富文本框 [英] Richtextbox

问题描述

我在表中有一个描述"列和一个类别代码"列.我已经在列表框中填充了描述".我想要的是，当我单击列表框中的描述"时，richtextbox应该填充描述"值的相关"categoryCode"，并且该值应该在richtext框中拉出.

两列都在同一表中.
例如:我的富文本框应显示为..

CategoryCode = ??????????

请给我一些想法.

I have a "Description" column and a "categoryCode" column in a table. I have populated the "Description" in a listbox. What I want is that when I click the "Description" in listbox, the richtextbox should populate the related "categoryCode" of the "Description" value and the value should be pulled in richtext box.

Both columns are in same table.
Ex: My rich text box should appear as..

CategoryCode = ??????????

Please give me some ideas.
