As far as Drawing Rectangle from Toolbox is Required on Click of toolbox tool you have to capture that info what you are going to draw on Screen and you have to Handle them mouseLeftbuttonDown even,MouseMove event and MouseLeftbutton up event .In these event you have tos et size accordingly of your Control which you are going to draw.

Based on Mouse Cordinates you have to increase and decrease its size.

Hi,

Presently i am not having any such sample code.

But i will suggest you to check how it is creating in Xaml and then use some custom logic according to that in your c# code.

If you are facing any issue please let me know i will  try to help you..

If you take a look at my Visio-esque project here, http://www.damonpayne.com/2008/10/10/RunTimeIsDesignTimeForAGT13.aspx ,

I am drawing Rectangles etc. at runtime on a Designer surface.  Code is included with the articles.
