Hi Sudheer

   I have a very similar problem. I have create a page with a warp from this i trigger a link to a new windows that dowmloads a file using the exportexcel or Response.BinaryWrite.

   Everything work really nice in my local computer using IE7 and visual studio. When I deploy the application to the server it only work fine with IE6 but not with IE7 .IE7 closes the new window without showing any error message.

  Is infragistic not compatible with IE7 for exporting grids to excel and pdf????? Have you some answer

 Have you found a reason for that???? Please help.. I need that as soon as possible. Thanks Sudheer. Below my code:

        if (contentReportDs != null)
        {
            uwgExportReport.DataSource = contentReportDs;
            switch (Convert.ToInt32(Enum.Parse(outputFormatReceived, outputFormat)))
            {
                case 0: // CSV file
                    if (this.loadPlugin(outputFormat, ref aMessage))
                    {
                        Panel csvPanel = ((Panel)this.plugin.generate(this.wpDownloadReport, contentReportDs));
                        Label csvLabel = new Label();
                        for(int i=0; i<csvPanel.Controls.Count;i++)
                            if (csvPanel.Controls[i] is Label)
                                csvLabel = csvPanel.Controls[i] as Label;

                        string csvContentToShow = csvLabel.Text;
                        csvContentToShow = csvContentToShow.Replace("<br />", "" + '\n');
                        byte[ bytFile = System.Text.Encoding.UTF8.GetBytes(csvContentToShow);
                        Response.Clear();
                        Response.Buffer = true;
                        Response.ContentType = "application/vnd.ms-excel";
                        Response.AddHeader("content-disposition", "attachment;filename=" + fileName);

                        Response.Charset = "";
                        Response.Cache.SetCacheability(HttpCacheability.NoCache);

                        // If you write,
                        // Response.Write(bytFile1);
                        // then you will get only 13 byte in bytFile.
                        Response.BinaryWrite(bytFile);

                        Response.End();
                       
                    }
