CheckBox Constructor

Initializes a new instance of the CheckBox class.

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

public CheckBox()

By default, when a new CheckBox is instantiated, AutoCheck is set to true, Checked is set to false, and Appearance is set to Normal.

The following code example creates and initializes a CheckBox, gives it the appearance of a toggle button, sets AutoCheck to false, and adds it to a Form.

public void InstantiateMyCheckBox()
 {
    // Create and initialize a CheckBox.   
    CheckBox checkBox1 = new CheckBox(); 

    // Make the check box control appear as a toggle button.
    checkBox1.Appearance = Appearance.Button;

    // Turn off the update of the display on the click of the control.
    checkBox1.AutoCheck = false;

    // Add the check box control to the form.
    Controls.Add(checkBox1);
 }
