[英]Execute codes after Response.End()
我在Response.End()之后執行代碼時遇到麻煩。
我用它來導出數據表/ ASP表到MS Excel(.xls)。
導出完成,但是我的Gridview不再加載。 我用來加載gridview的命令是在Response.End()之后編寫的。
我嘗試使用HttpContext.Current.ApplicationInstance.CompleteRequest();
但這沒有幫助。
我也嘗試了Response.Redirect("Charges_Trs.aspx", false);
仍然沒有用..
請任何幫助..這是我的代碼
lblNotif.Text = "Selected items have been posted. Exporting XLS ... (will be saved in your desktop)";
exportToExcel(dt); //calls the function to export the datatable to excel, i passed dt=datatable to this function
timerNotif.Enabled = true;
btnSearch_Click(null, null); //called the event of a button that loads the gridview
這是函數exporttoexcel()
public void exportToExcel(DataTable dt)
{
Table dTable = new Table();
TableRow dTableRow = new TableRow();
//Column Headings
for (int i = 0; i < dt.Columns.Count; i++)
{
TableCell tCell = new TableCell();
tCell.Text = dt.Columns[i].ToString();
dTableRow.Cells.Add(tCell);
}
dTable.Rows.Add(dTableRow);
//Rows
for (int i = 0; i < dt.Rows.Count; i++)
{
dTableRow = new TableRow();
for (int j = 0; j < dt.Columns.Count; j++)
{
TableCell tCell = new TableCell();
dTableRow.Cells.Add(tCell);
}
dTable.Rows.Add(dTableRow);
}
if (Response.IsClientConnected)
{
Response.Clear();
Response.ClearContent();
Response.ClearHeaders();
Response.Buffer = true;
Response.AddHeader("content-disposition", "attachment;filename=PostedCharges" + DateTime.Now.ToString("MMddyyyy") + ".xls");
Response.Charset = "";
Response.ContentType = "application/vnd.ms-excel";
StringWriter sw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(sw);
dTable.RenderControl(hw);
string style = @"<style> .textmode { mso-number-format:\@; } </style>";
Response.Write(style);
Response.Output.Write(sw.ToString());
Response.Flush();
Response.End();
}
}
您可以在調用export之后嘗試在btnSearch click事件中添加代碼(希望將Grid與一些數據綁定),而不是調用click事件。
