Hi,
I would like to be able to trigger an event when a boolean changes value to false. I know how to trigger the event when the boolean changes value but any guidance as to how to only trigger event when boolean is false?
It was actually very simple. Here is how I did it:
private bool isMonitoring = false; private bool IsMonitoring { get { return isMonitoring; } set { if (isMonitoring != value) { isMonitoring = value; OnPropertyChanged(nameof(IsMonitoring)); // trigger action if set to false if (isMonitoring == false) { PrintLogLine("Monitoring bool changed to false."); } } } } public event PropertyChangedEventHandler PropertyChanged; protected virtual void OnPropertyChanged([CallerMemberName] string propertyName = null) { PropertyChangedEventHandler handler = PropertyChanged; if (handler != null) { handler(this, new PropertyChangedEventArgs(propertyName)); } }
