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:

Example 1

• C#
• VB.NET

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 

Using the above class we can now create sample data.

Example 2

• C#

public MainWindow() 
{ 
    InitializeComponent(); 
    this.DataContext = new List<TestData>() 
    { 
        new TestData { Category = "A", Subcategory = "100", Value = 10 }, 
        new TestData { Category = "B", Subcategory = "100", Value = 25 }, 
        new TestData { Category = "C", Subcategory = "200", Value = 40 }, 
        new TestData { Category = "D", Subcategory = "200", Value = 15 }, 
        new TestData { Category = "E", Subcategory = "200", Value = 30 }, 
    }; 
} 

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. We can also change the color of the groups using Colorizer.

Example 3

• XAML

<Window.Resources> 
    <telerik:PaletteBrushes x:Key="PivotMapBrushes"> 
        <SolidColorBrush Color="#69C7D3" /> 
        <SolidColorBrush Color="#B1E292" /> 
        <SolidColorBrush Color="#D2B4E2" /> 
        <SolidColorBrush Color="#A2D7F0" /> 
        <SolidColorBrush Color="#E8D982" /> 
        <SolidColorBrush Color="#BBDBC6" /> 
        <SolidColorBrush Color="#B0BADB" /> 
    </telerik:PaletteBrushes>         
</Window.Resources> 
<telerik:RadPivotMap Name="treeMap1"  
                        ValuePath="Value"  
                        ItemsSource="{Binding}"> 
    <telerik:RadPivotMap.GroupDefinitions> 
        <telerik:GroupDefinition Member="Category"> 
            <telerik:GroupDefinition.Mappings> 
                <telerik:PaletteColorizer Brushes="{StaticResource PivotMapBrushes}" /> 
            </telerik:GroupDefinition.Mappings>                
        </telerik:GroupDefinition> 
        <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.
