    I'm getting quite used to working with your product, but one thing i'm still not capable of getting it done. I'm working on a project that is using a huge collection of AJAX and the scriptmanager. Since the scriptmanager doesn't really like the use of Respons, the SaveToHttpResponse is not working. Is there any other solution to create the effect that the user can download the file directly?
    Is it possible to push the savetoHttpResponse to a popup and download the data from there?
    Is it possible to save to stream and add the stream in my updatepanel so the download will be activated?
    A : We recommend that you can iframe to link a aspx page, so you can use savetoreponse methd to download file.

    We are thinking about purchasing this control, however we are planning on performing large data dumps into csv files using this control, we are looking at around 100k rows from a data table. Has anyone used this DataExport tool to dump this large of data into a file and if so how was the speed issue, canyou give an approximate time of how long it took?
    A : This is related to the performance test machines, spent mainly in the implementation of the writing on the document.

    When I try to export a DataTable containing a DateTime field to Excel, it is shown as a number. The number is a correct value when shown as DateTime, but the cell format should be DateTime instead of Default. The DataTable correctly contains the column as DateTime.
    Here is a code snippet that reproduces the issue:
    SqlCommand cmd = new SqlCommand();
cmd.Connection = new SqlConnection(/* Insert some SQL Server connection string */);
cmd.CommandText = "SELECT CAST('2010-01-01 0:00' AS DATETIME)";
cmd.CommandType = CommandType.Text;
SqlDataAdapter da = new SqlDataAdapter();
da.SelectCommand = cmd;
DataTable table = new DataTable();
da.Fill(table);
CellExport ce = new CellExport();
ce.DataTable = table;
ce.DataSource = Spire.DataExport.Common.ExportSource.DataTable;
ce.SaveToHttpResponse("test.xls", Response);
    The resulting Excel sheet contains the following data:
    Column1
    40179
    We consider purchasing Spire.DataExport, but I need to make this work... Please help.
    A : Please try to using following way, add GetDataParams event to Spire.DataExport. 
       private void cellExport1_GetDataParams(object sender, Spire.DataExport.EventArgs.DataParamsEventArgs e)
   {
                //e.sheet equals sheet index, e.col equals column index.

    Is it possible with your Controls to convert a xlsx files to a pdf with only printing and 128bit security.
    A : Yes, you can convert Excel File to PDF just need to do two steps:
    1. use OleDbConnection to open the Excel file as a DataSource
    2. use Spire.DataExport to export the data to a PDF file.
    The method following is a sample, the Excel file D:\temp\DatatableSample.xls is a test file in my computer. 
    static void ConvertExcelToPDF()
{
OleDbConnection conn = new OleDbConnection();
conn.ConnectionString
= @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=D:\temp\DatatableSample.xls;Extended Properties=""Excel 8.0""";

OleDbCommand command = new OleDbCommand();
command.CommandText = "select * from [country$A1:E19]";
command.Connection = conn;
conn.Open();

Spire.DataExport.PDF.PDFExport pdfExport1 = new Spire.DataExport.PDF.PDFExport();
pdfExport1.ActionAfterExport = Spire.DataExport.Common.ActionType.OpenView;
pdfExport1.DataFormats.CultureName = "en-US";
pdfExport1.DataFormats.Currency = "c";
pdfExport1.DataFormats.DateTime = "yyyy-M-d H:mm";
pdfExport1.DataFormats.Float = "g";
pdfExport1.DataFormats.Integer = "g";
pdfExport1.DataFormats.Time = "H:mm";
pdfExport1.FileName = Guid.NewGuid() + ".pdf";
pdfExport1.PDFOptions.DataFont.CustomFont = new System.Drawing.Font("Arial", 10F);
pdfExport1.PDFOptions.FooterFont.CustomFont = new System.Drawing.Font("Arial", 10F);
pdfExport1.PDFOptions.HeaderFont.CustomFont = new System.Drawing.Font("Arial", 10F);
pdfExport1.PDFOptions.PageOptions.Format = Spire.DataExport.PDF.PageFormat.User;
pdfExport1.PDFOptions.PageOptions.Height = 11.67;
pdfExport1.PDFOptions.PageOptions.MarginBottom = 0.78;
pdfExport1.PDFOptions.PageOptions.MarginLeft = 1.17;
pdfExport1.PDFOptions.PageOptions.MarginRight = 0.57;
pdfExport1.PDFOptions.PageOptions.MarginTop = 0.78;
pdfExport1.PDFOptions.PageOptions.Width = 10.25;
pdfExport1.PDFOptions.TitleFont.CustomFont = new System.Drawing.Font("Arial", 10F);
pdfExport1.SQLCommand = command; 

pdfExport1.SaveToFile();
}
    But the Spire.DataExport does not currently support the other 2 requirements 'only printing and 128bit security'.

    A : Sorry, dataexport does not support custom column header at present. You could use Spire.Doc, by which you can export you data to a document and convert it to pdf please check here to get more information about Spire.Doc.

    A : Yes, our free library supports it. Please check it on: Data Export Bar Chart for C#, VB.NET. Download Data Export library here.
    I learn that you can provide free data export library for downloading. I want to know if this library can export a large amount of data, for example, nearly 16000 columns.
    A : There is no column limitation of the free library. But, it will be limited by the file size. What's more, it supports only 65536 columns of Excel 2003.

    Yesterday, I used Spire.DataExport to export data from database, but I can't connect my database.
    Here I give you my code:

oleDbCommand.CommandText = this.txtCommandText.Text;

    I want to assign the data source of the DataGridView with the oleDbCommand, but I failed.
    The code:

    A : If you want to do so, you should use a data adapter, it like a intermediary of the command and DataGridView. You may use it with the following code: 
    OleDbDataAdapter da = new OleDbDataAdapter(oleDbCommand); 
DataTable dt = new DataTable();
da.Fill(dt);
dataGridView.DataSource = dt;

    I am using the DataExport and trying to build an XLS (Excel) with multiple workbooks/sheets (some people may call it tabs). I followed the following example from e-iceblue's own website.
    The example works great, if you are going to add a maximum of 3 workbooks. I am in need of having around 6. If I try to add a fourth workbook, I do not get an error but I also don't get the fourth workbook. I was thinking I might have an error in the fourth workbook, so I comment out the 3rd workbook's code and then I ran it again, the 4th workbook can now be seen (In workbook location #3)! Wow, so the fourth workbook has no errors! I uncommited the code for the 3rd workbook and bammm, the fourth workbook can't be seen again. Only the first 3 workbooks can be seen.
    There must be some sort of limitations on how many workbooks can be added?
    A : Sorry for any inconvenience caused by us. It looks like that your program worked on Spire.DataExport Community Edition. The maximum of 3 worksheets is a limitation. We also provide a Charged Edition of Spire.DataExport which can support up to 256 worksheets. You could get more information about the difference between them from the last table here. You could buy a license of Spire.DataExport Charged Edition from here.
