Question

Can anybody suggest how we can open the page in new window using Response.Redirect in c#, I know we can do it using response.write as given below:

Response.Write("<script>");
Response.Write("window.open('"+url+"','_blank')");
Response.Write("</script>");

But what when javascript is disabled, the above code will not run.

Please suggest!!

As Tom Gullen suggested that is the only way.
I am assuming you’re using ASP.NET.

You can create a public function which receives the Url you want to open in the new windows.
This function then redirects to a page which does the dirty job.

Public Function ResponseRedirect(ByVal urlRedirect As String) As Boolean
    HttpContext.Current.Response.Redirect("Redirector.aspx?goto=" & HttpUtility.UrlEncode(urlRedirect))
End Function

This is Redirector.aspx

Public Partial Class Redirector
    Inherits System.Web.UI.Page

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        Dim OpenNewPage As String = ""
        If Request.QueryString("goto") IsNot Nothing Then
            Me.OpenNewPage = Request.QueryString("goto")
        End If
        If Request.UrlReferrer.AbsoluteUri IsNot Nothing Then
            Me.Referer = Request.UrlReferrer.AbsoluteUri
        End If
    End Sub

    Private _OpenNewPage As String = ""
    Public Property OpenNewPage() As String
        Get
            Return _OpenNewPage
        End Get
        Set(ByVal value As String)
            _OpenNewPage = value
        End Set
    End Property

    Private _Referer As String = ""
    Public Property Referer() As String
        Get
            Return _Referer
        End Get
        Set(ByVal value As String)
            _Referer = value
        End Set
    End Property

End Class

and the HTML of Redirector.asp

<script type="text/javascript">
    window.open('<%=Me.OpenNewPage%>', '_blank', '');
    window.document.location.href = '<%=Me.Referer%>';
</script>

It’s not really really elegant code but it does the trick.
Obviously, if javascript is disabled it doesn’t work.

I’ve put together a sample here.
Hope it helps.
