[Solved] Week number

[Kjell]

I'll try to get the week number from RadDatePicker SelectedDate

<telerik:RadDatePicker ID="rdpDatum" width="0" PopupDirection="BottomRight" Runat="server">
 <Calendar UseColumnHeadersAsSelectors="False" UseRowHeadersAsSelectors="False" runat="server" />
 <DateInput style="display:none;" DisplayDateFormat="yyyy-MM-dd" runat="server" />
</telerik:RadDatePicker>

I found examples in the forum threads http://www.telerik.com/forums/radcalendar-weeknumber
But have error, see attached file.
Post is from 2010, tips on how I can get the week number?

Hi Kjell,

Please do the following modifications in your code which works fine at my end.

VB:

Protected Sub RadButton1_Click(sender As Object, e As System.EventArgs) Handles RadButton1.Click
    Dim dt As DateTime = rdpDatum.SelectedDate
    Dim number As Integer = GetWeekNumber(dt)
    Dim year As Integer = dt.Year
End Sub
Public Function GetWeekNumber(dtDate As DateTime) As Integer
    Dim ciCurr As CultureInfo = CultureInfo.CurrentCulture
    Dim weekNum As Integer = ciCurr.Calendar.GetWeekOfYear(dtDate, CalendarWeekRule.FirstFourDayWeek, DayOfWeek.Monday)
    Return weekNum
End Function

Thanks,
Shinu.
