Open any url in popup and redirect current page in ASP.net without any button click on page load

Question

When someone opens my webpage I would like a popup to open, and then I would like the main page (not the popup) to redirect to another website.

I have tried:

ClientScript.RegisterStartupScript(
    this.GetType(),
    "popup",
    "<script language=javascript>window.open('http://someURL.com','PrintMe','height=650px,width=1024px,scrollbars=1');</script>");           

followed by

Response.Redirect("http://www.google.com");

While the redirection is working properly, the popup is not being displayed.

You can use below code:

Common function for open PopUp window:

put this function at your common master page

function PopupCenter(url, title, w, h) {
     var child;
     var timer;
     var guid;

    var dualScreenLeft = window.screenLeft != undefined ? window.screenLeft : screen.left;
    var dualScreenTop = window.screenTop != undefined ? window.screenTop : screen.top;

    width = window.innerWidth ? window.innerWidth : document.documentElement.clientWidth ? document.documentElement.clientWidth : screen.width;
    height = window.innerHeight ? window.innerHeight : document.documentElement.clientHeight ? document.documentElement.clientHeight : screen.height;

    var left = ((width / 2) - (w / 2)) + dualScreenLeft;
    var top = ((height / 2) - (h / 2)) + dualScreenTop;

    child = window.open(url, title, 'scrollbars=yes, width=' + w + ', height=' + h + ', top=' + top + ', left=' + left);

    if (child.focus) {
        child.focus();
        parent.location.assign("http://blabla.com/");// Change parent Page location
    }
}

and Call this function like below:

PopupCenter('http://www.google.com', 'Widow Title', '1000', '1000');

in your case you have top apply like this:

Page.ClientScript.RegisterStartupScript(this.GetType(),"CallMyFunction","PopupCenter('http://www.google.com', 'Widow Title', '1000', '1000');",true);

Hope it will help you.
