You need to set the DragIcon property of whatever control you are dragging.  This way the icon you set will be shown when dragged.

I don't think that Windows Explorer "reproduces" the icons when you drag something.  If it does, than it does some nighty stuff with graphics manipulation, basically taking the "screen shot" of the item, then creating the icon on the fly.  You can try doing something like that, but I don't think it'll be easy - and definitely once you create this icos (with API calls of course), you won't be able to simply assign them to the DragIcon property of control.

sidjey- Are the icons always going to be changing or is there only going to be a few you will need to "Drag"? Because you could (if there were only going to be a few) just make up a bunch of icons and then have the cursor change to these icons when needed. I don't think I am doing a very good job of explaining so let me think about how to say it better. If you don't under stand just say.

It's ok for a listview but not for another control. I've a picturebox with a custom palette (createpalette). When I click on this picture, a small box appears with the color selected. I would like to drag this small box and the dragicon reproduce this small box with the same color. I don't know if it possible.
If you know how can i do this, please help me.
Thanks a lot

Prepare icons from advance. for all colors you have. just use them. it should be Graphical-dirty-job, nothing else.
