API Changes

Removed delegates

Delegate types that used to define events have been removed. Events are now defined using the generic EventHandler delegate with the respective EventArgs-derived type as argument. For example, NodeCreated is now defined as follows:

C#

public event EventHandler<NodeEventArgs> NodeCreated;

The follow list shows all delegate types that have been removed:

• ControlNodeEventHandler
• CopyHostedControlEventHandler
• InPlaceEditEventHandler
• PaintControlEventHandler
• AnchorPointEventHandler
• AreaEventHandler
• CellEventHandler
• CellValidationEventHandler
• ClipboardEventHandler
• ContainerChildEventHandler
• DiagramEventHandler
• DrawAnchorPointEventHandler
• DrawCellEventHandler
• DrawItemEventHandler
• DrawLinkEventHandler
• DrawNodeEventHandler
• EditCellTextEventHandler
• EditLinkTextEventHandler
• EditNodeTextEventHandler
• GroupEventHandler
• HitTestEventHandler
• InstantiateItemEventHandler
• ItemEventHandler
• LinkEventHandler
• LinkValidationEventHandler
• NodeEventHandler
• NodeValidationEventHandler
• RepaintEventHandler
• RowEventHandler
• SerializeTagEventHandler
• ShapeEventHandler
• TimerEventHandler
• TreeItemEventHandler
• TreeItemValidationEventHandler
• UndoEventHandler
• UndoValidationEventHandler
• ValidationEventHandler

Removed delegates in the MindFusion.Diagramming.Import namespace:

• ConnectorImportedEventHandler
• GroupImportedEventHandler
• ShapeImportedEventHandler

Removed delegates in the MindFusion.Diagramming.Lanes namespace:

• CellBoundsEventHandler

Renamed types and members

The following table lists the renamed types.

Old name	New name
LinkStyle	LinkShape
TableStyle	SimpleShape
GroupImportedArgs	GroupImportedEventArgs

The following types were moved from the MindFusion.Diagramming.Components to the MindFusion.Diagramming namespace:

• NotifyCollectionChangedAction
• NotifyCollectionChangedEventArgs
• ObservableCollection

The following table lists the renamed members.

Old name (old type)	New name (new type)
Diagram.TableStyle (TableStyle)	Diagram.TableShape (SimpleShape)
Diagram.LinkStyle (LinkStyle)	Diagram.LinkShape (LinkShape)
DiagramLink.Style (LinkStyle)	DiagramLink.Shape (LinkShape)
TableNode.Style (TableStyle)	TableNode.Shape (SimpleShape)
TreeViewItem.LabelColor (Color)	TreeViewItem.LabelBrush (Brush)
ContainerNode.CaptionColor (Color)	ContainerNode.CaptionBrush (Brush)
TableNode.CaptionColor (Color)	TableNode.CaptionBrush (Brush)
DiagramItem.TextColor (Color)	DiagramItem.TextBrush (Brush)
DiagramItem.ShadowColor (Color)	DiagramItem.ShadowBrush (Brush)

The z-order related methods in the DiagramItem class now also accept a single boolean argument.

Collections

Several collections have been converted to generic types. The table below provides an overview of this change.

Old signature	New signature
ItemCollectionBase	ItemCollectionBase<T>
PersistableCollection	PersistableCollection<T>
ReadOnlyCollection	ReadOnlyCollection<T>

In addition the collection classes no longer implement IList and ICollection. Calls that expect those interfaces will result in compilation errors. The collection classes also do not expose the Capacity property.
