Answer 3

  OnEdited = DeTreeEdited
  OnEditing = DeTreeEditing
  OnFocusedColumnChanged = DeTreeFocusedColumnChanged
这几个事件中，应该有什么代码影响了。
比方说，被 cancel 了 或者 Handled 被设置成 true了。
单单是 cxTreeList的话，没有理由不能编辑的。或许我分析的不对，你可以这样检验。
代码复制一份备份。
然后，把cxTreeList 一个个事件中的代码清掉再运行一下。除了 单位 那一栏不敢肯定外，其他的肯定是可以编辑的。

Answer 4

我怀疑楼主 Tree关系 也就是数据绑定 有错了！
