如何使用可拖动和可调整大小的属性动态添加Silverlight基元？

Question

Well I wanna please ask you how can I implement a ribbon for example that have primitives like line, ellipse, rectangle, point, etc ... So that the user can drag any of these primitives from the ribbon and drag it in the grid where he can drag, drop and resize the added primitive freely.

Thanks

I'm afraid that the Silverlight toolkit drag and drop classes won't help you here since you won't be using any standard drop target, so your options for the drag and drop are:

• Implement it manually, based on mouse events. Here's a basic example from the MSDN . Also, here's a nice article on how you could do this with behaviors: Expression Blend 3: Trying a drag-and-drop behavior .
• Use ComponentOne DragDropManager (not free).
• Use Telerik DragDropManager (not free).
