How to open a page in a new window or tab from code-behind

Question

So I have a webapplication where I select a value from a dropdownlist. When this value is selected, I want to load another page in a new window.

I tried this:

ScriptManager.RegisterStartupScript(Page, typeof(Page), "OpenWindow", "window.open('Default.aspx', '_blank');", true);

It does open the page, but not in a new window/tab. It opens it in the current opened page.

Alternatively I tried:

ClientScript.RegisterStartupScript(this.GetType(), "OpenWin", "<script>openDashboardPage()</script>");

and

HttpContext.Current.Response.Write("<SCRIPT LANGUAGE='JavaScript'>window.open('Default.aspx', '_new');</SCRIPT>");

They all behave in the same fashion. I just loads the page in the existing window. I tried it in both Firefox and Chrome, thinking it might be a browser thing, but they both behaved the same.

How do I open a new window?

Try this one

string redirect = "<script>window.open('http://www.google.com');</script>"; 
Response.Write(redirect);
