Task.cs

// Developer Express Code Central Example:
// Printing appointment details using the XtraReports Suite
// 
// This example illustrates how you can print the appointment details for the
// appointments currently displayed in the Scheduler by means of the XtraReports
// Suite.
// The key point is to obtain a collection of appointments and assign it to
// the report's DataSource
// (http://documentation.devexpress.com/#XtraReports/DevExpressXtraReportsUIXtraReportBase_DataSourcetopic).
// To accomplish this, the GetAppointments
// (http://documentation.devexpress.com/#WindowsForms/DevExpressXtraSchedulerSchedulerStorageBase_GetAppointmentstopic)
// method is used to get a collection of appointments which fall within the time
// range specified by the GetVisibleIntervals
// (http://documentation.devexpress.com/#WindowsForms/DevExpressXtraSchedulerSchedulerViewBase_GetVisibleIntervalstopic)
// method.
// To display custom fields in the report, the custom fields
// (http://documentation.devexpress.com/#WindowsForms/clsDevExpressXtraSchedulerNativeCustomFieldtopic)
// should be exposed as common object properties. So a wrapper class Task is
// implemented solely for this purpose. Using the SetAppointmentFactory
// (http://documentation.devexpress.com/#WindowsForms/DevExpressXtraSchedulerAppointmentStorageBase_SetAppointmentFactorytopic)
// method, Scheduler's Appointment objects are replaced with the Task class
// instances. A TaskCollection class holds Task objects and can be used as the
// report's data source.
// Note that you should have a valid license to the
// XtraReports Suite
// (http://documentation.devexpress.com/#XtraReports/CustomDocument2162) to be able
// to use this approach in your application.
// 
// You can find sample updates and versions for different programming languages here:
