how to perform calculation between cells under a datagridview control using C#.net

Question

I want to perform calculation like multiplication, addition etc between cells. How could I do this using datagridview control? For your kind information, I am using visual studio 2005 and using C#. UltraCalcManager is available in visual studio 2005 or not. This control is used for any calculation. I can not be able to find this control in toolbars in visual studio 2005.
