Thanks Eric, but, I forgot to mention in my previous post, I set this property.
Actually in the new() event just after the InitializeComponent() call.
Even adding allowdrop=true in the load() doesn't work, have you other suggestions?
Keep in mind that the DragEnter, DragLeave, ecc. works!!

>You need to set the AllowDrop property of the PictureBox to True. But this property doesn't show into the properties dialog. The simplest workaround is to set them into the Load event:

PictureBox1.AllowDrop = True
