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.
