Answer 1

启用菜单项的AutoCheck属性(property)。链接引用将其描述为:

AutoCheck

Indicates whether the menu item's checked state toggles automatically when the item is clicked.

When AutoCheck is true, then every time the menu item is clicked, the value of the Checked property toggles automatically before the OnClick event occurs. When AutoCheck is false, the application must explicitly set the value of the Checked property (for example, in an OnClick event handler).
