Simply Notes #2: Single Click File Upload in ASP.Net

For those who hate to click more than required and like Scott Hanselman said 

"There are a finite number of keystrokes left in your hands before you die.

I definitely have very little left to spare and I am still writing this! - Check yours

Here is one way of doing file upload in single click

  1. Keep fileupload control hidden using css styles
  2. On client click of the upload link button trigger the fileupload click event and return false so that server side click event is not fired
  3. Now bind an onchange event for the fileupload control
  4. Onchange event trigger the server side click event of upload link button
  5. On upload link server click save the file on server
