GroupBox Constructor

Initializes a new instance of the GroupBox class.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

public GroupBox()

By default, the TabStop property is set to false when a new GroupBox is created. The group box has an initial height of 100 pixels and width of 200 pixels.

The following code example instantiates and creates a GroupBox and two RadioButton controls. The option buttons (also known as radio buttons) are added to the group box, and the group box is added to the Form.

private void InitializeMyGroupBox()
{
   // Create and initialize a GroupBox and a Button control.
            GroupBox groupBox1 = new GroupBox();
            Button button1 = new Button();
            button1.Location = new Point(20,10);

            // Set the FlatStyle of the GroupBox.
            groupBox1.FlatStyle = FlatStyle.Flat;

            // Add the Button to the GroupBox.
            groupBox1.Controls.Add(button1);

            // Add the GroupBox to the Form.
            Controls.Add(groupBox1);

            // Create and initialize a GroupBox and a Button control.
            GroupBox groupBox2 = new GroupBox();
            Button button2 = new Button();
            button2.Location = new Point(20, 10);
            groupBox2.Location = new Point(0, 120);

            // Set the FlatStyle of the GroupBox.
            groupBox2.FlatStyle = FlatStyle.Standard;

            // Add the Button to the GroupBox.
            groupBox2.Controls.Add(button2);

            // Add the GroupBox to the Form.
            Controls.Add(groupBox2);
}
