<P align=left>如上代码，这是一个可多选的ListBox，并拥有一个右键上下文菜单。</P>
<P align=left>WPF里让ListBox支持通过右键选取或取消选取项。</P>
<P align=left>现在的问题是，我点右键的时候会显示出右键菜单，并且同时改变了我鼠标所在位置的项的选择状态。</P>
<P align=left>比如我想挑选3项，然后通过菜单将其删除，但是用右键打开菜单时就会改变我的选择状态，比如取消了一个已选择的项。</P>
<P align=left>怎么才能禁用右键选取功能？</P>
<P align=left>或者什么方法才能拦截ListBoxItem的右键点击事件？</P></SPAN></DIV>
