Open aspx page in new window or tab

 Hi,
    I use the following code in a Buttons onClick handler.
 
Response.Redirect("~/Quotations/Reports/EIQuotationReport.aspx?QuoteNo="+SelectedQuoteNo);
Is it possible to open the EIQuotationReport.aspx web form in a new window or a new tab? I could change the button to a hyperlink if required.
Thanks
Paul.
