOFDEC));
return WeekNumber;
}
og i aspx'en har du så noget i denne stil:
<asp:Calendar ID="Calendar1" runat="server" OnDayRender="Calendar1_DayRender"></asp:Calendar>
nu skriver den så bare et ugenummer ud for hver dag - og det skal du så mingelere lidt med.... men det skulle da være et udgangspunkt.
mvh
