重载DrawItem, 在传入的item 的dc设置颜色.或者用custom draw.作起来不是一两个语句的, www.codeguru.com 有例子, 自己找.

不错。好像是 XP style 的 ListCtrl

看一下codeproject上的XListCtrl例子，写的非常清楚

http://www.codeproject.com/listctrl/lvcustomdraw.asp
主要响应自绘事件

怎样让ListCtrl的颜色相间原文地址：http://hao.kjz.cn/xml/04080207071562.xml　　看到上图的ListView没有？怎样才能使列表控件每一行的颜色都不相同？其实是通过处理NM_CUSTOMDRAW，可以实现这个的功能！但是NM_CUSTOMDRAW在Class Wizard中有可能看不到啊！？不用管它，直接按照下面的方法添加处理过程即可！1. 在消息映射表中加入如下代码BEGIN_MESSAGE_MAP(CIHISSERVERView, CListView)
//……
ON_NOTIFY_REFLECT(NM_CUSTOMDRAW, OnCustomDraw)
//……
END_MESSAGE_MAP()
2.在.h头文件中加入：  afx_msg void OnCustomDraw(NMHDR*, LRESULT*);
3.在.cpp文件中重载NM_CUSTOMDRAW：void CMyView::OnCustomDraw(NMHDR* pNMHDR, LRESULT* pResult)
{
      // TODO: 在此添加消息处理程序代码
      // Contains information specific to an NM_CUSTOMDRAW
      // notification message sent by a list-view control.
      // mean:draw each item.set txt color,bkcolor....
      NMLVCUSTOMDRAW* pLVCD = (NMLVCUSTOMDRAW*)(pNMHDR);      // Take the default processing unless we set this to something else below.
      *pResult = CDRF_NEWFONT;      // First thing - check the draw stage. If it's the control's prepaint
      // stage, then tell Windows we want messages for every item.
      if ( pLVCD->nmcd.dwDrawStage==CDDS_PREPAINT)
      {
            *pResult = CDRF_NOTIFYITEMDRAW;
      }
      // This is the notification message for an item.  We'll request
      // notifications before each subitem's prepaint stage.
      else if ( pLVCD->nmcd.dwDrawStage==CDDS_ITEMPREPAINT )
      {
            COLORREF   m_crTextBk , m_clrText;
            int nItem = static_cast<int> (pLVCD->nmcd.dwItemSpec);

            CListCtrl &m_list = GetListCtrl();
            CString str1 = m_list.GetItemText(nItem ,15);

            bool bDBImplFail = false ;
            if (pLVCD->nmcd.dwItemSpec%2==0)
            {
                  m_crTextBk = RGB(253,241,249) ;
                  m_clrText  = RGB(0,0,0) ;
            }
            else
            {
                  m_crTextBk =  RGB(51,153,255);
                  m_clrText  =  RGB(0,0,0);
            }

            pLVCD->clrTextBk = m_crTextBk;
            pLVCD->clrText = m_clrText;
            *pResult = CDRF_DODEFAULT;
      }
}

//test6dlg.h
afx_msg void OnCustomdrawMyList ( NMHDR* pNMHDR, LRESULT* pResult );//testdlg.cpp
BEGIN_MESSAGE_MAP(CTest6Dlg, CDialog)
//{{AFX_MSG_MAP(CTest6Dlg)
ON_WM_SYSCOMMAND()
ON_WM_PAINT()
ON_WM_QUERYDRAGICON()
//}}AFX_MSG_MAP
ON_NOTIFY ( NM_CUSTOMDRAW, IDC_LISTCTRL, OnCustomdrawMyList )
END_MESSAGE_MAP()void CTest6Dlg::OnCustomdrawMyList ( NMHDR* pNMHDR, LRESULT* pResult )
{
NMLVCUSTOMDRAW* pLVCD = reinterpret_cast<NMLVCUSTOMDRAW*>( pNMHDR );

*pResult = CDRF_DODEFAULT; if ( CDDS_PREPAINT == pLVCD->nmcd.dwDrawStage )
{
*pResult = CDRF_NOTIFYITEMDRAW;
}
else
if ( CDDS_ITEMPREPAINT == pLVCD->nmcd.dwDrawStage )
{
*pResult = CDRF_NOTIFYSUBITEMDRAW;
}
else
if ( (CDDS_ITEMPREPAINT | CDDS_SUBITEM) == pLVCD->nmcd.dwDrawStage )
{
COLORREF clrNewTextColor, clrNewBkColor;
int nItem = static_cast<int>( pLVCD->nmcd.dwItemSpec );

if( (m_nSubItem == pLVCD->iSubItem))
{
clrNewTextColor = RGB(255,0,0);
clrNewBkColor = RGB(255,255,0);
}
else
{
clrNewTextColor = RGB(0,0,0);
clrNewBkColor = RGB(255,255,255);
}

pLVCD->clrText = clrNewTextColor;
pLVCD->clrTextBk = clrNewBkColor;

*pResult = CDRF_DODEFAULT;
}
}m_nSubItem就是需要改变的行请在找到你需要改变的l列后调用
m_List.RedrawItems(0, m_List.GetItemCount());

我发现手头有个coloredlistctrl工程。运行后列表框可以随意设置任何一格或者一列或者一行的颜色，要不？
