Hi All,

I have imported gridview data to a PDF but the problem is that I am unable to create a heading for the sheet through code

Below is the code:

C#

string attachment = "attachment; filename=Export.xls";
Response.ClearContent();
Response.AddHeader("content-disposition", attachment);
Response.ContentType = "application/vnd.ms-excel";
StringWriter sw = new StringWriter();
HtmlTextWriter htw = new HtmlTextWriter(sw);
// Create a form to contain the grid
HtmlForm frm = new HtmlForm();
GridView1.Parent.Controls.Add(frm);
frm.Attributes["runat"] = "server";
frm.Controls.Add(GridView1);
frm.RenderControl(htw);

//GridView1.RenderControl(htw);
Response.Write(sw.ToString());
Response.End();

My code is working 100% to output the excel sheet. Please tell me how to add a heading.
Thanks in Advance.

In short, you can't.

From your code it looks like you are delivering a spreadsheet to the user at runtime by responding to an HTTP request. You are doing so by setting the MIME Content-type header. This tells the client's browser what type of document to expect; in this case, Excel. This is the only document the client's browser expects, so the only way of adding a "header" would be to modify the spreadsheel and add a header to it before it is sent.

Another option would be to use iframes. The outer frame would container the header/title and the inner frame would link to your script above:

<html xmlns="http://www.w3.org/1999/xhtml" >
<head>
    <title>Report</title>
</head>
<body>
    <h1>Report of best songs of all time</h1>
    <!-- This should point to your script above. -->  
    <iframe src="excel_report.aspx" width="100%" height="300px">
       <p>Your browser does not support iframes.</p>
     </iframe>
</body>
