must you set that click event in the
Private Sub _menuWeekRange_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles _menuWeekRange.Click
   _calendar.CurrentView = CalendarView.WeekRange
         End Sub

or is that an seperate method

you know i have a demo with 3 calendars but when i want to save and load them he gives nothing back on the timetable

Private Sub _menuSave_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles _menuSave.Click

       _calendar.Schedule.Save("schedule.save")
       Calendar1.Schedule.Save("schedule.save")
      Calendar2.Schedule.Save("schedule.save")

    End Sub

    Private Sub _menuLoad_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles _menuLoad.Click

       _calendar.Schedule.Load("schedule.save")
       _calendar.Invalidate()
        Calendar1.Schedule.Load("schedule.save")
        Calendar1.Invalidate()
        Calendar2.Schedule.Load("schedule.save")
        Calendar2.Invalidate()
    End Sub

i changed like you see but when i save it he gives nothing back

i have a question can you fill the timetable from an sql mobile 2005 database or is it only in xml file

oh so you have never tried it before
i must read it out from a sql mobile database into the timetable and also save the new appointments
haven't you any example of that or some more specifik information because i have never done that before 

wel for the loading and saving of the appointments i don't know how to start
maybe i must start with creating an appointment object and assign the values to their properties.

Regarding scrollbars in WeekRangeView - they are displayed only when needed, i.e. not all contained days are visible at a time. To show a vertical scrollbar, you either select wider range of dates by using Calendar.Date and Calendar.EndDate, or you choose less days to be visible at a time, by reducing the number of visible rows in the view (Calendar.WeekRange.VisibleRows).

As for saving and loading appointments you can either save the entire schedule to a string by calling Schedule.SaveToString, then writing this string to the SQL database, or save appointments individually, which would require some efforts.

I am not sure I understand that last post - do you need to save all three schedules in the same file ?
