"It didn't worked" is not pretty informative. Please elaborate.
Anyway, I suppose you are missing a conversion from Screen to Client coordinates (or the opposite). Have a loook at Mouse Events in Windows Forms[^] and at Control.PointToClient Method (Point) (System.Windows.Forms)[^] (for sample code).

to complete the Solution from CPallini a Little bit :

If you do a MouseDown on your Form you have to look it the actual MousePosition is at a coordinate-range of one of your rectangles.
If Yes you should memorize the actual MousePosition relative to the Rectangle-Postion.
If you now move your Mouse while it is pressed you could change the Rectangle-Postion according to this Movement.
But all this is not done automaticly - you have to code everything.

To be more specific you should improve your question with lots of more Info ... sorry ... :(
