Hi Team,

I would like to fire a validation post drag but pre-drop, this should allow me to cancel the drop and show a message to enduser explaining the cause.

the drop event only allows to modify the rendered alert dialog but it doesnt allow me to cancel the event altogether. 

any help is appriciated.

Regards,

Ashutosh

Hello Ashutosh,

As far as I understand from the provided information you need to cancel dropping a file based on a specific condition. If this is the case, you could prevent the dropping as demonstrated below: 

drop: function(e){             
              if(e.target == 'Documents'){               
                e.preventDefault()
              }
 },

Here is a Dojo example where the above is demonstrated. 

In case this is not the exact issue, please provide a little bit more details about the exact requirements, so I could understand the issue better and advise you further.
