Combobox - 如何将项目索引与记录ID匹配 [英] Combobox - How to match item index with record ID

问题描述

表A有2列：

recID int

recName字符串


我需要将所有recName加载到组合框B中使用B.Items.Add（recName）。这个

没问题。

但是，我希望能够将ComboxBox B'的索引与表A'
$ b $相匹配b recID，以便我可以使用B.SelectedIndex更新任何使用表的表格

A'的recID。目前，我必须使用笨拙的例程来查找recID来自

B.text

非常感谢任何帮助。

谢谢

Table A has 2 columns:
recID int
recName String

I need to load all recName into combobox B using B.Items.Add(recName). This
is no problem.
However, I would like to be able to match ComboxBox B''s index with table A''s
recID so that I can use B.SelectedIndex to update any table that uses Table
A''s recID. Currently, I have to use a clumsy routine to find recID from
B.text
Any help is greatly appreciated.
Thanks

推荐答案

从使用Items.Add更改为使用DataSource的方法和

DisplayMember - 这将允许您将更复杂的数据对象

绑定到ComboBox，同时保留其他（不可见）信息 -

DataView将允许你可以过滤原始数据，并且可绑定到一个

组合框（任何实现IList的类都是可绑定的）

Change from using Items.Add to a method that uses DataSource and
DisplayMember -- this will allow you to bind a more complex data object
to the ComboBox while maintaining other (non-visible) information -- a
DataView will allow you to filter the orginal data and is bindable to a
combobox (any class that implements IList is bindable)

我可以有一些示例代码可以查看吗？

谢谢
