Now when I am selecting customer from dropdown i want CustomerLastName for some other operation.
So how can access CustomerLastName using ASP.Net and C#

推荐答案

当CustomerID是唯一的时，您可以通过CustomerID获取CustomerLastName。

您最终如何做到这一点取决于您如何存储数据，您能否提供有关您正在使用的数据库系统的详细信息？或者您使用文件来存储客户？

When the CustomerID is unique you can get the CustomerLastName by the CustomerID.
How you do that in the end depends on how you store the data, can you give me details about the database system you are using? Or are you using a file to store the customers?
