How do I export data from a GridView to a .txt

I'm working on a C# asp.net project and can't seem to get the "exporting to a .txt file from a grid view" to work.
protected void ExportGridToText() {
BindGridView();
Response.Clear();
Response.Buffer = true;
Response.Charset = "";
StringBuilder Rowbind = new StringBuilder();
Response.ContentType = "application/text";
Response.AddHeader("Content-Disposition", "attachment;filename=GlogData.txt");
Response.ContentEncoding = System.Text.Encoding.Unicode;
Response.BinaryWrite(System.Text.Encoding.Unicode.GetPreamble());
Response.Cache.SetCacheability(HttpCacheability.NoCache);
gvLog.DataBind();
for (int i = 2; i < gvLog.Columns.Count; i++)
{
Rowbind.Append("\"" + gvLog.Columns[i].HeaderText + "\"" + ',');
}
Rowbind.Append("\n");
for (int j = 0; j < gvLog.Rows.Count; j++)
{
for (int k = 0; k < gvLog.Columns.Count; k++)
{
Rowbind.Append("\"" + gvLog.Rows[j].Cells[k].Text + "\"" + ',');
Rowbind.Replace("<", "<");
Rowbind.Replace(">", ">");
}
Rowbind.Append("\n");
}
gvLog.AllowPaging = false;
Response.Output.Write(Rowbind.ToString());
Response.Flush();
Response.End();
}
Evrytime I run the code I get a error message:
Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed
Why is it giving me this error?
How do I fix it?
Is it possible to get the data from the source... This is under the get Button that populates the GridView:
protected void GetLogBtn_Click(object sender, EventArgs e)
{
string sBeginDate = BeginDate.Text;
string sEndDate = EndDate.Text;
JObject vResultJson = new JObject();
FKWebCmdTrans cmdTrans = new FKWebCmdTrans();
DateTime dtBegin, dtEnd;
if (sBeginDate.Length > 0)
{
try
{
dtBegin = Convert.ToDateTime(sBeginDate);
sBeginDate = FKWebTools.GetFKTimeString14(dtBegin);
vResultJson.Add("begin_time", sBeginDate);
}
catch
{
BeginDate.Text = "";
}
}
if (sEndDate.Length > 0)
{
try
{
dtEnd = Convert.ToDateTime(sEndDate);
sEndDate = FKWebTools.GetFKTimeString14(dtEnd);
vResultJson.Add("end_time", sEndDate);
}
catch
{
EndDate.Text = "";
}
}
try
{
string sFinal = vResultJson.ToString(Formatting.None);
byte[] strParam = new byte[0];
cmdTrans.CreateBSCommBufferFromString(sFinal, out strParam);
mTransIdTxt.Text = FKWebTools.MakeCmd(msqlConn, "GET_LOG_DATA", mDevId, strParam);
Session["operation"] = GET_LOG_DATA;
GetLogBtn.Enabled = false;
ClearBtn.Enabled = false;
Timer.Enabled = true;
}
catch (Exception ex)
{
StatusTxt.Text = "Fail! Get Log Data! " + ex.ToString();
}
}
This is under the BindGridView:
private void BindGridView()
{
try
{
string mTransid = mTransIdTxt.Text;
string strSelectCmd = "SELECT COUNT(*) FROM tbl_fkcmd_trans_cmd_result_log_data where trans_id = '" + mTransid + "'";
SqlCommand sqlCmd = new SqlCommand(strSelectCmd, msqlConn);
SqlDataReader sqlReader = sqlCmd.ExecuteReader();
if (sqlReader.HasRows)
{
if (sqlReader.Read())
nCount = sqlReader.GetInt32(0);
}
sqlReader.Close();
sqlCmd.Dispose();
{
DataSet dsLog = new DataSet();
strSelectCmd = "SELECT * FROM tbl_fkcmd_trans_cmd_result_log_data where trans_id = '" + mTransid + "'";
SqlDataAdapter da = new SqlDataAdapter(strSelectCmd, msqlConn);
// conn.Open();
da.Fill(dsLog, "tbl_fkcmd_trans_cmd_result_log_data");
DataView dvLog = dsLog.Tables["tbl_fkcmd_trans_cmd_result_log_data"].DefaultView;
gvLog.DataSource = dvLog;
gvLog.DataBind();
StatusTxt.Text = " Total Count : " + Convert.ToString(nCount) + " Current Time :" + DateTime.Now.ToString("HH:mm:ss tt");
}
}
catch (Exception ex)
{
StatusTxt.Text = ex.ToString();
}
}
I hope this helps
Thanks in advance

