问题 I have a container with different draggable -elements and there is a list of some "target" divs, where the user can drop the draggable elements.

问题 I want to drag and drop an image on wpf application form. Can anyone provide me the code and other links for that? 回答1: If you want to D&D within a single WPF application; then this code should get you going: Drag and Drop within WPF If you want to D&D between WPF applications, or between another non-WPF application you've got some options, but probably the easiest is to use a bitmap transfer (it takes a bit more code, so let me know and I'll publish it). 回答2: Does this drag and drop library
