推荐答案

试图跋涉这是痛苦的！请将来考虑使用至少一些标点符号...如果可以的话;请阅读您的问题，我们无法回答。 ：笑：



所以，你有两种形式：

Trying to wade through that is painful! Please, in future, consider using at least some punctuation...if we can;t read your question, we can't answer it. :laugh:

So, you have two forms:

Form1
   Radio button 
   Combobox

Form2
   Textbox
   DataGridView
   ButtonOne
   ButtonTwo
   OKButton

当用户在Form1中检查RadioButton时显示Form2。

您在DataGridView中输入数据并按OK。此时，您希望将信息从DataGridView传输到Form1中的Combobox。



有几种方法可以执行此操作：如果使用ShowDialog显示Form2 ，然后让OK按钮关闭Form2，并通过Form1代码中的属性获取新数据：

You display Form2 when the user checks RadioButton in Form1.
You enter data in the DataGridView and press OK. At this point you want to transfer information from the DataGridView to the Combobox in Form1.

There are a couple of ways to do this: If you use ShowDialog to display Form2, then just let the OK button close Form2, and pick up the new data via properties in teh Form1 code:

Dim f2 As New Form2()
f2.ShowDialog
' Use f2.Properties here to access the new values

如果你使用Show来显示新的Form2实例，那么它就更复杂了：你需要在Form2处理的Form2中创建一个事件，然后使用访问handler方法中的Form2属性。 sender 用于标识Form2实例的参数。

If you use Show to display the new Form2 instance, then it's more complex: you need to create an event in Form2 which Form1 handles, and then access the Form2 properties in the handler method, using the sender parameter to identify the Form2 instance.
