与SplitContainer混淆 [英] Confused with SplitContainer

问题描述

大家好：

我正在开发一个与SQL Server接口的GUI。

I am developing a GUI to interface with SQL Server.

在我的表单上我有一个SplitContainer水平方向。顶部面板 - Panel1有一个ComboBox，用于选择要访问的SQL Server。两个TextBoxes;一个用于LogIn，另一个用于密码。两个按钮;一个连接到服务器，
另一个退出应用程序。另一个ComboBox用于选择您要使用的数据库。

On my form I have a SplitContainer in Horizontal orientation. The top panel - Panel1 has a ComboBox for selecting the SQL Server you want to access. Two TextBoxes; one for LogIn and the other for the password. Two buttons; one to connect to the server and the other to exit the application. The other ComboBox is for selecting the database you want to use.

底部面板 - Panel2包含一个TabControl，每个标签页都是特定表的GUI。 

The bottom panel - Panel2 contains a TabControl and each tab page is a GUI for a specific table. 

这是我的地方我遇到了问题。完成登录服务器并指定要使用的数据库后。我需要在标签页
Customers上绑定控件。 我不知道将代码放入哪个事件，因此我可以使用BindingSource将控件绑定到导航器。

This is where I am having my problem. After I have finished logging into the server and specifying the database to use. I need to bind the Controls on the tab page Customers. I don't know which event to place the code into so I can bind the controls to the navigator using a BindingSource.

提前致谢，

推荐答案

我认为你应该处理
"Database："组合框的SelectedIndexChanged 。使用字段的当前值来访问数据并绑定选项卡的控件，除非缺少某些值。

I think that you should handle the SelectedIndexChanged of "Database:" combobox. Use the current values of the fields to access the data and bind the controls of the tabs, unless some of the values are missing.

此外，可能会处理其他事件，例如
< "服务器名称："的em> SelectedIndexChanged ，它应该可以清除绑定和选项卡。

Also, maybe handle other events, such as the SelectedIndexChanged of "Server Name:", which should probably clear bindings and the tabs.
