推荐答案

如果您创建了两个用户控件，则需要在类定义中将GenerateMember指定为公共对象，例如

< pre>
公共子GenerateMember()
''''您的代码
结束子
</pre>

如果您因此继承使明细成为master的子代，则应将sub声明为protected.

< pre>
受保护的子GenerateMember()
''''您的代码
结束子
</pre>

If you created the two user controls, then in the class definition you need to specify the GenerateMember as public e.g.

<pre>
Public Sub GenerateMember()
''''Your code
End Sub
</pre>

If you inherit therefore making details a child of master, you should declare the sub as protected.

<pre>
Protected Sub GenerateMember()
''''Your code
End Sub
</pre>
