How can I get the ContentType of the file on upload so that on download I can properly set the ContentType. I notice in your CustomFileProvider on the download page, that the line setting the content type on the Response object is commented. When downloading "uploadable documents", this causes the data to be displayed on the page and rather than IE treating it as a particular file type (.doc, .xls, etc).

 

Any thoughts?

Crickets? Where is the support?

Where do you want to get this? Are you storing the files into DB?

 

"Where do yout want to get this". That is essentially my question rather, where is it available to me? Yes I am storing files in the database. I need the ContentType at download time so I can properly send the correct ContentType to the browser.

 

There are two solutions I am familiar with:

 

1) Get and store the ContentType sent by the browser for the file on upload. Since upload is encapsulated in the CuteEditor control, the control would need to make the ContentType available at upload time.

 

2) Keep a "static" list of allowable content types and their extensions and use the appropriate ContentType at download time.

 

The ideal solution is 1, but I am having a hard time finding a place where the CuteEditor makes the ContentType available. 2 is doable but not ideal from a maintenance perspective.

 

 

 

 

1.

 

I need to check the code and get back to you as soon as possible.

 

2.

 

private string getContentTypefromFileName(string Filename)
 {
  if (Filename.IndexOf(".") == -1)
  {
   return "text/plain";
  }
  else
  {
   string extension = Filename.Substring(Filename.IndexOf("."));
   if (extension == ".exe")
    return "application/octet-stream";
   else if (extension == ".txt")
    return "text/plain";
   else if (extension == ".jpg")
    return "image/jpeg";
   else if (extension == ".gif")
    return "image/gif";
   else
    throw new NotSupportedException("Unknown extension");
  }
 }
