C# - Exporting Dataset To Excel File With Multiple Sheets?

Apr 2, 2010

In C# ASP.NET 3.5 web application, I need to export multiple datatables (or a dataset) to an Excel 2007 file with multiple sheets, and then provide the user with 'Open/Save' dialog box, WITHOUT saving the Excel file on the web server.

I have used Excel Interop before. I have been reading that it's not efficient and is not the best approach to achieve this and there are more ways to do it, 2 of them being: 1) Converting data in datatables to an XML string that Excel understands 2) Using OPEN XML SDK 2.0.

It looks like OPEN XML SDK 2.0 is better, please let me know. Are there any other ways to do it? I don't want to use any third-party tools.

If I use OPEN XML SDK, it creates an excel file, right? I don't want to save it on the (Windows 2003) server hard drive (I don't want to use Server.MapPath, these Excel files are dynamically created, and they are not required on the server, once client gets them). I directly want to prompt the user to open/save it. I know how to do it when the 'XML string' approach is used.

Exporting Multiple Tables In A DataSet To An Excel File With Multiple Sheets?

Jul 8, 2010

I was in need of exporting multiple tables in a DataSet to an Excel file with multiple sheets. I found a very good article in [URL].[URL] was able to successfully export each of my datatables in the dataset to excel worksheets. This solution worked for small number of rows. But when the data got larger I am consistently getting the system.outofmemoryexception. THis is because the code is using up the memory when creating excel.

Does anyone have another option to do the above?

Forms Data Controls :: Export Multiple Gridview To Excel Add Multiple Sheets

Oct 9, 2010

I create reports sometimes with a gridview and export the data to excel. Lets say I have like multiple gridviews and I wanted to export each gridview to excel under its own spreadsheet.

So gridview1, gridview2, gridview3 are exported to excel under $heet1, $heet2, $heet3.

I know how to export multiple gridviews to 1 excel sheet but I don't know how to export them separately under their own spreadsheet.

I've been researching online, and i'm continously searching, but does anyone know how to do what i'm trying to do with the gridview and excel or is this not possible?

C# - EXPORT Dataset To EXCEL

Feb 12, 2011

I am using the following code to export fields from a database table into excel. What I want to do is be able to write a SQL statement to retrieve fields from multiple tables and export them into excel. This code only allows me to export one table. Also, how can I display a save prompt dialog?

protected void export_Click(object sender, EventArgs e)
{
string sql = null;
string data = null;
string path = save_as.Text;
int i = 0;
int j = 0;
Excel.Application xlApp;
Excel.Workbook xlWorkBook;
Excel.Worksheet xlWorkSheet;
object misValue = System.Reflection.Missing.Value;
xlApp = new Excel.ApplicationClass();
xlWorkBook = xlApp.Workbooks.Add(misValue);
xlWorkSheet = (Excel.Worksheet)xlWorkBook.Worksheets.get_Item(1);
//connectionString = "data source=servername;initial catalog=databasename;user id=username;password=password;";
SqlConnection cnn = new SqlConnection(GetConnectionString());
cnn.Open();
sql = "SELECT Story, CreationDate FROM Story";
SqlDataAdapter dscmd = new SqlDataAdapter(sql, cnn);
DataSet ds = new DataSet();
dscmd.Fill(ds);
for (i = 0; i <= ds.Tables[0].Rows.Count - 1; i++)
{
for (j = 0; j <= ds.Tables[0].Columns.Count - 1; j++)
{
data = ds.Tables[0].Rows[i].ItemArray[j].ToString();
xlWorkSheet.Cells[i + 1, j + 1] = data;
}
}
xlWorkBook.SaveAs(path+".xls", Excel.XlFileFormat.xlWorkbookNormal, misValue, misValue, misValue, misValue, Excel.XlSaveAsAccessMode.xlExclusive, misValue, misValue, misValue, misValue, misValue);
xlWorkBook.Close(true, misValue, misValue);
xlApp.Quit();
releaseObject(xlWorkSheet);
releaseObject(xlWorkBook);
releaseObject(xlApp);

Web Forms :: Export A Big Dataset To Excel Via Web?

Feb 24, 2010

Actually I have a SQL query that a user exports to excel in our web server. I did it in c# with Visual Studio 2003 (.Net v1.1): I get the data from a SQL server into a Dataset, then with this method I create the XLS file:

private void ExportAsExcelFile ( DataSet dtExport )
{
Response.Clear() ;
Response.ContentType = "application/vnd.ms-excel";
Response.ContentEncoding = System.Text.Encoding.UTF8 ;
Response.Charset = string.Empty ;
Response.AddHeader ( "Content-Disposition", "attachment;filename=data.xls" ) ;
System.IO.StringWriter objStringWriter = new StringWriter () ;
System.Web.UI.HtmlTextWriter objHtmlTextWriter = new System.Web.UI.HtmlTextWriter(objStringWriter) ;
DataGrid objDatagrid = new DataGrid () ;
objDatagrid.DataSource = dtExport ;
objDatagrid.DataBind () ;
objDatagrid.RenderControl ( objHtmlTextWriter ) ;
Response.Write (objStringWriter.ToString()) ;
Response.End () ;
}

Well, this works when the SQL query has 10.000 rows and so on. But now the query has more than 200.000 rows, and Im getting a TimeOut Error trying to export the data. I read about generate this big files with a Store Procedure and the SQL Commad: BCP [URL], but I tryed and it fails. I have no permissions to execute this command. Is there any other way to export this SQL data to Excel via a ASPX page?

VS 2008 - Export Dataset To Excel Attachment

Jul 12, 2012

I need to give users of my asp.net/vb.net web application the ability to click a button which will then send them an e-mail with the contents of a SQL query attached as an Excel e-mail attachment.

I can manage all of this apart from getting the contents of a VB dataset object into an Excel file on my server.

I know how to export a gridview to Excel at the client end, but my boss has been adamant that he wants the button to send an e-mail with the results attached - I have no need to display a gridview at all.

How to export the contents of a datareader or dataset directly into an Excel file at the server side?
