启用CListCtrl选取框选择

Question

我在报告模式下使用MFC CListCtrl并通过

启用全行选择和alpha混合选取框选择

const DWORD extendedStyle = m_wndList.GetExtendedStyle();
m_wndList.SetExtendedStyle(extendedStyle | LVS_EX_DOUBLEBUFFER | LVS_EX_FULLROWSELECT);

选择框选择，即在按住鼠标左键的情况下跨多个项目选择矩形，如果我在CListCtrl窗口的未被项目占用的区域中开始选择，则可以正常工作。

但是，如果我单击某个项目并想从那里开始选择框，则不会创建选择矩形。这与例如Windows资源管理器形成对比，在该资源管理器中，如果从所选项目启动，则选取框选择也有效。

作为MCVE，我在Visual Studio 2017上使用了“新建项目向导”并创建了基于对话框的MFC应用程序，并在对话框资源上放置了“列表控件”。此列表控件通过DDX连接到成员变量CListCtrl m_wndList，并获得如上所述的扩展样式。

   return TRUE;
}

有人能指出我正确的方向并解释，如何启用从列表控件中的单个项目开始的选取框选择？
