I am getting this: Sys.WebForms.PageRequestManagerParserErrorException error pops saying "Error parsing near Begin:VCALENDAR " or something similar... The Export Button above the Scheduler doesn't throw this error, only when clicking on the Export buttons inside the calendar. However when I try to import the .ICS file that is generated from the 'above the scheduler export button', Outlook barks and throws this error:
Microsoft Office Outlook cannot import vCalendar file. This error can appear if you have attempted to save a recurring Lunar appointment in iCalendar format. To avoid this error, set the appointment option to Gregorian instead of Lunar.
Can anyone help me get this Export to ICS working? it works on Teleriks site - what am I doing wrong I'm going nuts and will be a big hero once this works right! lol

Hello Trevor,

We have received reports for the first error already ("Error parsing..."), but we still cannot reproduce it locally. Have you modified the example when running it on your machine? Any additional details you can provide about the browser/operating system and regional settings you are using will also help us diagnose the problem.

Regarding the Outlook error - does it happen with the file generated from our site? Can you quote the generated file here. What version of Outlook are you using?

Okay the sys.webforms parsing error happens whether I preview it in VS 2005 using the internal (Cerini) web server, or if I push it up to my win2k dev web server running IIS. To answer your question, it works perfect when I view the demo on your site - and even the generated Outlook .ICS file imports into my Outlook 2003. So I know this can be made to work!! lol Also I've even tried using my same code - but stripped out the extra stuff/formatting/DHTML menus, etc.... and while the Javascript error I am having goes away, the sys.webforms error persists.

Here is my ASPX and VB Code Behind - hopefully something I'm doing wrong will jump out at you guys. Thanks for your help.

ASPX Page - note the crazy javascript is for my rollovers and DHTML menus I have on the page.... the way I am calling the ASP:Scheduler should be just like the Telerik sample more or less.

Hello Trevor,

I think we have found the problem - one of your buttons is named "submit" and due to the specifics of the JavaScript form object it messes up the form.submit() method. JavaScript can be too dynamic at times, but the workaround is easy enough - rename your button to "submitButton" or something different.

I need a little more help understanding something... Everything works now - but when I click the Export button in the scheduler control on a day, it's creating the iCalendar file and pops open Outlook....but the date or time is always off. Even when I set the TimeZoneOffset Property to 0:00:00 and my Rad:Scheduler and SQL database show the same info - when I export the appointment (using the sample code you provide) it's always off by numerous hours... How do I get the Export to be the same as what they are seeing on the Calendar? My Outlook is 2003. I just want my export to always be the same thing that's in my SQL.

Hi Trevor,

I acknowledge this shortcoming in the current version. The problem is that in the exported file the time is marked as UTC, otherwise it is unchanged. When you import this data it gets converted to local time, hence the difference.

We have addressed the issue in the upcoming Service Pack by adding two new overloads to the RadScheduler.Export method. They take a TimeSpan as a parameter and add it to the appointment.

For example, you will be able to use:

TimeSpan currentOffset = TimeZone.CurrentTimeZone.GetUtcOffset(DateTime.Now); 
string iCal = RadScheduler.Export(apt, currentOffset); 

The service pack is due in a few days.

Kind regards,

I would like to see more fields available for export to calendar format. Sometimes you need more info in the calendar file than is exported.  A URL to the calendar page is a nice touch.  Until I can get the fields I need from the control's method, I use something like this in an .ashx file.  This eliminates the parser error when call write() method, too.
public void ProcessRequest(HttpContext context)  
 {  
   HttpResponse response = context.Response;  
   HttpRequest request = context.Request;  
   response.BufferOutput = true;  
   response.ContentType = "text/calendar"
   response.AddHeader("Content-disposition", "attachment;  filename=appointment.vcs");  
   response.Cache.SetCacheability(HttpCacheability.NoCache);  
//your appointment id    
  int ID = Convert.ToInt32(request.QueryString["ID"]);  
//your method to query the database and write your own output 
   writeEntry(EventID, response.Output);  
   response.End();  
 } 
in the writeEntry method, do things like this using the values from your appointment table row.  (note: forming a vCalendar, iCalendar is probably newer than this code)
output.WriteLine("BEGIN:VCALENDAR"); 
 
            output.WriteLine("VERSION:2.0"); 
            output.WriteLine("PRODID:" + url); 
            output.WriteLine("METHOD:PUBLISH"); 
            output.WriteLine("BEGIN:VEVENT"); 
            output.WriteLine("UID:" + Guid.NewGuid().ToString()); 
            output.WriteLine("DTSTAMP:" + DateTime.Now.ToUniversalTime().ToString("yyyyMMddTHHmmss") + "Z"); 
            output.WriteLine("CATEGORIES:APPOINTMENT;PERSONAL"); 
            output.WriteLine(EncodeProperty("DESCRIPTION;ENCODING=QUOTED-PRINTABLE:", description)); 
            output.WriteLine("DTEND:" + endtime.ToUniversalTime().ToString("yyyyMMddTHHmmss") + "Z"); 
            if (!(location == null)) 
            { 
                output.WriteLine(EncodeProperty("LOCATION;ENCODING=QUOTED-PRINTABLE:", location)); 
            } 
            output.WriteLine("PRIORITY:0"); 
            output.WriteLine("DTSTART:" + starttime.ToUniversalTime().ToString("yyyyMMddTHHmmss") + "Z"); 
            output.WriteLine("STATUS:NEEDS ACTION"); 
            output.WriteLine(EncodeProperty("SUMMARY;ENCODING=QUOTED-PRINTABLE:", title)); 
            output.WriteLine("URL:" + url); 
            output.WriteLine("END:VEVENT"); 
 
