C# 要实现ListView的各行各列重绘是一件很麻烦的事情，最近就确定要实现一个功能需求，在一个ListView各行的第二列（Details模式）加入一个小图标。之前已经领教过ListView的设置，要开启重绘ListView各行，就必须重载它的OnDrawSubItem，但是ListView默认是不会执行你重载的OnDrawSubItem事件的，除非你把它OwnerDraw设置为true，即打开由用户控制绘图模式。然而让人抓狂的是，OwnerDraw=true后，整个ListView的Item/SubItem/Column全部都会空掉，即使你同时重载OnDrawSubItem/OnDrawItem/OnDrawColumnHeader并执行里面的base.OnDrawXXXXX(e)，也不给你画出来。,C# to achieve the ListView to redraw the lines of the columns is a very troublesome thing, recently determined to achieve a functional requirements, each row in a ListView in the second column (Details mode) by adding a small icon. Had previously experienced the ListView settings, to open the ListView redraw the lines, you must override it OnDrawSubItem, but the ListView by default will not be implemented overloaded OnDrawSubItem your event, unless you put it OwnerDraw is set to true, that is open from user-controlled graphics mode. But people crazy is that, OwnerDraw = true, the entire ListView' s Item/SubItem/Column will all be empty out, even if you also overload OnDrawSubItem/OnDrawItem/OnDrawColumnHeader and perform inside base.OnDrawXXXXX (e), not given you have drawn.