Following Code is For Excel Mainly...but its successfully converting gridview to .txt file just need a little workaround..
public void ExportToExcel(System.Web.UI.WebControls.GridView controlname, string sheetname)
{
HttpContext context = HttpContext.Current;
context.Response.ClearContent();
context.Response.Buffer = true;
context.Response.AddHeader("content-disposition", string.Format("attachment; filename={0}", sheetname + ".txt"));
context.Response.ContentType = "application/text";
// context.Response.AddHeader("content-disposition", string.Format("attachment; filename={0}", sheetname + ".xls"));
// context.Response.ContentType = "application/ms-excel";
StringWriter sw = new StringWriter();
HtmlTextWriter htw = new HtmlTextWriter(sw);
//Change the Header Row back to white color
controlname.HeaderRow.Style.Add("background-color", "#FFFFFF");
//Applying stlye to gridview header cells
for (int i = 0; i < controlname.HeaderRow.Cells.Count; i++)
{
controlname.HeaderRow.Cells[i].Style.Add("background-color", "#507CD1");
}
int j = 1;
//This loop is used to apply stlye to cells based on particular row
foreach (GridViewRow gvrow in controlname.Rows)
{
gvrow.BackColor = Color.White;
if (j <= controlname.Rows.Count)
{
if (j % 2 != 0)
{
for (int k = 0; k < gvrow.Cells.Count; k++)
{
gvrow.Cells[k].Style.Add("background-color", "#EFF3FB");
}
}
}
j++;
}
controlname.RenderControl(htw);
context.Response.Write(sw.ToString());
context.Response.End();
}

return File (memory stream) encoding

Hi I have problem to return right encoded file.
finalString is here only for my control of encoding and show me right strings, but returned excel file dont contain right czech characters... (Č č š Š Ž etc...) Can someone help me?
byte[] bytes = encode.GetBytes(str.ToString());
string finalString = encode.GetString(bytes);
Here is complete class:
public async Task<IActionResult> ExportExcel()
{
// List<Material> obj = new List<Material>();
// obj = await _context.Material.ToListAsync();
StringBuilder str = new StringBuilder();
str.Append("<table border=`" + "1px" + "`b>");
str.Append("<tr>");
str.Append("<td><b>Id</b></td>");
str.Append("<td><b>Name</b></td>");
str.Append("</tr>");
// foreach (Material val in obj)
// {
str.Append("<tr>");
str.Append("<td>" + "0" + "</td>");
str.Append("<td>" + Česnek + "</td>");
str.Append("<td><font face=Arial Narrow size=" + "14px" + ">" + val.Name.ToString() + "</font></td>");
str.Append("</tr>");
// }
str.Append("</table>");
string uc = Configuration.UserCulture;
int codepage = 1250; // _cultureDataProvider.GetAnsiCodePage(uc);
Encoding encode = Encoding.GetEncoding(codepage);
byte[] bytes = encode.GetBytes(str.ToString());
string finalString = encode.GetString(bytes);
MemoryStream stream = new MemoryStream(bytes);
return File(stream, "application/vnd.ms-excel", "excel.xls");
/*
HttpContext.Response.Headers.Add("content-disposition", "attachment; filename=Information" + DateTime.Now.Year.ToString() + ".xls");
this.Response.ContentType = "application/vnd.ms-excel";
byte[] temp = System.Text.Encoding.ASCII.GetBytes(str.ToString());
return File(temp, "application/vnd.ms-excel");
*/
}

I was able to solve it after one day - csv and tab .txt file solution: (working under Core CLR)
public async Task<IActionResult> Export(string type)
{
string _OuputType = type.ToLower().Trim();
string _delimiter = _OuputType.Contains("csv") ? ";" : String.Empty;
_delimiter = _OuputType.Contains("txt") ? "" : _delimiter;
IEnumerable<Material> data = await _context.Material.Include(m => m.Unit).ToListAsync();
StringBuilder str = new StringBuilder();
//file name
string fileName = "Material-" + DateTime.Now.ToString("dd_MM_yyyy-H_mm_ss");
//head
str.Append("Name" + _delimiter + "\t");
str.Append("AutoPlan" + _delimiter + "\t");
str.Append("QuantityMinStock" + _delimiter + "\t");
str.Append("QuantityMaxStock" + _delimiter + "\t");
str.Append("QuantityPurchase" + _delimiter + "\t");
str.Append("Unit" + _delimiter + "\t");
str.Append("\r\n");
//data
foreach (Material m in data)
{
str.Append(m.id + _delimiter + "\t");
str.Append(m.Name + _delimiter + "\t");
str.Append(m.AutoPlan + _delimiter + "\t");
str.Append(m.QuantityMinStock + _delimiter + "\t");
str.Append(m.QuantityMaxStock + _delimiter + "\t");
str.Append(m.QuantityPurchase + _delimiter + "\t");
str.Append(m.Unit.LocalizedCode + _delimiter + "\t");
str.Append("\r\n");
}
// int codepage = _cultureDataProvider.GetAnsiCodePage(Configuration.UserCulture); == This is my service to get code page (example: 1250, or 1252 etc...)
Encoding encode = Encoding.GetEncoding(_cultureDataProvider.GetAnsiCodePage(Configuration.UserCulture));
byte[] bytes = encode.GetBytes(str.ToString());
if (_OuputType == "txt"){return File(bytes, "text/plain", fileName + ".txt");}
return File(bytes, "application/msexcel", fileName + ".csv");
}

