Can not get c # to make downloadable csv

I need to encode a button that, onclick, downloads a csv file to a client computer (this is a web application)

So, some kind of research, pulled out all the lines together, go with the number, not working.

I am trying to get this now:

    protected void btnDownload_onClick(object sender, EventArgs e)
    {
        Response.Clear(); 
        Response.AddHeader("content-disposition", "attachment; filename=tmp.csv");
        Response.ContentType = "text/csv";
        Response.Write("one,two,three,four,five");
        Response.End();
    }

according to the blog that appeared on google that all i need is to get that csv download it.

it doesn’t work, and I can’t understand what is wrong with him.

1) firebug inspection: the answer is EMPTY.
2) VS Debugging, strangely stops after a line Response.End()and complaints that she cannot find the content.

Am I missing something? Many thanks. highly.