            output.WriteLine("END:VCALENDAR");

Can you help me with this sub? I tried converting the C# example you gave me to VB but it's not working right...

Protected Sub RadScheduler1_AppointmentCommand(ByVal sender As Object, ByVal e As AppointmentCommandEventArgs)

Dim currentOffset
currentOffset = TimeZone.CurrentTimeZone.GetUtcOffset(DateTime.Now)

If e.CommandName = "Export" Then
WriteCalendar(RadScheduler.ExportToICalendar(e.Container.Appointment, currentOffset))
End If
End Sub

Hello Trevor,

Could you please be more specific what exactly happens when you use this code? Do you get a compilation error or is the export output not correct? Also, do you use the latest version of RadScheduler from the service pack we released Wednesday, this week?

If I use that code (above) and my RadScheduler TimeZoneOffset property is set to 00:00:00, then the datebase AND the scheduler show the same time - good I like that. But when I click Export, it pops up and is 12 hours behind. Example: Appt says 2am-3am instead of 2pm-3pm like the scheduler shows..

Hello Trevor,

We replied in the other forum thread about this issue. Here is the answer:

"True, the time frame of the appointments is off when exported. It looks like we have missed one small detail - the currentOffset argument should be passed with a "-" sign.

WriteCalendar(RadScheduler.ExportToICalendar(e.Container.Appointment, -currentOffset))"


Kind regards,

Okay... Here is my latest stab at getting this to work. This time I am using the '-' currentOffset and I still have a werid Export time. Outlook opens up and say's a 1pm-2pm on 11/14/07 appt is a 9pm-10pm appt on 11/13/07!!!  now what.... here's my code.    

Protected Sub RadScheduler1_AppointmentCommand(ByVal sender As Object, ByVal e As AppointmentCommandEventArgs) Handles RadScheduler1.AppointmentCommand 

Dim currentOffSet As TimeSpan = TimeZone.CurrentTimeZone.GetUtcOffset(DateTime.Now)

Dim iCal As String = RadScheduler.ExportToICalendar(e.Container.Appointment, -currentOffSet)

 If e.CommandName = "Export" Then

 WriteCalendar(iCal)

 End If
End Sub

Hello Trevor,

Please, ignore the last suggestion. We are sorry for misleading you, the time zone offset should be passed in without a minus sign.

The real problem turned to be a bug in our code. I am attaching a trial hotfix here.

I am using Q3 controls and am having problems with the export of appointments from radscheduler.  I have implemented the offset as suggested here:

TimeSpan currentOffset = TimeZone.CurrentTimeZone.GetUtcOffset(DateTime.Now);
WriteCalendar(RadScheduler.ExportToICalendar(e.Container.Appointment,currentOffset));

However, my  appointments are still showing up as one hour later.  Is there something that has changed in Q3 to make the exports work correctly for exports?

Hi Debbie,

This might be a result of Daylight Saving Time changes. If the appointment is created before the DST transition, it will be off by one hour. We can take the time zone offset for the date when the appointment is created to correct this:

DateTime aptStart = DateTime.SpecifyKind(e.Container.Appointment.Start, DateTimeKind.Local); 
TimeSpan currentOffset = TimeZone.CurrentTimeZone.GetUtcOffset(aptStart); 
WriteCalendar(RadScheduler.ExportToICalendar(e.Container.Appointment, currentOffset)); 
 

Let us know how it goes.

Sincerely yours,

This fixed the problem:
    Protected Sub RadScheduler1_AppointmentCommand(ByVal sender As Object, ByVal e As AppointmentCommandEventArgs)  
        If e.CommandName = "Export" Then  
            Dim aptStart As DateTimeDateTime = DateTime.SpecifyKind(e.Container.Appointment.Start, DateTimeKind.Local)  
            Dim currentOffset As TimeSpan = TimeZone.CurrentTimeZone.GetUtcOffset(aptStart)  
            WriteCalendar(RadScheduler.ExportToICalendar(e.Container.Appointment, currentOffset))  
        End If  
    End Sub 
Thanks for the quick response.

I am having a similar problem, however, I don't have a button named submit in my page.  There must be another cause to the Error parsing near 'BEGIN:VCALENDAR VER...' error.

I am using Outlook 2003.  The Export link works great from your demo site.
