Displays the selection state of an item.
Remarks
Use a CheckBox to give the user a choice between two values such as Yes/No, True/False, or On/Off. When the user selects a CheckBox, it displays a special mark (such as an X) and its current setting is Yes, True, or On; if the user does not select the CheckBox, it is empty and its setting is No, False, or Off. Depending on the value of the TripleState property, a CheckBox can also have a null value.
If a CheckBox is bound to a data source, changing the setting changes the value of that source. A disabled CheckBox shows the current value, but is dimmed and does not allow changes to the value from the user interface.
You can also use check boxes inside a group box to select one or more of a group of related items. For example, you can create an order form that contains a list of available items, with a CheckBox preceding each item. The user can select a particular item or items by checking the corresponding CheckBox.
The default property of a CheckBox is the Value property.
The default event of a CheckBox is the Click event.
Note The ListBox also lets you put a check mark by selected options. Depending on your application, you can use the ListBox instead of using a group of CheckBox controls.
