推荐答案

您不应该尝试传递数据 - 表单应该询问它对数据的控制在您的示例中属性，但控件应该告诉通过活动获得数据的表格。



看看这个：在两种形式之间传递信息，第2部分：儿童到父母 [ ^ ] - 它在C＃中，但想法完全一样。

You shouldn't try to pass data up - the form should ask it's controls for the data via properties as in your example, but the control should "tell" the form that data is available via an event.

Have a look at this: Transferring information between two forms, Part 2: Child to Parent[^] - it's in C# but the idea is exactly the same.

检查这些：

父Windows窗体和子用户控件传递数据 [ ^ ]

传递变量从子到父，像函数VB.N ET [ ^ ]

Check these:
Parent Windows Form and Child UserControl Passing Data[^]
Pass variable From child to parent, Like a Function VB.NET[^]
