I am creating an application in c#.NET 3.5 similar to Microsoft Power point.
I am having provisions to draw shapes and place controls in a page.
When user selects multiple pages, I need to show that the controls and shapes in the page are selected with a rubber band drawn around them.
Based on the selection, I would need to have the same functionalities of a selected control / shape such as resizing, moving, deleting etc.
Please let me know what I should do in the code to show that a control or a shape is 'selected' in the page.

You have three basic options:
(1) Increase the size of the control when it is selected so that the rubberband is drawn within the bounds of the control but appear to the user to be outside of it.
(2) Draw the rubberband directly to the screen with ControlPaint.DrawReversibleFrame().  This will allow you to draw outside of the bounds of the control but it may get erased when other controls/windows obscure the rubberband.
(3) Make the container of the controls draw the rubberbands instead.
