Notes

Checkboxes can have three states:

Examples

The following code in the CheckBox’s Action event handler checks the value of the CheckBox.

Because Checkbox is a three-state control, you can use the State property to get and set its value. The CheckedStates Enumeration is designed to get and set the values.

The following code sets the State property of a Checkbox to Indeterminate.

Because State is an enumeration, you cannot use the corresponding integer value for comparison. The following code shows how to use State in a Select Case statement.

See the entries for State and Value for additional examples of setting and getting Checkbox values. See also the CheckedStates Enumeration.
