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

member AutoCheck : bool with get, set

Property Value

Type: System.Boolean

true if the Checked value and the appearance of the control automatically change on the Click event; otherwise, false. The default value is true.

If the Checked value is set to false, the RadioButton portion of the control must be checked in code in the Click event handler. In addition, if the RadioButton is part of a RadioButton control group, this property ensures that only one of the controls is checked at a given time.

If the AutoCheck property is set to false, a group of RadioButton controls will not act as a mutually exclusive group and the Checked property must be updated in code.

The following code example creates and initializes a RadioButton, gives it the appearance of a toggle control, sets its AutoCheck property to false, and adds it to a Form.
