C# system windows forms calendar

In that event, you should manage to bring information to display in the calendar, by adding items to the Items collection of the calendar.

The event is raised every time the view changes. I strongly suggest that you use caching and not query the database every time this event is raised, because performance will be severely affected. I strongly suggest to add items that only intersect with the calendar's view range. You can learn how to check date intersection by taking a look at the implementation of DateIntersects , in Calendar :. Since you can explore other members using IntelliSense I list events here; they are important because they let you control your application of the Calendar.

When items intersect in their date ranges, there's a nice algorithm that performs a layout to accommodate them. Give it a try.

Example 5. File: ConfigureSchedule. Substring item. Substring 0, name. LastIndexOf ". ScheduledItemStartDate, item. Add ci ; calendar1. Example 6. Show "Item already exists. OK, MessageBoxIcon. Date, calendar1. Add csi. Example 7. File: FirstView. Add new ItemInfo item. StartTime, item. EndTime, item. Firstname, item. Surname, item. Example 8. File: Calendar. Bounds; foreach Rectangle bounds in item.

ProjectId; calendarItem. MonthCalendar has several properties related to bolded dates. In the MonthCalendar, some dates can be bolded to indicate an important event. Next We look at a code example that demonstrates setting the BoldedDates property.

MaxDate, MinDate. These indicate the maximum and minimum selectable dates. These dates give you a lot of range to select dates. C program that uses MonthCalendar and BoldedDates. Color properties. Another set of properties you can edit on the MonthCalendar are the color properties.
