Namespace: DevExpress.Xpf.Scheduling

Assembly: DevExpress.Xpf.Scheduling.v25.1.dll

NuGet Package: DevExpress.Wpf.Scheduling

Declaration

C#

public CriteriaOperator AppointmentFilterCriteria { get; set; }

VB.NET

Public Property AppointmentFilterCriteria As CriteriaOperator

Property Value

Type	Description
CriteriaOperator	A DevExpress.Data.Filtering.CriteriaOperator object which represents filter criteria.

Remarks

Use the FilterAppointment event to override the filter criteria. The event’s Visible property returns false for appointments filtered by the AppointmentFilterCriteria or AppointmentFilterString property.

The example below shows how to set a filter criteria.

C#

  scheduler.AppointmentFilterCriteria = GroupOperator.Combine(GroupOperatorType.Or, new BinaryOperator("LabelId", 1, BinaryOperatorType.Equal),
    new BinaryOperator("LabelId", 2, BinaryOperatorType.Equal));

VB.NET

  scheduler.AppointmentFilterCriteria = GroupOperator.Combine(GroupOperatorType.Or, New BinaryOperator("LabelId", 1, BinaryOperatorType.Equal),
    New BinaryOperator("LabelId", 2, BinaryOperatorType.Equal))

The following example shows how to set the same filter criteria by parsing a filter string.

C#

 scheduler.AppointmentFilterCriteria = CriteriaOperator.Parse("[LabelId] In (1, 2)");

VB.NET

 scheduler.AppointmentFilterCriteria = CriteriaOperator.Parse("[LabelId] In (1, 2)")
