Multi-Select List Box and Checked List Box[^]

询问者的要求如下:
1. 先尝试您要做什么！
2.制定看起来像问题/无法解决的问题.

尝试一下，告诉您是否遇到问题.

您要做的只是基于listbox1项选择的更改，使用与listbox1所选项相关的项填充listbox2.为此，您需要使用所选项目的唯一ID从数据库中检索相关数据.

Here is what is expected by enquirers:
1. TRY first what you want to do!
2. Formulate what was done by you that looks like an issue/not working.

Try them and tell if you face issues.

All you have to do is based on the listbox1 item selection change, populate listbox2 with the items related to listbox1 selected items. In order to get that, you would need to use the selected items unique id to retrieve the related data from database.
