DashboardLayoutGroup Class

A layout group used to arrange layout items or other groups within a dashboard.

Namespace: DevExpress.DashboardCommon

Assembly: DevExpress.Dashboard.v18.2.Core.dll


public class DashboardLayoutGroup :
Public Class DashboardLayoutGroup
    Inherits DashboardLayoutNode


The DashboardLayoutGroup class exposes the DashboardLayoutGroup.ChildNodes property that provides access to the collection of child layout groups and items that constitute the current layout group. Use the DashboardLayoutGroup.Orientation property to specify the orientation of layout items/groups within the group.

The DashboardLayoutGroup.Weight property allows specifying the relative size of the layout group.


The following example demonstrates how to modify dashboard layout in code.

In this example, the DashboardViewer loads a dashboard containing three dashboard items placed vertically, one above the other. The following steps are taken to create a new layout:

  • Three DashboardLayoutItem objects are created to display the existing dashboard items. The weight parameter specifies the layout item's relative size.
  • A new DashboardLayoutGroup is created to display two dashboard items. The Orientation parameter specifies how layout items are placed within the group.
  • A root layout group is created. This group contains the previously created group and another layout item.
  • The root layout group is assigned to the LayoutRoot property.

This example also demonstrates how to swap layout items using the MoveRight(DashboardLayoutNode) method, save and restore the layout using the SaveDashboardLayout(String) and LoadDashboardLayout(String) methods.
