Changing DragEffect when moving out of my form

I have a form which contains components that can be drag out my form to be on their own.

On the QueryContinueDrag event of my components, If the QueryContinueDragEventArgs.Action is Drop I test if my component is In the active form. If not, I create a new form and y put it in at the location of my cursor.

The problem is, the dragEffect indicates that I can't drop out the form. Is there any way I can change this?

Can't post much code here, cause it's way more complexe than just this. But if needed I'll try to do a simple project that show my issue.

According to Jimi:

You can change the Cursor while Dragging something.

Try this in QueryContinueDrag:

switch (e.Action)
{
    case DragAction.Continue:
        if (!this.Bounds.Contains(MousePosition))
            Cursor.Current = Cursors.Help;
        break;
    case DragAction.Drop:
        if (!this.Bounds.Contains(MousePosition))
        {
            // new Form
        }
        break;
}

You could do the same in GiveFeedback, checking the Cursor position, and set e.UseDefaultCursors = false; Cursor.Current = Cursors.Help; if the position falls outside the bounds, otherwise e.UseDefaultCursors = true;.
