The actual size of the item.
protected virtual Size ActualSize { get; }Gets or sets the preferred location of the element if its size is less than its parent size.
[Browsable(false)]
public override ContentAlignment Alignment { get; set; }Overrides:
Gets or sets a value indicating whether copying is allowed.
public bool AllowCopy { get; set; }True if copying is allowed; otherwise, false.
Implements:
Gets or sets a value indicating whether cutting is allowed.
public bool AllowCut { get; set; }True if cutting is allowed; otherwise, false.
Implements:
Gets or sets a value indicating whether deleting is allowed.
public bool AllowDelete { get; set; }True if deleting is allowed; otherwise, false.
Implements:
Gets or sets a value indicating whether pasting is allowed.
public bool AllowPaste { get; set; }True if pasting is allowed; otherwise, false.
Implements:
Gets or sets the rotation transform angle used when painting the element and its children.
[Browsable(false)]
public override float AngleTransform { get; set; }Overrides:
Gets the bounds.
[Browsable(false)]
public virtual Rect Bounds { get; }The bounds.
Implements:
Gets or sets the content.
[Browsable(false)]
public object Content { get; set; }Implements:
The property matches the ContentControl.Content property.
public object DataBoundItem { get; set; }Gets the owning diagram of this instance.
protected IGraphInternal Diagram { get; }Gets the unique identifier of this entity.
public string Id { get; }An identifier for this entity.
Implements:
Gets or sets a value indicating whether manipulation on the connectors is enabled.
public bool IsConnectorsManipulationEnabled { get; set; }True if manipulation on connectors is enabled; otherwise, false.
Implements:
Gets or sets a value indicating whether dragging is enabled.
public bool IsDraggingEnabled { get; set; }True if dragging is enabled; otherwise, false.
Implements:
Gets or sets whether this item is dynamically generated.
[Browsable(false)]
public bool IsDynamic { get; set; }If true then this item will not be serialized as part of the diagram.
Implements:
In some applications or embeddings of RadDiagram (e.g. workflows) there are shapes or connections
which are generated as part of some layout or organization. In those cases it doesn't make sense to serialize
the elements which are automatically generated as part of the application. By setting this property to true the serialization pipeline will omit the element.
Gets or sets a value indicating whether editing is enabled on this item.
public bool IsEditable { get; set; }True if editing is enabled; otherwise, false.
Implements:
Note that the similar higher-level IsEditable can potentially overrule this setting.
Gets or sets whether the diagram entity is enabled.
public virtual bool IsEnabled { get; set; }True if enabled; otherwise, false.
Implements:
Gets or sets a value indicating whether this instance is in edit mode.
public bool IsInEditMode { get; set; }True if this instance is in edit mode; otherwise, false.
Implements:
Gets or sets a value indicating whether the manipulation adorner is visible.
public bool IsManipulationAdornerVisible { get; set; }True if the manipulation adorner is visible; otherwise, false.
Implements:
Gets or sets a value indicating whether resizing is enabled.
public bool IsResizingEnabled { get; set; }True if resizing is enabled; otherwise, false.
Implements:
Gets or sets a value indicating whether rotation is enabled.
public bool IsRotationEnabled { get; set; }true if this rotation is enabled; otherwise, false.
Implements:
Gets or sets whether the diagram entity is selected.
public bool IsSelected { get; set; }True if selected; otherwise, false.
Implements:
Gets a value indicating whether this instance is selected in group.
protected bool IsSelectedInGroup { get; set; }True if this item is selected in group; otherwise, false.
Gets whether any service is manipulating at the moment.
protected bool IsServiceManipulation { get; }ParentContainer
[Browsable(false)]
public IContainerShape ParentContainer { get; }Implements:
Gets or sets the group.
[Browsable(false)]
public IGroup ParentGroup { get; set; }The group.
Implements:
Gets or sets the position of the top left corner of the bounding rectangle of the item.
public Point Position { get; set; }Implements:
Gets or sets the direction of flow of the elements and whether elements are aligned to support locales using right-to-left fonts.
[Browsable(false)]
public override bool RightToLeft { get; set; }Overrides:
Gets the service locator.
protected IGraphServiceLocator ServiceLocator { get; }[Browsable(false)]
public override bool StretchHorizontally { get; set; }Overrides:
[Browsable(false)]

Methods
protected virtual void CallBeginEditEvent()protected virtual void CustomizeTextBoxEditor()Deserializes the serialization info in this diagram entity.
public virtual void Deserialize(SerializationInfo info)A SerializationInfo instance.
Implements:
Initializes the specified service locator and parent graph.
protected virtual void Initialize(IGraphServiceLocator serviceLocator, IGraphInternal graph)The service locator.
graphIGraphInternalThe diagram control.
protected virtual void InitializeGlobalSettingsFromDiagram(RadDiagramElement diagramParent)When overridden in a derived class, is invoked whenever application code or internal processes (such as a rebuilding layout pass) call . In simplest terms, this means the method is called just before a UI element displays in an application. For more information, see Remarks.
