在 Windows 窗体中,GroupBox 是一个容器,其中包含多个控件,这些控件相互关联。或者换句话说,GroupBox 是一组控件周围的框架显示,带有合适的可选标题。或者使用一个组框对一个组中的相关控件进行分类。在组框中,可以使用可见属性设置表单中组框的可见性。 如果该属性的值设置为真,则该组框在屏幕上可见,如果该属性的值设置为假,则该组框在屏幕上不可见。此属性的默认值为真。您可以通过两种不同的方式设置此属性:
1。设计时:设置组框可见性最简单的方法,如下步骤所示:
- 第一步:创建如下图所示的窗口表单: Visual Studio->File->New->Project->windows formpp
-
Step 2: Next, drag and drop the GroupBox control from the toolbox on the form as shown in the below image:
-
Step 3: After drag and drop you will go to the properties of the GroupBox and set the visibility of the GroupBox as shown in the below image:

2。运行时:比上面的方法稍微复杂一点。在此方法中,您可以在给定语法的帮助下以编程方式设置 GroupBox 控件的可见性:
public override string Text { get; set; }
以下步骤显示了如何动态设置组框的可见性:
-
步骤 1: 使用 GroupBox 类提供的 GroupBox()构造函数创建一个 GroupBox。
```cs // Creating a GroupBox GroupBox gbox = new GroupBox();
```
-
第二步:创建完 GroupBox 后,设置 GroupBox 类提供的 GroupBox 的 Visible 属性。
```cs // Setting visibility gbox.Visible = true;
```
-
Step 3: And last add this GroupBox control to the form and also add other controls on the GroupBox using the following statements:
```cs // Adding groupbox in the form this.Controls.Add(gbox);
and
// Adding this control // to the GroupBox gbox.Controls.Add(c2);
```
示例:
```cs using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Threading.Tasks; using System.Windows.Forms;
namespace WindowsFormsApp46 {
public partial class Form1 : Form {
public Form1() { InitializeComponent(); }
private void Form1_Load(object sender, EventArgs e) { // Creating and setting // properties of the GroupBox GroupBox gbox = new GroupBox(); gbox.Location = new Point(179, 145); gbox.Text = "Select Gender"; gbox.Name = "Mybox"; gbox.Font = new Font("Colonna MT", 12); gbox.Visible = true; gbox.AutoSize = true; gbox.AutoSizeMode = AutoSizeMode.GrowAndShrink;
// Adding groupbox in the form this.Controls.Add(gbox);
// Creating and setting // properties of the CheckBox CheckBox c1 = new CheckBox(); c1.Location = new Point(40, 42); c1.Size = new Size(69, 20); c1.Text = "Male";
// Adding this control // to the GroupBox gbox.Controls.Add(c1);
// Creating and setting // properties of the CheckBox CheckBox c2 = new CheckBox(); c2.Location = new Point(183, 39); c2.Size = new Size(79, 20); c2.Text = "Female";
// Adding this control // to the GroupBox gbox.Controls.Add(c2); } } } ```
