示例

下面的代码示例创建一个GroupBox并设置它的一些公共属性。The following code example creates a GroupBox and sets some of its common properties. 该示例创建一个TextBox ,并在Location组框中设置它。The example creates a TextBox and sets its Location within the group box. 接下来,它设置Text组框的属性,并将组框停靠到窗体的顶部。Next, it sets the Text property of the group box, and docks the group box to the top of the form. 最后,它通过将Enabled属性设置为来false禁用分组框,这将导致禁用组框中包含的所有控件。Lastly, it disables the group box by setting the Enabled property to false, which causes all controls contained within the group box to be disabled.

   // 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

每个派生类都以不同的方式使用控件的属性。TextThe Text property of the control is used differently by each derived class. 例如Text ,的Form属性显示在窗体顶部的标题栏中,在字符计数中相当小,通常显示应用程序或文档名称。For example the Text property of a Form is displayed in the title bar at the top of the form, is fairly small in character count, and usually displays the application or document name. 但是, Text的属性RichTextBox可能很大,并且可以包含用于设置文本格式的大量非可视字符。However, the Text property of a RichTextBox can be large and can include numerous nonvisual characters used to format the text. 例如, RichTextBox可以通过Font调整属性来设置中显示的文本的格式,也可以通过添加空格或制表符来使文本对齐。For example, the text displayed in a RichTextBox can be formatted by adjusting the Font properties, or by the addition of spaces or tab characters to align the text.

继承者说明

当在派生Text类中重写属性时, 使用基类的Text属性扩展基实现。When overriding the Text property in a derived class, use the base class's Text property to extend the base implementation. 否则, 必须提供所有实现。Otherwise, you must provide all the implementation. 不需要重写get Text属性的和set访问器; 如果需要,只能重写一个。You are not required to override both the get and set accessors of the Text property; you can override only one if needed.
