Sometime we need to show schedule of some events on
website and allow user to download the calendar for outlook which user can save
in their local computer or allow them to directly open it in outlook.
The trick here is same to write the code for
downloading any file from response, only thing to remember is the calendar
content and content type “text/calendar”.
Here is the code
protected void Button2_Click(object sender, EventArgs e)
{
System.Text.StringBuilder
sbICSFile = new System.Text.StringBuilder();
DateTime dtNow = DateTime.Now;
sbICSFile.AppendLine("BEGIN:VCALENDAR");
sbICSFile.AppendLine("VERSION:2.0");
sbICSFile.AppendLine("PRODID:-//ICSTestCS/");
sbICSFile.AppendLine("BEGIN:VEVENT");
sbICSFile.AppendLine("DTSTART:20120515T110000Z");
sbICSFile.AppendLine("DTEND:20120515T113000Z");
sbICSFile.AppendLine("UID:1");
sbICSFile.AppendLine("DESCRIPTION:Test Desc");
sbICSFile.AppendLine("SUMMARY:calander");
sbICSFile.AppendLine("END:VEVENT");
sbICSFile.AppendLine("END:VCALENDAR");
Response.ContentType = "text/calendar";
Response.AddHeader("content-disposition", "attachment;
filename=CalendarEvent1.ics");
Response.Write(sbICSFile);
Response.Flush();
Response.End();
}
Please leave your comments
or share this code if it’s useful for you.
