    I tried to remove my SpecialDays by using functon 'RadCalendar1.SpecialDays.Remove(mday)
    but it seems doesn't working
     
    Private Sub RadButton1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RadButton1.Click
            Dim mdate As New Date
            mdate = RadCalendar1.SelectedDate
            Dim mDay As New Telerik.WinControls.UI.RadCalendarDay(mdate)
            RadCalendar1.SpecialDays.Add(mDay)
     
        End Sub
     
        Private Sub RadButton2_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles RadButton2.Click
           
            Dim mDay2 As New Telerik.WinControls.UI.RadCalendarDay()
            mDay2.Date= RadCalendar1.SelectedDate
               mCalendarDay.Date.ToString("dd/MM/yyyy")
            RadCalendar1.SpecialDays.Remove(mDay2)
        End Sub
    I wonder if its datetime format cause the problem?...cos it seems if i select a date e.g. '07/08/2010' (I am using en-GB format) it automatically covert it to US Datetime format when you try to remove it (Like '07/08/2010' will become '08/07/2010') , the system wouldn't throw any error, but this special day still in 'Radcalendar1.specialdays 's' List. can anybody please give me example code how to remove certain specialdays by code?
    btw, the version i got is "2009.1.9.414"
    thanks in advance! its urgent.

    ignore my first question i manage to get it remove successfully.
    For Each mSubDateStr As String In mDateStr
        For Each mSpecialDay As RadCalendarDay In cldHolidayDate.SpecialDays
            If mSubDateStr.Length > 0 Then
     
                If mSpecialDay.Date = mSubDateStr Then
                    mSpecialDay.Selected = False
                    cldHolidayDate.SpecialDays.Remove(mSpecialDay)
                    Exit For
                End If
     
            End If
        Next
     
     
    Next

    Hi zhen,

    Thank you for contacting us.

    The SpecialDays.Remove method removes only the dates that are currently stored in this collection. We do not have methods that search for specific date in the SpecialDays collection and I agree that this could be a bit confusing. We will consider improving our API to cover this scenario in our upcoming releases.

    Please consider the following code snippet  for your scenario:


    Private
    Sub radButton1_Click(sender As Object, e As EventArgs)
        Me.radCalendar1.SpecialDays.Add(New Telerik.WinControls.UI.RadCalendarDay(New DateTime(2010, 8, 5)))
    End Sub
     
    Private Sub radButton2_Click(sender As Object, e As EventArgs)
        Dim dateToFound As New DateTime(2010, 8, 5)
     
        For i As Integer = 0 To Me.radCalendar1.SpecialDays.Count - 1
            If Me.radCalendar1.SpecialDays(i).[Date] = dateToFound Then
                Me.radCalendar1.SpecialDays.Remove(Me.radCalendar1.SpecialDays(i))
                Exit For
            End If
        Next
    End Sub

    I hope this helps.

    All the best,

    Hello zhen,

    In order to implement your scenario you should subscribe for the ElementRenderer event of the RadCalendar. In this method you could apply a new cell color:
     
    Me.radCalendar1.ElementRender += New RenderElementEventHandler(radCalendar1_ElementRender)
     
    Private Sub radCalendar1_ElementRender(sender As Object, e As RenderElementEventArgs)
        If e.Day.[Date] = New DateTime(2010, 9, 6) Then
            e.Element.BackColor = Color.Red
            e.Element.DrawFill = True
        End If
    End Sub
