Represents a group used to arrange dashboard items within a dashboard.

Namespace: DevExpress.DashboardCommon

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

Declaration

C#

public class DashboardItemGroup :
    DashboardItem,
    IMasterFilterItem,
    IInteractivityOptionsProvider,
    IDashboardItemContainer

VB.NET

Public Class DashboardItemGroup
    Inherits DashboardItem
    Implements IMasterFilterItem,
               IInteractivityOptionsProvider,
               IDashboardItemContainer

Related API Members

The following members return DashboardItemGroup objects:

• Dashboard.CreateGroup()
• DashboardItem.Group
• DashboardItemGroup.Group

Remarks

A dashboard item group arranges dashboard items within the dashboard into a separate layout group. Moreover, the dashboard item group provides the capability to manage interaction between dashboard items within and outside of the group.

To create and manage a dashboard item group in code, use the following members:

• To add a group to the dashboard, use the Dashboard.Groups property or create a new group using the Dashboard.CreateGroup method.
• To add or remove dashboard items to/from the group, use the Add/Remove methods. The Items property provides access to dashboard items contained within the current group.

• To access interactivity settings for the current DashboardItemGroup, use the InteractivityOptions property. The DashboardItemGroupInteractivityOptions object returned by this property exposes the following members.

  • The DashboardItemGroupInteractivityOptions.IsMasterFilter property provides the capability to filter external dashboard items using master filter items contained within the current dashboard item group. If this property is set to false, master filter items contained within the group can filter only dashboard items from this group.
  • The FilterableDashboardItemInteractivityOptions.IgnoreMasterFilters property allows you to isolate dashboard items contained within the group from being filtered using external master filter items.

Example

This example demonstrates how to combine filter elements in a group and bind them to data in code.

The dashboard contains the following filter items combined in a group:

• ComboBoxDashboardItem
• ListBoxDashboardItem
• TreeViewDashboardItem

The group serve as a master filter for the Chart dashboard item.
