DayView.Days Property

Gets or sets the days displayed in the DayView.

Namespace: DevExpress.Xpf.Scheduling

Assembly: DevExpress.Xpf.Scheduling.v23.2.dll

NuGet Package: DevExpress.Wpf.Scheduling

Declaration

C#

public IEnumerable<DateTime> Days { get; set; }

VB.NET

Public Property Days As IEnumerable(Of Date)

Property Value

Type	Description
IEnumerable<DateTime>	An IEnumerable<T><DateTime,> list of dates displayed in a view.

Remarks

The Days property allows you to specify non-consecutive dates to display in the DayView. In an application with a DateNavigator control it allows you to obtain a list of days selected by the end-user.

Note

Navigating the scheduler changes the Days list to a contiguous sequence of dates.

Example

This example implements a custom KeyToCommand behavior to handle Day View navigation. The view displays seven days, Saturday and Sunday excluded. A custom set of days is assigned to the DayView.Days property.

View Example

MainWindow.xaml

<dxmvvm:Interaction.Behaviors>
    <dxmvvm:KeyToCommand Command="{DXCommand Execute='MyMoveLeft(@e(scheduler))'}" KeyGesture="Left" />
    <dxmvvm:KeyToCommand Command="{DXCommand Execute='MyMoveRight(@e(scheduler))'}" KeyGesture="Right" />
</dxmvvm:Interaction.Behaviors>

MainViewModel.cs

public void MyMoveLeft(SchedulerControl scheduler)
{
    MyMove(false, scheduler);
}
public void MyMoveRight(SchedulerControl scheduler)
{
    MyMove(true, scheduler);
}
public void MyMove(bool forward, SchedulerControl scheduler)
{
    if (SchedulerStart.Date == scheduler.Start.Date) return;
    FixVisibleDays(forward, scheduler);
    SchedulerStart = scheduler.Start;
}
private void FixVisibleDays(bool forward, SchedulerControl scheduler)
{
    DayView myView = scheduler.ActiveView as DayView;
    DateTime startDate = scheduler.Start;
    if (myView != null)
    {
        DateTimeRange selection = scheduler.SelectedInterval;
        startDate = CorrectDate(startDate, forward);
        List<DateTime> visibleDays = GetDays(startDate);
        // Specify DayView's visible days 
        myView.Days = visibleDays;
        scheduler.SelectedInterval = AdjustSelection(forward, selection);
    }
}
