Calendar panels


A Calendar panel

Calendar Panels populate a calendar with information from a data source, making use of three unique control types: Description, Event Start, and Event End. The Description control designates what will appear on the calendar, and is typically an event name. The Event Start and Event End controls designate which day the event will appear on, and may include timestamps, which will be displayed alongside the event description. Like with Chart Panels, Calendar Panels can be linked to another Panel in order to display greater detail regarding the event on the calendar.

By default, the Calendar Panel will display based upon the data in the Business Rule, honoring whatever sort is applied in the Business Rule. Review your Business Rule to verify the sort.

If there is no data in the Business Rule, then the current month, day or year should appear on the Calendar. As soon as data is added you'll likely want to add a sort to the Business Rule.

How to display current month on calendar

To make sure the panel returns the current month, day or year, add a column called Sort with logical type numeric and apply a sort ascending on this column. For example if your business object supporting your calendar panel has a column called StartDate that you'd like to use and it's a SQL datasource you can use a sql escape function:

${ABS(DateDiff(day, getdate(), StartDate))}

or a Vinyl IIF statement:

IIF(DateDiff(dd, Now(), StartDate) < 0, (DateDiff(dd, Now(), StartDate))*-1, DateDiff(dd, Now(), StartDate))


The SQL escape method is more programatically efficient but IIF doesn't rely on SQL syntax. Both result with identical output.

To view other months, click on the forwards and backwards chevron buttons in the upper left-hand corner of the panel. Toggling between Day, Week, and Monthly views can be done by clicking on the corresponding buttons in the upper right-hand corner of the panel. Calendar panels cannot be edited; however, a separate panel that displays the event controls can be.
