I need to implement the answer provided to the following StackOverflow thread: How to receive drag move and drag drop events using CefSharp winforms

I've tried implementing the code, but I feel the answer provided does not give me enough detail about the code provided.

For instance, why does IOleDropTarget and IOleDropTargetHelper exist?

Why in the example usage of the OleDragEnter procedure, does it RaiseEvent to the Browsers DragEnter -- RaiseEvent DBDragEnter(eff, New Point(winPT.x, winPT.y)), when we removed it in the EnumChildProc_Browser -- Dim ret = NativeMethodsEx.RevokeDragDrop(hwndChild)

My implementation doesn't work because I receive an error when attempting to remove the drag and drop

You can find my code at my github repo : https://github.com/krptodr/StackOverflow.git

I expect to be able to see how to override the default DragHandler for cefSharp winForms, using the code provided from the above referenced solution.

Remove the `` attribute from your DragDropHelper class. – Hans Passant May 16 '19 at 18:53
Thank you, I was able to resolve that but I'm still having trouble getting a working solution. – Krptodr May 16 '19 at 18:57
@HansPassant My example is nearly working. I can override the browsers Drag and Drop, but my new drag and drop handler is not grabbing the appropriate data for the IDataObject. – Krptodr May 16 '19 at 21:38
