Export Data table With Arabic Data to Excel - asp.net

I am Having a Data Table which consists of arabic data.
When I am Exporting it to excel I am unable to get the Arabic data correctly.
Currently my code is as below,
public void ExportExcel(DataTable table, string filename)
{
if (table != null && filename != "")
{
HttpContext.Current.Response.Clear();
HttpContext.Current.Response.Buffer = true;
HttpContext.Current.Response.AddHeader("content-disposition", "attachment;attachment;filename=" + filename + ".xls");
HttpContext.Current.Response.Charset = "";
HttpContext.Current.Response.ContentType = "application/vnd.ms-excel";
System.IO.StringWriter stringWrite = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter htmlWrite =
new HtmlTextWriter(stringWrite);
GridView GrdExcel = new GridView();
GrdExcel.AllowPaging = false;
GrdExcel.DataSource = table;
GrdExcel.DataBind();
for (int i = 0; i < GrdExcel.Rows.Count; i++)
{
GridViewRow row = GrdExcel.Rows[i];
row.Attributes.Add("class", "text");
}
GrdExcel.RenderControl(htmlWrite);
string style = #"<style> .textmode { mso-number-format:\#; } </style>";
HttpContext.Current.Response.Write(style);
HttpContext.Current.Response.Output.Write(stringWrite.ToString());
HttpContext.Current.Response.Flush();
HttpContext.Current.Response.End();
}
}
EDIT 1:
Below is the final code which has worked for me
////If you want the option to open the Excel file without saving than
////comment out the line below
HttpContext.Current.Response.Cache.SetCacheability(HttpCacheability.NoCache);
HttpContext.Current.Response.Clear();
HttpContext.Current.Response.Buffer = true;
HttpContext.Current.Response.Charset = "UTF-8";
HttpContext.Current.Response.ContentEncoding = System.Text.Encoding.UTF8;
HttpContext.Current.Response.AddHeader("content-disposition", "attachment;attachment;filename=" + filename + ".xls");
HttpContext.Current.Response.ContentType = "application/vnd.ms-excel";
System.IO.StringWriter stringWrite = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter htmlWrite =
new HtmlTextWriter(stringWrite);
DataGrid grdExcel = new DataGrid();
grdExcel.AllowPaging = false;
grdExcel.DataSource = table;
grdExcel.DataBind();
foreach (DataGridItem i in grdExcel.Items)
{
foreach (TableCell tc in i.Cells)
tc.Attributes.Add("class", "text");
}
grdExcel.RenderControl(htmlWrite);
string style = #"<style> .text { mso-number-format:\#; } </style> ";
HttpContext.Current.Response.Write(style);
HttpContext.Current.Response.Write(stringWrite.ToString());
HttpContext.Current.Response.Flush();
HttpContext.Current.Response.End();
This was written by referring few articles from the web .Hope it helps

add this code to your code:
HttpContext.Current.Response.Charset = "UTF-8";
HttpContext.Current.Response.ContentEncoding = System.Text.Encoding.UTF8;

Every string wrap in Encoding.UTF8.GetString (for ex: Encoding.UTF8.GetString(str))
and in web.config:
<system.web>
<globalization requestEncoding="utf-8" responseEncoding="utf-8" culture="he-IL"/>
</system.web>
he-IL is in my case, write your language culture respectively

