如何更新父/子关系信息？ [英] How to UPDATE parent / child relation information?

问题描述

我想问一下是否有人可以帮助我了解如何更新我的孩子关系。我有一个客户表，然后是帐户表，帐户是孩子。我可以成功地将信息保存到客户表：



me.validate（）

me.CustomersBindingSource.Endedit（）

me.CustomersAccountsBindingSource.Endedit（）孩子

me.TableAdapterManager1.UpdateAll（me.Shopdataset）



我不喜欢在运行程序时，我的datagridviews上显示的信息有问题。在关闭程序然后重新启动程序后，我可以看到我的客户数据存在，但所有客户的帐户数据都丢失了。



提前谢谢。



我尝试了什么：



我试过更新全部绑定源。我还尝试添加绑定导航器并使用保存按钮插入标准工具，并尝试使用保存按钮进行保存。

I would like to ask if someone could please help me to understand how to update the child relation that I have. I have a "customers" table and then "accounts" table and the accounts is the child. I can successfully save information to the customers table:

me.validate()
me.CustomersBindingSource.Endedit()
me.CustomersAccountsBindingSource.Endedit() "child"
me.TableAdapterManager1.UpdateAll(me.Shopdataset)

I don't have an issue displaying the information on my datagridviews when I am running the program. After I have closed the program and then restarted the program, I can see that I customers data is there but all the customer's account data is missing.

Thank you in advance.

What I have tried:

I have tried updating all of the binding sources. I have also tried to add a binding navigator and inserted the standard tools with the save button, and tried using the save button to save.
