Syntax

public abstract class ChartNode : PropertyBagObject, IDisposable, INotifyPropertyChanged

Constructors

ChartNode()

Initializes a new instance of the ChartNode class.

Declaration
protected ChartNode()

Properties

CollectionIndex

Gets the index of this node in its owning typed collection. An AxisLabelModel for example will have this property set to the index of the label within the Labels collection.

Declaration
public int CollectionIndex { get; }
Property Value
System.Int32

Index

Gets the index of this node in its parent ChartElement nodes collection.

Declaration
public int Index { get; }
Property Value
System.Int32

IsArrangeValid

Gets a value indicating whether the node is laid-out on the chart scene.

Declaration
public bool IsArrangeValid { get; }
Property Value
System.Boolean

IsTreeLoaded

Gets a value indicating whether the logical tree this node is part of is loaded.

Declaration
public virtual bool IsTreeLoaded { get; }
Property Value
System.Boolean

Remarks

This actually checks for a valid ChartAreaModel reference and asks whether the area itself is loaded. This value may differ from the current NodeState.

LayoutSlot

Gets the rectangle (in physical coordinates) where this node resides.

Declaration
public RadRect LayoutSlot { get; }
Property Value
RadRect

NodeState

Gets the current state of the node.

Declaration
public NodeState NodeState { get; }
Property Value
NodeState

Parent

Gets the ChartElement where this node resides.

Declaration
public ChartElement Parent { get; }
Property Value
ChartElement

Presenter

Gets the IChartElementPresenter instance where this node is visualized.

Declaration
public virtual IChartElementPresenter Presenter { get; }
Property Value
IChartElementPresenter

Methods

Arrange(RadRect, Boolean)

Arranges the node within the specified layout slot.

Declaration
public RadRect Arrange(RadRect rect, bool shouldRoundLayout = true)
Parameters
RadRect rect

System.Boolean shouldRoundLayout

Returns
RadRect

ClearValueCore(Int32)

Declaration
public override bool ClearValueCore(int key)
Parameters
System.Int32 key

Returns
System.Boolean

Overrides

Invalidate()

Delegates an "Invalidate" request to the owning IChartView instance (if any).

Declaration
public virtual void Invalidate()

SetValueCore(Int32, Object)

Declaration
public override bool SetValueCore(int key, object value)
Parameters
System.Int32 key

System.Object value

Returns
System.Boolean

Overrides

Events
