Menu onclick event should not scroll page

On that page where I integrate a context menu with a grid, if I click one of the items in the context menu that action causes the page to scroll to the top. How do I prevent that. What part of the code does the scrolling. I want the page to stay in place while I click on the menu in the grid.

We need the complete demo. If you are using Grid PRO, please create ticket at Members’ Support and attach sample there.
