Response.Redirect to New Window

Response.Redirect() in new window in Asp.Net

Opening a new window in almost all browsers nowadays has to be invoked from a user click event. Almost all browsers (and this covers about 99% of cases) will block a popup that is invoked from a page load event, so I suggest you reconsider your solution, probably by showing a link that would open in new window.

What I would do, is open the new window on the click event, which would open your processing page, which in turn will redirect to whatever page you want. Basically, first open the popup with click event, and then do the redirect in your new page.

How to open the page in new window using response.redirect in c#

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.

how to open page in new tab with response.redirect or response.write

try this:

missing +"

 Response.Write("<script type='text/javascript'>");
 Response.Write("window.open('DeliveryChallanPrint1.aspx?val="+this.txtPoNo.Text+"','_blank');"); 
 Response.Write("</script>");

How do I use Target=_blank on a response.redirect?

You can't is the short answer. The browser is the only thing that can open up a new window.

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(url);

response.write("<script>");
response.write("window.open('page.html','_blank')");
response.write("</script>"); 

Using Window.Open instead of Response.Redirect to open new window?

This code below ultimately does exactly what I needed it to:

<a href="<%= this.ResolveUrl("Search.aspx?id=" + lblGraphicNameValue.Text.Remove(lblGraphicNameValue.Text.Length -4)) %>"
                                                                                target="_blank">Search Related</a>

This code does three things:

• 1) Opens Search in new page.
• 2) Truncates the search value by four
  characters (I only needed part of the search string)
• 3) Passes in
  parameter to new page.

This accomplished exactly what I needed without resorting to custom classes or javascript, although it did make me have to use a link instead of a button.