ANSI does not provide valid encoding for Č, č, š, Š, Ž you should look for more suitable codepages like UTF-8, UTF-16, UTF-32, etc....
byte[] bytes = Encoding.UTF8.GetBytes(str.ToString());
string finalString = Encoding.UTF8.GetString(bytes);
Did you try to work using Office Interop? It would be more ease and right way to work with Excel.

You can use SetData method to print tables to excel files.
Simple instruction:
Create instance of class;
Initialize world application by calling public void Initialize(bool visible) visible controll the wisibility of Excell window.
Create new workbook by calling CreateWorkbok;
And worksheet by CreateWorksheet;
Work with worksheet SetData - prints table DataTable;
Work with text SetText.
To save and close use SaveCurrentWorksheet and CloseCurrentWorksheet.
ExcelManager excel_manager = new ExcelManager()
excel_manager.Initialize(true);
excel_manager.CreateWorkbook();
excel_manager.CreateWorksheet();
excel_manager.SetText("Česnek!", 1, 0, 0);
excel_manager.SetData(systemTable, 0, 0, 2);
excel_manager.SetText("Лог консолі!", 1, 0, 3);
The result of calls:
Or you can use Open XML SDK for Office, to support multitask in your web application.

Export DataTable to Excel and save to local directory

I have below functions that take Data Table and convert to excel and prompt user to download the excel.
May I know how can I change the function so that it is save to my local directory instead of download?
public static void ExportDataTableToExcel(DataTable table, string name)
{
HttpContext context = HttpContext.Current;
context.Response.Clear();
string attachment = "attachment; filename=" + name + ".xls";
context.Response.ClearContent();
context.Response.AddHeader("content-disposition", attachment);
context.Response.ContentType = "application/vnd.ms-excel";
context.Response.ContentEncoding = System.Text.Encoding.Unicode;
context.Response.BinaryWrite(System.Text.Encoding.Unicode.GetPreamble());
string tab = "";
foreach (DataColumn dc in table.Columns)
{
context.Response.Write(tab + dc.ColumnName);
tab = "\t";
}
context.Response.Write("\n");
int i;
foreach (DataRow dr in table.Rows)
{
tab = "";
for (i = 0; i < table.Columns.Count; i++)
{
context.Response.Write(tab + "=\"" + dr[i].ToString() + "\"");
tab = "\t";
}
context.Response.Write("\n");
}
context.Response.End();
}

Found and implemented the function
public static bool SaveDataTableToExcel(DataTable table, string savePath)
{
//open file
StreamWriter wr = new StreamWriter(savePath, false, Encoding.Unicode);
try
{
for (int i = 0; i < table.Columns.Count; i++)
{
wr.Write(table.Columns[i].ToString().ToUpper() + "\t");
}
wr.WriteLine();
//write rows to excel file
for (int i = 0; i < (table.Rows.Count); i++)
{
for (int j = 0; j < table.Columns.Count; j++)
{
if (table.Rows[i][j] != null)
{
wr.Write("=\"" + Convert.ToString(table.Rows[i][j]) + "\"" + "\t");
}
else
{
wr.Write("\t");
}
}
//go to next line
wr.WriteLine();
}
//close file
wr.Close();

LogError(ex);

Datatable to csv write to zip download error: because it is being used by another process

In thst code i have us two database tabele and fetch data in datatable then write all the data in the csv files with help of stream writer then add both the file in a folder and download in a zip form but sometimes its shows an error The process cannot access the file 'xxxxx.zip' because it is being used by another process.

I am exporting the data to excel 2003.
The exported excel is of the type .xls in IE and Chrome.
But it is not .xls type in mozilla.When open that file, it is asking which program you want to open?
What is the reason?
