我想以编程方式在tabpage上构建按钮，并且我希望保留应用程序上的所有按钮以在每次登录时使用它。 此按钮名称应来自数据库项目表。

推荐答案

您好，

以下从SQL-Server数据库表中读取的信息创建按钮，并显示如何使用click按钮的事件。

The following creates button from information read from a SQL-Server database table and shows how to work with click events for the buttons.

警告，我没有使用TabControl但你应该能够使用所呈现的内容来实现这一点。例如，如果按钮需要位于特定选项卡上，则需要在表中添加一个字段，该字段按名称或索引指定选项卡。如果这是一个不同的数据库，例如Oracle或MS-Access当然需要更改基础SQL和数据提供程序，例如从SqlClient说OleDb等。如果你已经指出数据库，我仍然会把它作为工作的蓝图。

Caveat, I'm not using a TabControl yet you should be able to work with what is presented to achieve this. For example, if buttons need to be on specific tabs you would need to add a field in the table that specifies the tab by name or by index. If this is a different database e.g. Oracle or MS-Access you would of course need to change the underlying SQL and data provider e.g. from SqlClient to say OleDb etc. If you had indicated the database I still would had presented this as a blueprint to work from.

我的MSDN代码示例 从SQL-Server数据库动态创建窗体表单按钮。在这种情况下，该表来自Microsoft NorthWind。

My MSDN code sampleDynamically create window form buttons from a SQL-Server database. In this case the table is from Microsoft NorthWind.

响应点击事件（我显示一个新窗口，但你可以做任何你想做的事）
