範例

以下範例程式碼建立 並 GroupBox 設定其一些常見屬性。 範例中會建立 ， TextBox 並將 置 Location 於群組框中。 接著，它設定 Text 群組框的屬性，並將群組框停靠到表單的頂端。 最後，它會透過將屬性false設Enabled為 來停用群組框，這會使群組框內的所有控制項被停用。

   // 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

備註

由於類別 Point 是值型別（Structure 在 Visual Basic 中，在 struct Visual C# 中），因此以值回傳，也就是存取該屬性會回傳控制項左上角的副本。 因此，調整X從該屬性回傳的 or 屬性PointY不會影響Left控制的 、 Right、 Top或 Bottom 屬性值。 要調整這些屬性，請分別設定每個屬性值，或用新的 Point設定該Location屬性。

若 Control 為 Form，則屬性 Location 值代表螢幕座標的 Form 左上角。
