求助，listview控件NM_CUSTOMDRAW中的CDDS_ITEMPREPAINT不响应

[marshallshenzhe]

代码如下:

INT_PTR CBatRegDlg::DialogProc(    HWND hDlg,
				   UINT uMsg,
				   WPARAM wParam,
				   LPARAM lParam
				)
{
switch(uMsg)
	{
		case WM_NOTIFY:
		{
			LPNMHDR nmh = (LPNMHDR) lParam;
			if(m_list == GetDlgItem(hDlg ,nmh->idFrom) && nmh->code == NM_CUSTOMDRAW)
			{
					NMLVCUSTOMDRAW* pLVCD = reinterpret_cast<NMLVCUSTOMDRAW*>( lParam);
					if ( CDDS_PREPAINT == pLVCD->nmcd.dwDrawStage )
					{
						return CDRF_NOTIFYITEMDRAW;//这里可以进来
					}
					else if ( CDDS_ITEMPREPAINT == pLVCD->nmcd.dwDrawStage )
					{

						COLORREF rText;	//这里从不进来
						crText = RGB(255,0,0);					
						pLVCD->clrText = crText;

						
						return CDRF_DODEFAULT;
					}
					return CDRF_DODEFAULT;
			}
		}
	}
}	

哪位高手能指点哈，先谢谢啦！！
