MenuItem.RadioCheck Property

Gets or sets a value indicating whether the MenuItem, if checked, displays a radio-button instead of a check mark.

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

member RadioCheck : bool with get, set

Property Value

Type: System.Boolean
true if a radio-button is to be used instead of a check mark; false if the standard check mark is to be displayed when the menu item is checked. The default is false.

Check marks do not necessarily imply a mutually exclusive state for a group of menu items. You can use this property to indicate to the user that the check mark of a menu item is mutually exclusive.

The following code example uses the Checked property to change the state of an application. In the example, a group of menu items are provided that are used to specify the color for the text in an TextBox control. In the example, the event handler provided is used by the Click event of the three menu items. Each menu item specifies a color, menuItemRed, menuItemGreen, or menuItemBlue. The event handler determines which menu item was clicked, places a checkmark to the selected menu item, and changes the text color of the form's TextBox control, named textBox1. The example also uses the RadioCheck property to demonstrate how a radio-button check is used to show menu items that are mutually exclusive. This example requires that the System.Drawing namespace has been added to the form that contains this code.
