Add an iCal feed to Sitefinity

{:target=”_blank”}feeds let you share your and/or import your events that are stored in Sitefinity. Here is a library that will let you generate an iCal feed from Sitefinity. Future versions of this library might have us filtering by categories or date.

iCal feed for Sitefinity CalendarHandler_2

I’ve made a few changes since the last release to include some bug fixes.

• Added Google and Outlook friendly fields in the feed file to describe the iCalendar file as well as the publisher.
• Added code to the Location and Description fields to keep them at 75 characters or less to comply with the iCal specifications.

Installation

web.config changes

First, you need to tell ASP.NET about your new handler. Open up the web config file and look for the httpHandlers section, it’s the parent is system.web and add the following:

<add verb="GET" path="GetICSFile.ashx" type="SEVDNUG.Web.HttpHandlers.CalendarHandler, App_Code"/>

Note: The path name can be changed to any legal value like feeds/ical.ashx or ical.ashx.

Files

Copy the vCalendar.cs and CalendarHandler.cs files to the App_Code directory of your Sitefinity installation.

Customize

Getting the event data from Sitefinity and creating the iCalender objects is handled inside the CalendarHandler class.

The class assumes that your events provider is named Events, if not you will have to change line 25 of the class.

The class maps the following fields to an iCalendar event.

iCalendar event	Sitefinity Field
Description	Content
Location	LocationName (Meta Field)
Summary	Title (Meta field)
Url	UrlWithExtension
DTStart	Start
DTEnd	End

I believe these meta values are the default meta keys from Sitefinity. If your values differ, you can modify them on lines 64 and 65.
