ExpandedClusterAdaptiveLayout Class
A layout algorithm that positions clustered items based on their count in the cluster.
Namespace: DevExpress.XtraMap
Assembly: DevExpress.XtraMap.v25.1.dll
NuGet Package: DevExpress.Win.Map
Declaration
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:
MouseHoverInteractiveClusterMode interactiveMode = new MouseHoverInteractiveClusterMode();
interactiveMode.ExpandedClusterLayout = new ExpandedClusterAdaptiveLayout();
map.InteractiveClusterMode = interactiveMode;
