推荐答案

您不能在排序列表中更改项目的键.您必须删除现有项目，然后使用正确的密钥添加一个新项目.

好吧，在某些情况下可以间接更改它，但是由于不再对列表进行排序，因此它将破坏列表，并且操作假定列表如果进行了一些排序，您将得到未定义的结果.

或者，您可以使用列表而不是排序列表.

重命名项目时，是要它保留在当前位置还是要更新列表框项目的顺序?

You cannot change the key of an item in a sorted list. You have to remove existing item and add a new one with the proper key.

Well it would be possible to change it indirectly in some case but it would then broke the list since it would not be sorted anymore and operation assumes that the list if sorted some you would get undefined result.

Alternatively, you can use a list instead of a sorted list.

When you rename you item, do you want it to stay at the current location or you want to update listbox items order?
