问题描述

亲爱的所有人

我有一个列表框控件，其中的数据来自表States.表只有一列.数据以这种方式存储

Dear All

I have a listbox control in which data comes from table States . Table has only one column . Data is stored like this

PB
HR
CHD

现在，在列表框控件的窗体中，它将显示所有这4条记录.我希望除了这些Listbox控件之外，ListBox控件的末尾应显示"New"，当用户单击"New"时，它应打开"New States创建"的形式并允许添加新State，然后更新列表框.如何使用C#?

谢谢

I want in addition to these Listbox control should display "New" at the end in ListBox , when user click on New it should open a form of New States creation and allow to add a new State , and then update the list box. How is it possible using C#?

Thanks

推荐答案

只需使用UNION子句在源查询中添加带有新建"的行.

Just add a row to the source query with ''New'' by using a UNION clause.

是否可以将控件放置在按钮或文本框类型的列表框下面?您甚至可以创建自己的用户控件，将这两个控件组合在一起以进行格式化.无论如何，这就是我的意愿.

Can you just position a control under the listbox, of type button or textbox? You could even create your own user control that combines these 2 for formatting purposes. This is how I would to it anyhow.
