Constructors

SparkNode()

Initializes a new instance of the SparkNode class.

protected SparkNode()

Properties

CollectionIndex

int

Gets the index of this node in its owning typed collection.

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

Index

int

Gets the index of this node in its parent SparkElement 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 SparkAreaModel 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

SparkElement

Gets the SparkElement where this node resides.

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

Presenter

ISparkElementPresenter

Gets the ISparkElementPresenter instance where this node is visualized.

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

SparkArea

SparkAreaModel

Gets the spark area whre this node resides.

[Browsable(false)]
public SparkAreaModel SparkArea { get; }

Methods

Arrange(RadRect, bool)

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

Parameters:rectRadRectshouldRoundLayoutboolReturns:

RadRect

ClearValueCore(int)

public override bool ClearValueCore(int key)

Parameters:keyint

The property key to clear.

Returns:

bool

true if the value was cleared successfully; otherwise, false.

Invalidate()

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

public virtual void Invalidate()

SetValueCore(int, object)

Core implementation for setting a property value. Override to provide custom setting logic.

public override bool SetValueCore(int key, object value)

Parameters:keyint

The property key.

valueobject

The property value to set.

Returns:

bool

true if the value was set successfully; otherwise, false.

Overrides: PropertyBagObject.SetValueCore(int, object)
