 | AddHandler | (Inherited from System.Windows.UIElement) |

| CanStart | Overridden. This tool can run if this diagram allows selection and moves/copies/dragging-out, if the mouse has moved far enough away to be a drag and not a click, and if FindDraggablePart has found a selectable part at the mouse-down point. |
| ClearValue | (Inherited from System.Windows.DependencyObject) |
| ComputeEffectiveCollection | Find the actual collection of nodes and links to be moved or copied, given an initial collection. |
| DoActivate | Overridden. Start the dragging operation. |
| DoCancel | Overridden. Abort any dragging operation. |
| DoDeactivate | This method is called by the diagram on the old tool when Northwoods.GoXam.Diagram.CurrentTool is set to a new tool. (Inherited from Northwoods.GoXam.Tool.DiagramTool) |
| DoKeyDown | Overridden. Handle switching between copying and moving modes as the Control key is pressed or released. |
| DoKeyUp | Overridden. Handle switching between copying and moving modes as the Control key is pressed or released. |
| DoMouseDown | The diagram will call this method upon a mouse down event. (Inherited from Northwoods.GoXam.Tool.DiagramTool) |
| DoMouseMove | Overridden. As the user moves the mouse, move the collection of CopiedParts or DraggedParts, depending on whether MayCopy or MayMove is true. |
| DoMouseUp | Overridden. On a mouse-up finish moving or copying the effective selection. |
| DoMouseWheel | The diagram will call this method as the mouse wheel is rotated. (Inherited from Northwoods.GoXam.Tool.DiagramTool) |
