[ObfuscationAttribute(StripAfterObfuscation = false, Exclude = true, 
	ApplyToMembers = false)]

Remarks

This is a specialized CanvasControl that can hold, display, and edit an IGraph instance. It provides access to the Graph and Selection instances, as well as provides convenience methods for Undo()()()() and Redo()()()() operations, as well as Cut()()()(), Copy()()()(), and Paste()()()() operations. Additionally it provides convenience methods for exporting the graph to GraphML and importing a graph from GraphML.

This control comes with a number of additional default command bindings that work on the graph instance (see also view port related commands in CanvasControl):

  • ApplicationCommands.Cut
  • ApplicationCommands.Copy
  • ApplicationCommands.Paste
  • ApplicationCommands.Undo
  • ApplicationCommands.Redo
By default, these commands are enabled and bind to the respective methods implemented by this class.

The following commands are bound to methods implemented by this class, but are disabled by default:

  • ApplicationCommands.Open
  • ApplicationCommands.Save
  • ApplicationCommands.SaveAs
To enable these command, set the FileOperationsEnabled dependency property to trueTruetruetrue (True in Visual Basic).

In addition to that this class declares the following new RoutedUICommands.

The ZoomToCurrentItemCommand is enabled, if NavigationCommandsEnabled is trueTruetruetrue (True in Visual Basic). All of these commands can be removed from the CommandBindings collection if necessary.
