PopupButton - InvalidateRequerySuggested

Ribbon for WPF Forum

Posted 12 years ago by Ray Huger

My ribbon has a PopupButton with two commands. When either of the commands CanExecute the PopupButton is enabled. When conditions change that would make one of the commands have CanExecute true I call CommandManager.InvalidateRequerySuggested(). That does not cause the commands' CanExecuteRoutedEventHandlers to fire. Only when I change the SelectedTab for the ribbon do I get the button to enable.

Any suggestions?

Hi Ray,

You can set a PopupButton.Command and tie it to a command whose CanExecute handler just returns whether at least one of the child commands can execute. That should govern the enabled state of the PopupButton.
