Description
Indicates whether all the buttons in a given group can be up at the same time.
Set AllowAllUp to true to allow all buttons in a given group to be deselected simultaneously. If AllowAllUp is false, then the button group in question must have exactly one button selected at any given time. Groups of buttons designed this way are sometimes called radio buttons.
