SchedulerControl.SelectedInterval Property

Gets or sets the time interval currently selected by an end-user. This is a dependency property.

Namespace: DevExpress.Xpf.Scheduling

Assembly: DevExpress.Xpf.Scheduling.v18.2.dll

Declaration

C#

public DateTimeRange SelectedInterval { get; set; }

VB.NET

Public Property SelectedInterval As DateTimeRange

Property Value

Type	Description
DateTimeRange	A DateTimeRange object that is the selected time interval.

Remarks

Use SelectedInterval to retrieve the time interval selected by an end-user. If the appointment is selected, the SelectedInterval property returns the time interval this appointment occupies. Use the SchedulerControl.SelectedResource property to access the resource related to the selected time interval.

To determine the selection change, subscribe to the SchedulerControlBase.DependencyPropertyChanged event, as illustrated in the following code snippet.

Note

The complete sample project How to obtain the appointment, resource or time interval selected by an end-user is available in the DevExpress Examples repository.

C#

private void schedulerControl_DependencyPropertyChanged(object sender, DependencyPropertyChangedEventArgs e)
{
    SchedulerControl scheduler = sender as SchedulerControl;
    if (e.Property == SchedulerControl.SelectedIntervalProperty)
    {
        OutputBox.AppendText(string.Format("SelectedInterval is changed. New value is {0} \r\n", e.NewValue));
        OutputBox.ScrollToEnd();
    }
    if (e.Property == SchedulerControl.SelectedResourceProperty)
    {
        OutputBox.AppendText(string.Format("SelectedResource is changed. New value is {0} \r\n", ((ResourceItem)e.NewValue).Caption));
        OutputBox.ScrollToEnd();
    }
}

VB.NET

Private Sub schedulerControl_DependencyPropertyChanged(ByVal sender As Object, ByVal e As DependencyPropertyChangedEventArgs)
    Dim scheduler As SchedulerControl = TryCast(sender, SchedulerControl)
    If e.Property = SchedulerControl.SelectedIntervalProperty Then
        OutputBox.AppendText(String.Format("SelectedInterval is changed. New value is {0} " & ControlChars.CrLf, e.NewValue))
        OutputBox.ScrollToEnd()
    End If
    If e.Property = SchedulerControl.SelectedResourceProperty Then
        OutputBox.AppendText(String.Format("SelectedResource is changed. New value is {0} " & ControlChars.CrLf, CType(e.NewValue, ResourceItem).Caption))
        OutputBox.ScrollToEnd()
    End If
End Sub
