ExpandedClusterAdaptiveLayout Class

A layout algorithm that positions clustered items based on their count in the cluster.

Assembly : DevExpress.XtraMap.v25.2.dll

Declaration

C#
VB.NET

csharp

public class ExpandedClusterAdaptiveLayout :
    ExpandedClusterLayoutBase

Public Class ExpandedClusterAdaptiveLayout
    Inherits ExpandedClusterLayoutBase

Remarks

A user can hover over a cluster to expand it. For more information on how expand clusters, refer to the following section: Allow Users to Expand Clusters.

When the cluster is expanded, nested items that form this cluster are positioned on the map according to a specified layout. To use an adaptive layout, assign an ExpandedClusterAdaptiveLayout object to the InteractiveClusterModeBase.ExpandedClusterLayout property. In the adaptive layout, the map control displays items in a spiral if a cluster contains more than 8 items. Otherwise, items are positioned in a circle.

You can override the GetLocation method to obtain the location of a specific item after the parent cluster is expanded.

Example

The following code allows users to expand clusters. The ExpandedClusterAdaptiveLayout applies to clustered items:

C#
VB.NET

csharp

MouseHoverInteractiveClusterMode interactiveMode = new MouseHoverInteractiveClusterMode();
interactiveMode.ExpandedClusterLayout = new ExpandedClusterAdaptiveLayout();
map.InteractiveClusterMode = interactiveMode;

Dim interactiveMode As MouseHoverInteractiveClusterMode = New MouseHoverInteractiveClusterMode()
interactiveMode.ExpandedClusterLayout = New ExpandedClusterAdaptiveLayout()
map.InteractiveClusterMode = interactiveMode
