POto output CSV file for pop-up window using C# in ASP.Net
text
Body
copied!<p>I try to output CSV file in pop-up window. I can output CSV in main window, but not in pop-up. I use same code. For example; I use a form to output CSV file. When this form is main window, can output CSV file. When I use this form as a pop-up, it can't output. How can I do?</p> <p>It is my CSV output function:</p> <pre><code>public void OutputCSV(DataTable dtValue, string strFilename) { if (TextUtility.IsNullOrEmpty(strFilename)) { throw new I01Exception(Enums.ExType.System, "9909_35"); } DataTable dt = dtValue; StringBuilder sb = new System.Text.StringBuilder(); string strCh = ","; //項目名 for (int k = 0; k < dt.Columns.Count; k++) { sb.Append("\"" + dt.Columns[k].Caption + "\"" + strCh); } sb.Remove(sb.Length - 1, 1); //データ foreach (DataRow row in dt.Rows) { sb.AppendLine(string.Empty); for (int i = 0; i < dt.Columns.Count; i++) { sb.Append("\"" + row[i].ToString() + "\"" + strCh); } } HttpContext.Current.Response.Clear(); HttpContext.Current.Response.Buffer = true; HttpContext.Current.Response.AppendHeader("content-disposition", string.Format("attachment; filename={0}", HttpUtility.UrlEncode(strFilename + ".csv"))); HttpContext.Current.Response.ContentType = "text/comma-separated-values"; HttpContext.Current.Response.ContentEncoding = Encoding.GetEncoding("shift-jis"); HttpContext.Current.Response.Write(sb.ToString()); HttpContext.Current.Response.Flush(); HttpContext.Current.ApplicationInstance.CompleteRequest(); HttpContext.Current.Response.End(); } </code></pre>
