Populating With Data RadPivotMap

RadPivotMap expects data in tabular format and displays a treemap with grouped data, according to the GroupDefinition-s set.

Assuming that you have the following class:

public class TestData 
{ 
     public int Value { get; set; } 
     public string Category { get; set; } 
     public string Subcategory { get; set; } 
} 

Private _category As String 
    Public Property Category() As String 
        Get 
            Return _Category 
        End Get 
        Set(ByVal value As String) 
            _Category = value 
        End Set 
    End Property 
Private _Value As Integer 
    Public Property Value() As Integer 
        Get 
            Return _Value 
        End Get 
        Set(ByVal value As Integer) 
            _Value = value 
        End Set 
    End Property 
Private _Subcategory As String 
    Public Property Subcategory() As String 
        Get 
            Return _subcategory 
        End Get 
        Set(ByVal value As String) 
            _Subcategory = value 
        End Set 
    End Property 

To bind the RadPivotMap you should use the GroupDefinition collection and add several GroupDefinitions - one for each of the properties as presented in the class. The ValuePath property specifies from where the data should be taken.

<telerik:RadPivotMap Name="treeMap1" ValuePath="Value"> 
    <telerik:RadPivotMap.GroupDefinitions> 
                    <telerik:GroupDefinition Member="Category" /> 
                    <telerik:GroupDefinition Member="SubCategory" /> 
    </telerik:RadPivotMap.GroupDefinitions> 
</telerik:RadPivotMap> 

You can bind the RadPivotMap to any source that implements one of the following interfaces:

• IEnumerable - supports simple iteration of a collection. See the MSDN article for more on IEnumerable.

• ICollection - extends IEnumerable and supports size, enumerator, and synchronization methods for collections.

• IList - extends ICollection and is the base class for lists.
