Question

编程新手的困境......在我的程序中。

我正在计算和显示一个人维持当前体重所需的卡路里数。我有2套2 radioButtons：1套针对性别，男性或女性，另一套针对其活动率，有效或无效。

使用两组不同的radioButtons，每个都应该可以选择一个，但是一次只能选择一个单选按钮，如何告诉程序处理两组单选按钮分别？

Answer 1

单选按钮分组工作。用容器和你的好东西分开它们。

Answer 2

你应该使用GroupBoxes将一组radiobuttons放在一个groupbox中，另一组放在另一个Group框内

通过这种方式，每组radiobutton都与另一组相隔离并按预期工作

以下代码只是手动表单构建的一个示例，与设计人员一起使用将在InitializeComponent方法中为您创建此代码的等效代码。请注意两个radiobutton集是如何是不同容器（子组）的子节点

' A generic form
Dim f as Form = new Form()
f.Size = new Size(300, 500)

' Create a Group box
Dim b1 as GroupBox = new GroupBox()
b1.Text = "Gender"
b1.Location = new Point(0,0)

' Create two radiobutton for Gender
Dim r1 as RadioButton = new RadioButton()
r1.Text = "Male"
r1.Location = new Point(5,15)
Dim r2 As RadioButton = new RadioButton()
r2.Text = "Female"
r2.Location = new Point(5, 40)

' Add the two radiobuttons to the GroupBox control collection
b1.Controls.AddRange(new Control() {r1, r2})

' Repeat for the second set of radiobuttons
Dim b2 as GroupBox = new GroupBox()
b2.Text = "Activity Rate"
b2.Location = new Point(0,100)
Dim r3 As RadioButton = new RadioButton()
r3.Text = "Active"
r3.Location = new Point(5,15)
Dim r4 as RadioButton = new RadioButton()
r4.Text = "Inactive"
r4.Location = new Point(5,40)
b2.Controls.AddRange(new Control() {r3, r4})

' Finally add the GroupBoxes to the Form ControlsCollection
f.Controls.AddRange(new Control() {b1, b2})

f.ShowDialog()

分别处理两套
