I am implementing a drag&drop for items in a ClistCtrl, as per MFCDrag sample. Everything works fine until I change the style of my ClistCtrl to OwnerDraw. From that point on, the CreateDragImage function creates a drag image only for the icon and not for the text label. Where is the trick?

Commented:
The default wndproc for the list control can create the drag image for your items because it knows how to draw the text. But if your control is owner-drawn, then the default handler cannot possibly know how to draw your items. The only thing it does know how to draw is the icon (bitmaps). So you are in charge of drawing the drag items yourself. It isn't too hard because if you already have the ownerdrawn code, then you just need to create an imagelist and create the image you want to draw and use that image list for the dragging code.
