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.

   C#

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

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

   XAML

   	<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.
