RefreshProperties.All not working as I want

[EdoardoNagliati]

Hello, I am encountering a problem with the RefreshProperties.All attribute of the propertyGrid, which I have reproduced below in a simplified manner: basically, it seems to me that the refresh is called only when interacting with the checkBox. However, if I change the value of this externally through a button, it seems to me that the refresh is not called. How can I solve this? Thank you for your kind attention

Grid>

public partial class MainWindow : Window { public PropGrid pGrid { get; private set; } public MainWindow() { InitializeComponent(); pGrid = new PropGrid(); this.DataContext = pGrid; } private void Button_Click(object sender, RoutedEventArgs e) { pGrid.CheckBox=false; } } public class PropGrid: INotifyPropertyChanged { public event PropertyChangedEventHandler PropertyChanged; protected virtual void OnPropertyChanged(string propertyName) { PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName)); } private bool _checkBox; [DisplayName("My CheckBox")] [Description("True=String is Browsable, False=String isn't Browsable")] [RefreshProperties(RefreshProperties.All)] public bool CheckBox { get { return _checkBox; } set { _checkBox = value; OnPropertyChanged(nameof(CheckBox)); PropertyDescriptor descriptor = TypeDescriptor.GetProperties(this.GetType())["String"]; BrowsableAttribute attribute = (BrowsableAttribute)descriptor.Attributes[typeof(BrowsableAttribute)]; var fieldToChange = attribute.GetType().GetFields(BindingFlags.Instance | BindingFlags.NonPublic).FirstOrDefault(a => a.Name.Contains("browsable", StringComparison.OrdinalIgnoreCase)); fieldToChange.SetValue(attribute, _checkBox ==true); } } [Browsable(false)] public string String{ get; set; } }; }

Hi,

The RefreshProperties attribute is used to refresh the propertyGrid when a property has this attribute.

In your sample, in the CheckBox property setter, I suggest you place your OnPropertyChanged( nameof( CheckBox ) ); at the end of the setter. This will let the browsable attribute be set before starting the refresh process. When you uncheck the CheckBox, the binding on the editor is resolved a bit later. But, when you modify a SelectedObject's property from code-behind, the OnPropertyChanged is executed right away, before the browsable attribute gets set.

Thank you
