这一定很简单，但它打败了我。



如何手动加载第0行ComboBox显示和值成员，然后按照SQL查询第1行和第1行？



我正在尝试为构建SQL SELECT字符串提供ALL选项。



谢谢。

This has to be simple, but it's beating me.

How do I load row 0 ComboBox display and value members manually, then follow with an SQL query for rows 1 and on?

I'm trying to provide an "ALL" option for the construction of an SQL SELECT string.

Thank you.

John

It actually is pretty easy as you expect. There are different ways. You can add the option to your Data Source or you can just add it manually.
