open an external link in a new tab from within an asp.net project

Question

I am planning to open an external link ("www.google.com") in a "new tab of the same window" from within my asp.net project on button click. Is there a way to do it. (The links come from the database and looks like I cant do it in markup side).

Currently I tried , response.redirect & window.open but both don't seem to work.

Response.Redirect
 protected void btnSubmit_Click(object sender, EventArgs e)
        {
           Response.Redirect("www.google.com");
        }

Window.Open

 protected void btnSubmit_Click(object sender, EventArgs e)
      {   
string x = "www.google.com";

       string s = "window.open('" + x + "', 'popup_window', 'width=300,height=100,left=100,top=100,resizable=yes');";

        ClientScript.RegisterStartupScript(this.GetType(), "script", s, true);
  }

The error I get in both cases is : 404 page not found..

Did you notice the error message... the 'Requested URL' shows the reason for the issue. Is it okay to use jquery in your application? In my project, I am using a jquery based solution to achieve similar functionality. — JGV, Sep 06 '15 at 19:33
Yes ! I can use jquery .. Please let me know how I can achieve it in jquery. The error was because I should use "http://www.google.com" instead of "www.google.com". Also, I need to open the new url in a new tab. Response.redirect opens the new url in the same window. — CodeNinja, Sep 06 '15 at 21:27

Notice the URL being requested:

http://localhost/www.google.com

If you're directing the user to another site, you have to fully-qualify the URL:

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

or:

string x = "http://www.google.com";

Otherwise the browser thinks it's looking for a resource called "www.google.com" on the current site.

Thanks that works partially, but as I mentioned in my question I want to open the new url as a "new tab of the same window". How can I do that ? The above solution opens the url as a new window. – CodeNinja Sep 06 '15 at 21:34
@CodeNinja: The JavaScript `window.open()` should do exactly that. Is that not working in your browser? – David Sep 06 '15 at 21:37
The window.open() is opening in a new window instead of a new tab on the same window. I am using internet explorer. The code is below. string x = "https://www.google.com"; string s = "window.open('" + x + "', 'popup_window', 'width=300,height=100,left=100,top=100,resizable=yes');"; ClientScript.RegisterStartupScript(this.GetType(), "script", s, true); – CodeNinja Sep 06 '15 at 21:43
@CodeNinja: It's up to the browser how to open the new window object, whether it's a tab or a separate window. The code can't control that: http://stackoverflow.com/questions/4907843/open-a-url-in-a-new-tab-using-javascript – David Sep 06 '15 at 21:46

What you can do is send a chunk of html down the response that has a link with your url as an href, target="_blank" and a chunk of javascript onload of the form that fakes a click. If this doesn't work then use a window.open("www.google.com");

response.write("<script>");
response.write("window.open('www.google.com','_blank')");
response.write("</script>");

You have to specify the full URL, so use

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

Goodluck.

Hey Slashy ! Thanks ! But the above solution opens the url "www.google.com" in the same window. As I mentioned in my question, I would like to open the new link "as a new tab in the same window". How can I do that ? – CodeNinja Sep 06 '15 at 21:31

Try:

 protected void btnSubmit_Click(object sender, EventArgs e)
    {
        string x = "https://www.google.com";

        string s = "window.open('" + x + "', 'popup_window', 'width=300,height=100,left=100,top=100,resizable=yes');";

        ClientScript.RegisterStartupScript(this.GetType(), "script", s, true);
    }

Edit 2:

According to This, you can't open it in new window in this way.

if you really want it in a new Window then use HTML Links with target="_blank" attribute.

The URL www.google.com is interpreted as local path, try

http://www.google.com

instead.

Using _new as window name opens a new window or tab:

window.open("...", "_new")
