I made a custom Sharepoint 2010 list and then made a Calendar view for the list. When I view the calender, however, I don't get a link to add a new entry on the calendar like I do for the default calendar. I saw this suggestion but I don't know how to change the type. I am only using Sharepoint Designer. What should I do?
You have created a Calendar View in an existing list which was not created from Calendar List template. So the new option is not available. New option is available as usual from the Items Tab.
The link that you referred started with events list template so he gets the link to add new event in a calendar.
