Click event

Question

I have a screen grab section in my program that when a user raises the mouse_click event a rubber band box is drawn to the point the user raises the mouse_up event, at this point 3 button apear (Clip, Save and Cancel).
This all works fine providing the user clicks on the form for the form click event.
What I want to be able to do is allow the user to click anywhere on the form regardless of it been a "form, textBox, label" or any other type and start the rubber band box from that location without having to set the click event for each object.

Can anyone help me with this.

I am using VS 2010
C# forms.

Thanks.
