SchedulerStorage.PrepareAppointmentFilterColumn Event

Fires when a column, representing an appointment's field, is added to the collection of filter columns contained within the FilterControl.

Namespace:DevExpress.XtraScheduler
Assembly:DevExpress.XtraScheduler.v17.2.dll

Expanded Syntax

Expanded Event Data

The event handler receives an argument of type PrepareFilterColumnEventArgs containing data related to this event.

The following PrepareFilterColumnEventArgs properties provide information specific to this event.
Property Description
Cancel Gets or sets a value indicating whether the event should be canceled.
FilterColumn Gets or sets a field to which a filter criteria is applied.

Expanded Remarks

You can use the FilterControl to display only appointments that meet the specified conditions. To enable the control to filter appointments contained within the SchedulerStorage, the FilterControl.SourceControl property should be set to the Appointments collection.

When the FilterControl begins creating a collection of columns which will be used to construct a logical expression (available via the FilterControl.FilterString property), the PrepareAppointmentFilterColumn event is raised for each added column. Handling this event enables you to substitute the column's name with a custom text, or prepare a custom editor for specific value types. The column being added is available via the FilterColumn property of the event handler's parameter.

The following code snippet illustrates the use of PrepareAppointmentFilterColumn event:
