Hi Expert,

I am developing website in asp.net.with my sql as database.
I am exporting datatable results in excel sheet.

I am fetching results from 2 table - one in inquiry and other is inquiry_event_assigned

inquiry table contains details information regarding inquiry.
In inquiry form there is multiple event selection option.
These events are stored in inquiry_event_assigned table.
This table contains (inquiry_event_id,inquiry_id,event_id) .

I am using following method to generate excel

protected void ExportToExcel(DataTable dt)
    {
        try{
        if (dt.Rows.Count > 0)
        {

            string filename = "Inquiry Reports.xls";

            string excelHeader = "Inquiry Report";

            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 = dt;
            dgGrid.BorderStyle = BorderStyle.None;

            dgGrid.DataBind();

            // Report Header

            hw.WriteLine("<b><u><font size=’3′> " + excelHeader + " </font></u></b>");

            //Get the HTML for the control.

            dgGrid.RenderControl(hw);

            //Write the HTML back to the browser.

            //Response.ContentType = "application/vnd.ms-excel";

            Response.ContentType = "application/vnd.ms-excel";

            Response.AppendHeader("Content-Disposition", "attachment; filename=" + filename + "");

            this.EnableViewState = false;

            Response.Write(tw.ToString());

            Response.End();
            }
           }
            catch(Exception ex1)
            {
            }
    

        }

It export all the results in excel sheet one by one,means if perticuler inquiry associated with multiple events exports one after another.

If there is more than one events associted with perticuler inquiry they must be in single cell with comma separated.

Try this

Response.Clear();
Response.AddHeader("content-disposition", "attachment;filename=FileName.xls");
Response.Charset = "";
Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.ContentType = "application/vnd.xls";

System.IO.StringWriter stringWrite = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter htmlWrite = new HtmlTextWriter(stringWrite);

myDataGrid.RenderControl(htmlWrite);
Response.Write(stringWrite.ToString());
Response.End();