this is the code that i used to create the datagridview
public void maxdatatable()
{
string connectionString = "Data Source=.\\SQLEXPRESS;AttachDbFilename=C:\\inetpub\\wwwroot\\webradiation\\App_Data\\Radiation.mdf;Integrated Security=True;User Instance=True";
//Bind SQLDataSource to GridView for max data
// Create SQLDataSource.
SqlDataSource sqlDataSource1 = new SqlDataSource();
sqlDataSource1.ID = "SqlDataSource123";
this.Page.Controls.Add(sqlDataSource1);
// Bind ConnectionString to SQLDataSource.
sqlDataSource1.ConnectionString = connectionString;
// Retrieve records
sqlDataSource1.SelectCommand = "SELECT top 30 [date], [data] FROM [loc1] WHERE (([data] >= '2') AND (([date] >= '" + combdatetime11.ToString() + "') AND ([date] <= '" + combdatetime21.ToString() + "'))) ORDER BY [data] DESC, [date] DESC";
gridmaxdata.DataSource = sqlDataSource1;
gridmaxdata.DataBind();
}
public void currdata()
{
string connectionString = "Data Source=.\\SQLEXPRESS;AttachDbFilename=C:\\inetpub\\wwwroot\\webradiation\\App_Data\\Radiation.mdf;Integrated Security=True;User Instance=True";
// Create SQLDataSource.
SqlDataSource sqlDataSource2 = new SqlDataSource();
sqlDataSource2.ID = "SqlDataSource12";
this.Page.Controls.Add(sqlDataSource2);
// Bind ConnectionString to SQLDataSource.
sqlDataSource2.ConnectionString = connectionString;
// Retrieve records
sqlDataSource2.SelectCommand = "SELECT [date], [data] FROM [loc1] WHERE (([date] >= '" + combdatetime11.ToString() + "') AND ([date] < '" + combdatetime21.ToString() + "'))";
gridcurdata.DataSource = sqlDataSource2;
gridcurdata.DataBind();
}
for the word document, the output that i got is
(div) (/div)
*i have to used "(" and ")" to replace "<" and ">" because this pageweb make it disappear
the excel is like this
(style) .textmode { mso-number-format:\#; } (/style)(div)(div)
the pdf file i got an error saying that the document does not have pages.
do you not where did i do wrong?
you can create a extension function to convert the datasource datatable to excel and then send it to client using Response.WriteFile method
using OfficeOpenXml;
public static class Extensions
{
public static void ToExcel(this DataTable source, string destinationXlsxPath)
{
using (ExcelPackage pck = new ExcelPackage())
{
ExcelWorksheet ws = pck.Workbook.Worksheets.Add("Data");
ws.Cells["A1"].LoadFromDataTable(source, true);
FileInfo file = new FileInfo(destinationXlsxPath);
pck.SaveAs(file);
}
}
}

Passing a grid to a function used to export to excel

I have a method that is used to export the data to excel.Till now I have been passing table to the method.But now I wish to pass the grid data so that I do not have to call the procedures for different instances for getting different filtered data sets.
is there a way to do so?
public void ExportToExcel(DataSet ds)
{
if (ds.Tables[0].Rows.Count > 0)
{
string filename = ds.Tables[1].Rows[0]["filename"].ToString() + ".xls";
System.IO.StringWriter tw = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter hw = new System.Web.UI.HtmlTextWriter(tw);
DataGrid dgGrid = new DataGrid();
dgGrid.DataSource = ds.Tables[0];
dgGrid.DataBind();
//Get the HTML for the control.
dgGrid.RenderControl(hw);
//Write the HTML back to the browser.
//Response.ContentType = application/vnd.ms-excel;
Response.Clear();
Response.ClearHeaders();
Response.Charset = "";
Response.AddHeader("content-disposition", String.Concat("attachment;filename=", filename));
Response.AddHeader("Cache-Control", "max-age=0");
Response.ContentType = "application/vnd.xls";
// this.EnableViewState = false;
Response.Write(tw.ToString());
Response.End();
}
}
This is the method that I am using to export to excel.

Take a look at this awesome tool: http://www.carlosag.net/Tools/ExcelXmlWriter/
Futhermore, the author also created a code generator, which generates .net code from a provided excel sheet(formatting, layout and so on)
http://www.carlosag.net/Tools/ExcelXmlWriter/Generator.aspx
Here's some code that generates an excel file from a datatable (converted vb code, as pr. request by poster)
CarlosAg.ExcelXmlWriter.Workbook book = new CarlosAg.ExcelXmlWriter.Workbook();
book.ExcelWorkbook.ProtectWindows = false;
book.ExcelWorkbook.ProtectStructure = false;
var styles = book.Styles;
WorksheetStyle defaultStyle = styles.Add("Default");
var defStyles = defaultStyle;
defStyles.Name = "Normal";
defStyles.Font.FontName = "Calibri";
defStyles.Font.Size = 11;
defStyles.Font.Color = "#000000";
defStyles.Alignment.Vertical = StyleVerticalAlignment.Bottom;
Worksheet sheet = book.Worksheets.Add("Sheet1");
sheet.Table.DefaultRowHeight = 15f;
sheet.Table.FullColumns = 1;
sheet.Table.FullRows = 1;
DataTable dt = new DataTable(); //= your datatable
//Header
WorksheetRow HeaderRow = sheet.Table.Rows.Add();
foreach (DataColumn col in dt.Columns)
{
HeaderRow.Cells.Add(col.ColumnName.ToString());
}
//Body
foreach (DataRow dr in dt.Rows)
{
WorksheetRow row = sheet.Table.Rows.Add();
foreach (DataColumn cols in dt.Columns)
{
row.Cells.Add(dr[cols.ColumnName.ToString()].ToString());
}
}
sheet.Options.Selected = true;
sheet.Options.ProtectObjects = false;
sheet.Options.ProtectScenarios = false;
book.Save("path to file");
