Need help redirecting

I have a dashboard with a form and a grid. The dashboard is in a menu. When the record on the form is saved, it redir to a blank application via a button link. It redirects in the same window because the grid is a progress indicator that will not work if in another window. When the program is completely done, I need to have the dashboard displayed as if I had just opened it originally with the form and the grid. How do I get it to do this? Even a javascript button as on a modal would work.
