Response closes after export document

Question

I have been trying to export a Word document into Response using ASP.Net. So I achieved this goal with this code.

Response.Clear();
Response.ClearHeaders();
Response.ClearContent();
Response.ContentEncoding = Encoding.UTF8;
Response.Charset = "UTF-8";
Response.Buffer = true;

this.EnableViewState = false;
Response.ContentType = "application/msword";
Response.AddHeader("content-disposition", "attachment;filename=ExportedData" + Guid.NewGuid().ToString().Remove(5) + ".docx");

var wordData = this.RequestService.ExportToWord(this.RequestItem);

Response.BinaryWrite(wordData);
Response.Flush();

//Response.Clear();
//Response.End();
//Response.Close();
//RedirectToSamePage();
//Response.Flush();

But the problem is, when user export tha page as word document, the other functionality of the page disappears. Like, you can't click to another ASP control, because ending Response object, kills ASP controls connection with DLL. So, as you can see from the commented codes, I have been calling some Response object functions, but still I can't manage other ASP controls to work after Export operation. So, how can I manage that?

Thanks in advance.

Answer 1

You are getting this behaviour because you are altering the response object for current page. Because the page postback, the response object is used for rendering the latest page content which is now the Word binary content.

I will suggest that you do one of the below:

• Bring up a new page and implement the above code on the new page to push the Word document
• Have an iframe (you may not want to display it) and set the source to the page that will push the Word content. This will allow you to stay on current page without interfering with the flow.
