Drag-and-drop event override C# GUI

Question

I have a drag-and-drop event handler registered to a parent form,

this.DragDrop += new DragEventHandler(Form_DragDrop);

There are several child form that are derived from the parent form. However, when I drag an item inside the forms, the action is only valid if there are no other components in that area.

I would like the drag-and-drop action to be valid in ALL areas of the form, including buttons, textboxes, etc. Is there anyway to specify some sort of overriding behavior inside the parents form?

Answer 1

You will have to implement the D+D events on all the controls. Not exactly practical, but you could do so by iterating the Form.Controls collection recursively. Give the user a good drop target, makes it easier for her to guess where to drop, easier for you to implement the code.
