Drag and Drop in WPF not working for DataFormats.FileDrop

I am developing WPF application, with severals drag and drop support.

In my application has several controls: listView_A, listView_B, and radioButtons.

my drag and drop works if I drag item from listView_A -> listView_B, listView_A -> radioButtons etc.

But I am unable to drag file from windows to all of开发者_开发问答 these controls (listview and radiobuttons), it just display a "no entry" cursor.

All of the controls has "AllowDrop" set to True.

I had tried all options I had, please help.

It is a known issue if you are using Windows Vista or Windows 7. Here is a similar question on StackOverflow:
