How can I remove the html content and add new string to the Response object. If I use the Respose.Write method the page contains the string, but while taking the view source option from browser it will display some html tag like Doctype, head, body etc. My requirement is only the string should be displayed in the source.

I am creating a web application that allows a user to download a csv file of a gridview. However, after looking at tutorials online such as http://www.aspsnippets.com/Articles/Export-GridView-To-Word-Excel-PDF-CSV-Formats-in-ASP.Net.aspxand such, I successfully got the table I wanted but there are HTML content appended to the table as well.There was also a similar problem being brought up on the forum,http://forums.asp.net/p/1528174/3692826.aspx. The solutions didn't help me much though. However, I am not really sure how Handlers can benefit this. Furthermore, I don't want the user to be navigated to a blank page just to download the csv file. I tried to debug and insert removal code to remove the html code before the response object is being wrote out but seems even at the end of the writing method, the response object seems to be holding just the table content only.
View 4 RepliesI'm getting this message when going to a web app that accesses my service.
"The content type text/html of the response message does not match the content type of the binding (text/xml; charset=utf-8)..."
The thing is, it happens once in a while even when no changes have been made to the service or the web app. And I can make it go away most of the time by going directly to the .svc?wsdl page in my browser and then coming back to the web app.
