推荐答案

你需要将court_id从组合传递到数据库查询，并从那里获取法院名称。

you need to pass the court_id from the combo to the db query dunamically and from that fetch the court name.

您应该实现一个处理ComboBox点击事件的方法。

只要用户单击ComboBox，就会发生Click事件。

从那里你可以确定选择了哪个项目，你可以从数据库中检索法庭名称，并将法院名称放在文本框中。

You should implement a method that handles the ComboBox''s Click Event.
The Click event occurs whenever the user clicks ComboBox.
From there you can determine which item has been selected, you can retrieve the court name from the database, and put the court name in the text box.

非常感谢你的帮助..你可以给我任何代码样本PLZ
