Here i am exporting the datatables in a dataset to excel.How to make the header font of the datatable alone look bold.Here is my code
HttpContext.Current.Response.Clear();
HttpContext.Current.Response.AddHeader("content-disposition", "attachment;filename=" + fileName + "");
HttpContext.Current.Response.ContentType = "application/vnd.ms-excel";
StringWriter stringWriter = new StringWriter();
HtmlTextWriter htmlWrite = new HtmlTextWriter(stringWriter);
DataGrid dataExportExcel = new DataGrid();
foreach (DataTable table in dtInputParameters.Tables)
{
dataExportExcel.DataSource = table;
dataExportExcel.DataBind();
dataExportExcel.RenderControl(htmlWrite);
htmlWrite.WriteLine("<br/>");
// htmlWrite.AddStyleAttribute(System.Web.UI.HtmlTextWriterStyle.FontWeight, "bold");
}
StringBuilder sbResponseString = new StringBuilder();
sbResponseString.Append("<html xmlns:v=\"urn:schemas-microsoft-com:vml\" xmlns:o=\"urn:schemas-microsoft-com:office:office\" xmlns:x=\"urn:schemas-microsoft-com:office:excel\" xmlns=\"http://www.w3.org/TR/REC-html40\"> <head><meta http-equiv=\"Content-Type\" content=\"text/html;charset=windows-1252\"><!--[if gte mso 9]><xml><x:ExcelWorkbook><x:ExcelWorksheets><x:ExcelWorksheet><x:Name>" + worksheetName + "</x:Name><x:WorksheetOptions><x:Panes></x:Panes></x:WorksheetOptions></x:ExcelWorksheet></x:ExcelWorksheets></x:ExcelWorkbook></xml><![endif]--></head> <body>");
sbResponseString.Append(stringWriter + "<table width='800' height='100' align='center' style='text-align:center'");
sbResponseString.Append("</table></body></html>");
HttpContext.Current.Response.Write(sbResponseString.ToString());
HttpContext.Current.Response.End();
Any suggestion?

To use the Bold, Italic, and Underline commands: Select the cell(s) you want to modify. Click the Bold (B), Italic (I), or Underline (U) command on the Home tab. In our example, we'll make the selected cells bold. The selected style will be applied to the text.
It is possible to generate Excel exports with some static images or text in the Excel's headers. The steps are: Start with a new or existing Excel template and click on Insert menu and there click on Header & Footer submenu. This adds Header & Footer to your Excel document.
You must pass value of row 0 so that first row of your excel sheets have column headers with bold font size. Just change DataColumnCollection to your columns name and change col. Caption to specific column name. You may do this to cell of excel sheet you want bold.
The CTRL+B key is used to apply or remove bold. It will bold or un-bold the cell when one or more cell is selected. This shortcut works for the new text you type after using it, or you can highlight existing text and then bold it via the shortcut.
You need to set the HeaderStyle on the DataGrid to use bold font. That's all.
dataExportExcel.HeaderStyle.Font.Bold=true;
Cursor.Current = Cursors.WaitCursor;

worksheet1.Cells[1, i] = GrdViewData.Columns[i - 1].HeaderText;
worksheet1.Cells[1, i].Font.Bold = true;
}
