Public ReadOnly Property DateTimePeriods As DateTimePeriodCollection

Property Value

Type	Description
DateTimePeriodCollection	A DateTimePeriodCollection object that is a collection of date-time periods.

Example

The following code snippet adds Quick Filters to the Date Filter dashboard item. It uses the DateTimePeriod static methods to create a predefined period. To create a custom period it creates the DateTimePeriod class instance and specify its settings as follows:

• Range. Create the FixedDateTimePeriodLimit or FlowDateTimePeriodLimit class objects and assign them to the DateTimePeriod.Start and DateTimePeriod.End properties.

  Note

  If you do not specify DateTimePeriod.Start/DateTimePeriod.End, the selection will begin from the start/end of the visible range.

• Name (quick filter’s caption). Assign a string to the DateTimePeriod.Name property.

C#

dateFilter.DateTimePeriods.AddRange(
    DateTimePeriod.CreateLastYear(),
    DateTimePeriod.CreateNextDays("Next 7 Days", 7),
    new DateTimePeriod
    {
        Name = DashboardWinLocalizer.GetString(DashboardWinStringId.PeriodMonthToDate),
        Start = new FlowDateTimePeriodLimit
        {
            Interval = DateTimeInterval.Month,
            Offset = 0
        },
        End = new FlowDateTimePeriodLimit
        {
            Interval = DateTimeInterval.Day,
            Offset = 1
        }
    },
    new DateTimePeriod
    {
        Name = "Jul-18-2018 - Jan-18-2019",
        Start = new FixedDateTimePeriodLimit
        {
            Date = new DateTime(2018, 7, 18)
        },
        End = new FixedDateTimePeriodLimit
        {
            Date = new DateTime(2019, 1, 18)
        }
    }
);

dateFilter.DateTimePeriods.AddRange(
    DateTimePeriod.CreateLastYear(),

    New DateTimePeriod With {
    .Name = DashboardWinLocalizer.GetString(DashboardWinStringId.PeriodMonthToDate),
    .Start = New FlowDateTimePeriodLimit With {.Interval = DateTimeInterval.Month, .Offset = 0},
    .End = New FlowDateTimePeriodLimit With {.Interval = DateTimeInterval.Day, .Offset = 1}
},
New DateTimePeriod With {
    .Name = "Jul-18-2018 - Jan-18-2019",
    .Start = New FixedDateTimePeriodLimit With {.Date = New Date(2018, 7, 18)},
