You want to use Response.Reidrect and specify the target frame/window. I googled "asp.net response target", and this was one of the more than 4.6 MILLION results returned:

C#

public static class ResponseHelper 
{
    public static void Redirect(this HttpResponse response, string url, string target, string windowFeatures)      
    {
        if ((String.IsNullOrEmpty(target) || target.Equals("_self", StringComparison.OrdinalIgnoreCase)) && String.IsNullOrEmpty(windowFeatures))          
        {  
            response.Redirect(url);
        }
        else
        {
            Page page = (Page)HttpContext.Current.Handler;
            if (page == null)
            {
                throw new InvalidOperationException("Cannot redirect to new window outside Page context.");
            }
            url = page.ResolveClientUrl(url);
            string script;
            if (!String.IsNullOrEmpty(windowFeatures))
            {
                script = @"window.open(""{0}"", ""{1}"", ""{2}"");";
            }
            else
            {
                script = @"window.open(""{0}"", ""{1}"");";
            }
            script = String.Format(script, url, target, windowFeatures);
            ScriptManager.RegisterStartupScript(page, typeof(Page), "Redirect", script, true);
        }      
    } 
}

With this you get nice override on the actual Response object

C#

Response.Redirect(redirectURL, "_blank", "menubar=0,scrollbars=1,width=780,height=900,top=10");

Google reveals all.

Hi,

                                        <option value="www.google.com">your url</option>
                                        <option value="www.yahoo.com">your url</option>
                                    </select>

Javascript:

function ViewiNewWindow(val)
{
   var url = val;
   window.open(url ,'mywindow','width=400,height=200,left=0,top=100,screenX=0,screenY=100')
