Thanks for your nice article. It is really helpful. I want some shapes (rectangle, ellipse, triangle) in a side of the windows. When I click on any shape, it will draw this shape on the another side of the window, I can be able to write within this shape, I can move or resize this shape. How can I do it?

I'm getting a 'NullReferenceException was unhandled' error when I try to move a rectangle. It highlights the line: <code> transform.Matrix = new Matrix(1, 0, 0, 1, CurrentPoint.X - StartPoint.X, CurrentPoint.Y - StartPoint.Y); </code>
