ExpandedClusterSourceLocationLayout Class

A layout algorithm that positions clustered items according to their actual locations (cartesian or geo coordinates).

Namespace: DevExpress.XtraMap

Assembly: DevExpress.XtraMap.v21.2.dll

Declaration

public class ExpandedClusterSourceLocationLayout :
    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 position clustered items according to their actual coordinates (cartesian or geo), assign an ExpandedClusterSourceLocationLayout object to the InteractiveClusterModeBase.ExpandedClusterLayout property.

ExpandedCluster - Source Location Based Layout

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 ExpandedClusterSourceLocationLayout applies to clustered items:

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