In My ViewModel class I have a property:

class ViewModel
{
public string FileName {get;set;}
}

and in my View I bind a label's content to ViewModel's FileName.

now When I do drag-drop a file to my View, How can I update the label's Content property, so that the ViewMode's FileName also get updated via binding?

Directly set the label's Content property won't work, it just simply clear the binding.
