Description

How to show clustering bubble for single item in RadMap.

Solution

1. Create a class inheriting DefaultClusterGenerator and set its AutoExpandWhenSingle property to False.

       public class CustomClusterGenerator : DefaultClusterGenerator 
       { 
           public CustomClusterGenerator() 
           { 
               this.AutoExpandWhenSingle = false; 
           } 
       } 
   

2. Set the CustomClusterGenerator to the ClusterGenerator property of the RadMap.

       <telerik:RadMap > 
           <telerik:RadMap.Resources> 
               <local:CustomClusterGenerator x:Key="CustomClusterGenerator" /> 
           </telerik:RadMap.Resources> 
           <telerik:VisualizationLayer ClusteringEnabled="True" 
                                       ClusterGenerator="{StaticResource CustomClusterGenerator}"> 
           </telerik:VisualizationLayer> 
       </telerik:RadMap> 
   

   The namespace "local" refers to the namespace, where the "CustomClusterGenerator" class is defined.
