I am unable to understand your problem. Cut-copy-paste should be implemented within the UserControl. Please make it a bit clear what you are looking for.

What technology are you using, Windows or Web? It makes a big difference in the answer.

I have a panel on which there are many usercontrol of different type. when I click on panel and move clicked mouse then It draws a rectangle between mouse down position and mouse current position. After mouse up I want to know which user controls are get selected (means In that particular rectangle). so that I can perform operation on it like copy paste.

After your comment:

Sorry, I misremembered. I should have said Intersect.

You have a rectangle that you have drawn. You can get the Bounds property of the controls in turn (search for 'c# iterate controls') to find out how, which is a rectangle. Then for each control use:

C#

if (Rectangle.Intersect(myDrawnRectangle, controlBoundsRectangle) != Rectangle.Empty)
{
   // part of the control is in your rectangle
   // do what you want with it.
}

Good luck! :)
