Response.Write and UpdatePanel

Question

I generate a vcard that I send to the client using the following code snippet:

Response.AddHeader(\"Content-Disposition\", string.Format(\"attachment; filena         


        

Answer 1

Why don't you consider the use of a separate handler/page to serve the vcard?

This is maybe the easiest and cleaner way to do that and it doesnt interfere any other (async or not) postback related to the updatepanel.
