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.
