示例

下面的代码示例创建并 GroupBox 设置其一些常见属性。 该示例在 TextBox 组框中创建并设置它 Location 。 接下来，它将组框的属性设置为 Text 组框，并将组框停靠在窗体顶部。 最后，它通过将属性false设置为Enabled禁用组框来禁用组框，这将导致禁用组框中包含的所有控件。

   // Add a GroupBox to a form and set some of its common properties.
private:
   void AddMyGroupBox()
   {
      // Create a GroupBox and add a TextBox to it.
      GroupBox^ groupBox1 = gcnew GroupBox;
      TextBox^ textBox1 = gcnew TextBox;
      textBox1->Location = Point(15,15);
      groupBox1->Controls->Add( textBox1 );

      // Set the Text and Dock properties of the GroupBox.
      groupBox1->Text = "MyGroupBox";
      groupBox1->Dock = DockStyle::Top;

      // Disable the GroupBox (which disables all its child controls)
      groupBox1->Enabled = false;

      // Add the Groupbox to the form.
      this->Controls->Add( groupBox1 );
   }

// Add a GroupBox to a form and set some of its common properties.
private void AddMyGroupBox()
{
   // Create a GroupBox and add a TextBox to it.
   GroupBox groupBox1 = new GroupBox();
   TextBox textBox1 = new TextBox();
   textBox1.Location = new Point(15, 15);
   groupBox1.Controls.Add(textBox1);

   // Set the Text and Dock properties of the GroupBox.
   groupBox1.Text = "MyGroupBox";
   groupBox1.Dock = DockStyle.Top;

   // Disable the GroupBox (which disables all its child controls)
   groupBox1.Enabled = false;

   // Add the Groupbox to the form.
   this.Controls.Add(groupBox1);
}

' Add a GroupBox to a form and set some of its common properties.
Private Sub AddMyGroupBox()
   ' Create a GroupBox and add a TextBox to it.
   Dim groupBox1 As New GroupBox()
   Dim textBox1 As New TextBox()
   textBox1.Location = New Point(15, 15)
   groupBox1.Controls.Add(textBox1)
   
   ' Set the Text and Dock properties of the GroupBox.
   groupBox1.Text = "MyGroupBox"
   groupBox1.Dock = DockStyle.Top
   
   ' Disable the GroupBox (which disables all its child controls)
   groupBox1.Enabled = False
   
   ' Add the Groupbox to the form.
   Me.Controls.Add(groupBox1)
End Sub

注解

控件 Text 的属性由每个派生类使用不同的属性。 例如， Text 属性显示在窗体顶部的 Form 标题栏中，字符计数相当小，通常显示应用程序或文档名称。 但是，属性RichTextBox可能很大，Text并且可以包含用于设置文本格式的众多非visual 字符。 例如，可以通过调整属性或添加空格或制表符来对齐Font文本来设置以格式显示RichTextBox的文本。

继承者说明

重写 Text 派生类中的属性时，请使用基类的属性 Text 扩展基实现。 否则，必须提供所有实现。 无需同时替代 get 属性和 set 访问器 Text ;仅在需要时可以替代一个。
