  Hello Telerik Team,
  
  I have one issue with radasyncupload control. I need to trap event when user clicks on cancel button during uploading of a file. I didn't find any onclient method which could allow this.
  
  Do you have an idea, how to solve it ?
  
  For further information please check the attachment of this message.
  
  Thank you.

  Hello Vasssek,
  
  There is no event which is fired when this "cancel" button is clicked, but you could subscribe on the "click" event and put your logic into the event handler function. In order to subscribe on the click event use the following implementation:
  

  function pageLoad() {

   

      var upload = $find("RadAsyncUpload");

   

      $telerik.$(".ruCancel", upload.get_element()).live('click', function() {

   

          alert('User clicked on cancel');

   

      });

  }

  
   I hope you will find this approach useful.
  
  All the best,

  That is a nice way to handle the cancel event. Can you tell me how, client-side, I can then reset the AsynchUpload control back to the "select a file" mode?
  
  Thanks.

  Hello Mike,
  
  If you want to delete the input with the canceled file you should get a reference to the RadAsyncUpload and then call its deleteFileInputAt  method:
  

  async.deleteFileInputAt(0)
