Printing and aspx web page

Hi, I'm trying to print an aspx page, however I only want it to print the contents inside the editable content placeholder. The reason for this is because I don't want to print the whole web page including the menu bar and logo.

In the placeholder there is a graph and a grid view.
I'm unsure whether I should tackle this problem in  javascript or C#.

Thank you for your help in advance.
