you can open new window from asp net code behind using ajax like I did here http   alexandershapovalov com open-new-window-from-code-behind-in-aspnet-68   protected void Page Load object sender  EventArgs e        Calendar1 SelectionChanged    CalendarSelectionChanged     private void CalendarSelectionChanged object sender  EventArgs e        DateTime selectedDate     Calendar  sender  SelectedDate      string url    HistoryRates aspx date     HttpUtility UrlEncode selectedDate ToShortDateString         ScriptManager RegisterClientScriptBlock this  GetType     rates    selectedDate   openWindow      url          true

You can use this as extension method  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    amp  amp  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  Response Redirect redirectURL    blank    menubar 0 scrollbars 1 width 780 height 900 top 10

You may want to use the Page RegisterStartupScript to ensure that the javascript fires on page load

If you can re-structure your code so that you do not need to postback  then you can use this code in the PreRender event of the button   protected void MyButton OnPreRender object sender  EventArgs e        string URL      MyPage aspx       URL   Page ResolveClientUrl URL       MyButton OnClientClick    window open      URL        return false

The fixform trick is neat  but    You may not have access to the code of what loads in the new window  Even if you do  you are depending on the fact that it always loads  error free  And you are depending on the fact that the user won t click another button before the other page gets a chance to load and run fixform    I would suggest doing this instead   OnClientClick  aspnetForm target    blank  setTimeout  fixform     500      And set up fixform on the same page  looking like this   function fixform        document getElementById  aspnetForm   target

I just found the answer and it works     You need to add the following to your server side link button   OnClientClick  aspnetForm target    blank      My entire button code looks something like    lt asp LinkButton ID  myButton  runat  server  Text  Click Me                    OnClick  myButton Click                   OnClientClick  aspnetForm target    blank     gt    In the server side OnClick I do a Response Redirect  MyPage aspx    and the page is opened in a new window   The other part you need to add is to fix the form s target otherwise every link will open in a new window  To do so add the following in the header of your POPUP window    lt script type  text javascript  gt      function fixform             if  opener document getElementById  aspnetForm   target      blank   return          opener document getElementById  aspnetForm   target               opener document getElementById  aspnetForm   action   opener location href         lt  script gt    and   lt body onload  fixform    gt

I used Hyperlink instead of LinkButton and it worked just fine  it has the Target property so it solved my problem  There was the solution with Response Write but that was messing up my layout  and the one with ScriptManager  at every refresh or back was reopening the window  So this is how I solved it    lt asp HyperLink CssClass  hlk11  ID  hlkLink  runat  server  Text   lt    Eval  LinkText     gt   Visible   lt      bool Eval  IsDocument     gt   Target   blank  NavigateUrl   lt    Eval  WebAddress     gt   gt  lt  asp HyperLink gt

This is not possible with Response Redirect as it happens on the server side and cannot direct your browser to take that action  What would be left in the initial window  A blank page

You can also use in code behind like this way  ClientScript RegisterStartupScript this Page GetType           window open  page aspx   Graph   height 400 width 500      true

Because Response Redirect is initiated on the server you can t do it using that    If you can write directly to the Response stream you could try something like   response write   lt script gt     response write  window open  page html    blank      response write   lt  script gt

Here s a jQuery version based on the answer by  takrl and  tom above  Note  no hardcoded formid  named aspnetForm above  and also does not use direct form target references which Firefox may find problematic     lt asp Button ID  btnSubmit  OnClientClick  openNewWin      Text  Submit  OnClick  btn OnClick  runat  server   gt    Then in your js file referenced on the SAME page   function openNewWin             form   attr  target    blank        setTimeout  resetFormTarget     500      function resetFormTarget           form   attr  target

I used this approach  it doesn t require you to do anything on the popup  which I didn t have access to because I was redirecting to a PDF file   It also uses classes     function            --- setup click event for elements that use a response redirect in code behind but should open in a new window         new-window   on  click   function                 --- change the form s target             aspnetForm   prop  target     blank               --- change the target back after the window has opened         setTimeout function                      aspnetForm   prop  target                   1                 To use  add the class  new-window  to any element  You do not need to add anything to the body tag  This function sets up the new window and fixes it in the same function
