Constructors

ChartNode()

Initializes a new instance of the ChartNode class.

protected ChartNode()

Properties

CollectionIndex

int

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.

[Browsable(false)]
public int CollectionIndex { get; }

Index

int

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

[Browsable(false)]
public int Index { get; }

IsArrangeValid

bool

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

[Browsable(false)]
public bool IsArrangeValid { get; }

IsTreeLoaded

bool

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

[Browsable(false)]
public virtual bool IsTreeLoaded { get; }

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

RadRect

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

[Browsable(false)]
public RadRect LayoutSlot { get; }

NodeState

Gets the current state of the node.

[Browsable(false)]
public NodeState NodeState { get; }

Parent

ChartElement

Gets the ChartElement where this node resides.

[Browsable(false)]
public ChartElement Parent { get; }

Presenter

IChartElementPresenter

Gets the IChartElementPresenter instance where this node is visualized.

[Browsable(false)]
public virtual IChartElementPresenter Presenter { get; }

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

Parameters:rectRadRectshouldRoundLayoutboolReturns:
