Need source code for browser drag and drop application.

I want to code a simple application that allows you to drag and drop HTML components directly onto a webbrowser and have them stay in place (like getting the x, y and size data and creating a DIV for the item when it is dropped onto the webbrowser portion of the application).

Actually I want to create a replica of the Wix online flash-based editor, only I don't want it to be online (not yet anyway) and I don;t want to use flash (that's www.wix.com if you want to check it out).

Any .Net code examples showing how to do something similar (like dragging and dropping HTML code to a browser window and being able to drag it wherever you want) would make my whole week.
