Hi,
I have a Panel, with its Drag’nDrop behaviour defined as in the UploadFile example for the picturebox, here I am setting the Panel.BackgroundImage instead of PictureBox.Image. I start the application showing a not maximized Window in which I have the aforementioned panel. It works perfectly in Chrome, but in IE and Edge, the drag n drop is fired not only within the Panel borders, but anywhere in the window in which the panel is contained. And it sets the Panel’s background, as if the file had been dropped inside the Panel.
Best,
Alex
