Question

I have a method in my C# codebehind that connects to SQL and creates a CSV file based upon the SQL data. This method is called when the user clicks a particular button on the website. I am trying to get this same method to also prompt the user to “open” or “save as” after the CSV file is generated.

I have tried the following:

System.Web.HttpResponse response = System.Web.HttpContext.Current.Response;
response.AddHeader("Content-Disposition", "attachment; filename=" + "C:\\temp\\report.csv" + ";");           
Response.TransmitFile("C:\\temp\\report.csv");

The user does get prompted to “open or save as”. In either case, the data in the CSV file also contains the entire source code of my Default.aspx. What do I need to do to my code to prevent that extra data from being appended onto my CSV? TIA…

You can call response.End() to prevent further processing by your page.
