How to do dynamic downloads links

Its probably not the correct title for asking this question as when I searched it gave results of dynamic urls for downloads. Thats not what I want... (at least I think it isn't)

My issue is that I need to dynamically create a list of, say newsletters as an example, the list gets created using loops in C# code and Response.Write(). The source is from a database that just contains the location source of the newsletter, date and name. Basic output of the code is:

|News Letters
|Date:       |Name:        |View button: |Download link:  |
|7/01/2013   |June News    |   [View]    |   [Download]   |
|8/01/2013   |July News    |   [View]    |   [Download]   |

more or less... The table is generated in a loop, so it can be any length.

How would I go about implementing a download for each individual news letter? The HTML code is just using an ordinary table and the view button is an href link to the souce.

If you're using HTML5 you can just add the word 'download' to the end of the href link.

<a href="link to newsletter.pdf" download>Download link</a>

this will force a download instead of opening the pdf like normal.

Good luck!

I'm not 100% on how you're trying to return the information but this will take a SqlDataReader and add each row in the data reader response to a new row in a table and build up a HTML string.

StringBuilder sb = new StringBuilder();
        sb.Append("<table><th>Date</th><th>Name</th><th>View</th><th>Download</th>");


        while (sqlDataReader.Read())
        {
            sb.Append(string.Format("<tr><td>{0}</td><td>{1}</td><td>{2}</td><td><a href='{3}' download>Download</a></td></tr>", sqlDataReader["Date"], sqlDataReader["Name"],
                          sqlDataReader["LocationSource"], sqlDataReader["LocationSource"]));
        }

        sb.Append("</table>");

        return sb.ToString();

I've made a slight adjustment, noticed I've put download inside the link tag. This is a HTML 5 feature that will force a download rather than opening in browser, more info here Force a browser to save file as after clicking link
