POFile download dialog IE7 disappears

Body
copied!<p>The following code will not run correctly in IE7 with the latest service packs installed.</p> <pre><code>System.Web.HttpResponse response = System.Web.HttpContext.Current.Response; response.Clear(); response.AddHeader("Content-Disposition", "attachment;filename=Contacts.xls"); response.ContentType = "application/octet-stream"; System.Text.UnicodeEncoding Encoding = new System.Text.UnicodeEncoding(); byte[] unicodeBytes = {255,254}; int length = 2 + Encoding.GetByteCount(_exportContent); // _exportContent is string. response.AddHeader("Content-Length", length.ToString()); response.OutputStream.Write(unicodeBytes, 0, 2); unicodeBytes = Encoding.GetBytes(_exportContent); response.OutputStream.Write(unicodeBytes, 2, unicodeBytes.Length); response.End(); </code></pre> <p>I am opening the aspx page with js (window.open()) and execute the above code in the Page_Load().</p> <p>The strange thing is that the window pops up, tries to load/show the file dialog and then you hear the sound like a popup window has been blocked (although popup blocker is deactivated!).</p> <p>Extra information:<br> - The behavior happens both on XP and W2k3 (which is a real web server without anything else installed but IE7 & FW 3.5 SP1 & latest service packs.) - The same code works fine with FW 2.0 - Firefox has no problems to display a file dialog.</p> <p>I would be curious if anyone else has ran into the same problem and could provide a solution for getting the thing working in IE7.</p> <p>Cheers,<br> Dimi</p>
