nshape can create group shape,but if grouped,all shape can't to move.

or,Create a shape as a container,and create a child shape drag into this container , and can be moved

can see this demo: http://files.cnblogs.com/try/demo.swf

Out of the box, NShape has no shapes that behave exactly the same like the shapes shown in your demo video.
But you can rearrange grouped shapes:

• Select the group
• Click on the child shape you want to move
• The shape's handles are displayed and the outlines of the other shapes in the group become gray.
• Now, you can move the child shape

If you want to implement the shown behavior yourself, you have to write your own container shape:

• Derive a ContainerShapeAggregation from ShapeAggregation or GroupShapeAggregation
• Override the NotifyChildMoving/NotifyChildMoved methods and restrict the children's movements to the bounds of the Owner.
• Derive your shape from Shape and implement the interface IShapeGroup:
    public class ShapeGroup : Shape, IShapeGroup
  You can take a look at the implementation of class ShapeShape for the details.
• Use your ContainerShapeAggregation as Children collection.
• If you want to prevent the shapes to move out of the owner's bounds, you have to derive a set of shapes from the appropriate base classes.
