Namespace: DevExpress.DashboardCommon

Assembly: DevExpress.Dashboard.v24.2.Core.dll

Declaration

C#

public class RangeFilterDashboardItem :
    SeriesDashboardItem,
    IArgumentsDashboardItem,
    IDateTimePeriodContext,
    ISupportDateTimePeriods

VB.NET

Public Class RangeFilterDashboardItem
    Inherits SeriesDashboardItem
    Implements IArgumentsDashboardItem,
               IDateTimePeriodContext,
               ISupportDateTimePeriods

Remarks

The Range Filter allows end-users to apply filtering to other dashboard items. It displays a chart with selection thumbs above that allow you to filter out values displayed along the argument axis.

You can use the Date Filter dashboard item as the Range Filter’s compact counterpart.

The following documentation is available.

• WinForms Designer - Creating a Range Filter
• Web Dashboard - Creating a Range Filter

Note

The Range Filter dashboard item cannot be bound to the OLAP data source.
