C# UWP/WinRT Google Calendar: Change the Color of an Event

Back to Index

Changes the color of a particular event. The calendar and event are specified by ID. This example changes the color for an event (id = 52e7uk7j7vl5dosj7b25memov0) on the calendar (id = support@chilkatcloud.com).
This changes the event to colorId = "6" which seems to be an orange-ish color..
