推荐答案

我会尝试通过执行以下任一操作来实现此目标

-对各种DragXXXX事件做出反应，并在得到DragDrop事件时，重新绘制该行.

或

-对控件的MouseDown，MouseMove，MouseUp和Move事件的组合做出反应，并在适当时重画该行.

I would try accomplishing this by doing one of the following

- React to the various DragXXXX events, and when you get the DragDrop event, redraw the line.

OR

- React to a combination of MouseDown, MouseMove, MouseUp, and Move events for the control, and when the redraw the line as appropriate.
