Opening new window from button/link button on 2.0/3.5

I Googled for the solution and never found one that is simple, short and to the point. Here is the fastest solution to opening a link in a new page if you are using a button or a link button on ASP.NET 2.0/3.5. Add this attribute to your button. This goes on your page load section of the code.
button1.Attributes.Add("onclick", "'somepage.aspx');")
Unfortunately I could not find a solution using response.redirect
