PropertyGrid loose focus after RefreshProperties.All

Question

I am using WPF Xceed.Wpf.Toolkit.PropertyGrid to show properties of my object for user to edit.

My class property is as shown below:

private double height;

[Browsable(true)]
[RefreshProperties(RefreshProperties.All)] 
public double Height
{
    get
    {
        return height;
    }

    set
    {            
        bodymass = height * 10;//Some other property
        _height= value;
    }
}

For each key press, set() is called and the grid row is loosing its focus due to RefreshProperties.All. Due to that, it is not possible to continuously type values to the grid row.

Is it possible to keep focus on the same property I was type in?

Or at least, it there a way to instruct the set() to be called only when user click enter/ loose focus?

Get rid of the RefreshProperties attribute, implement the INotifyPropertyChanged interface and raise the PropertyChanged event for all properties that you want to refresh in the setter of the Height property:

public class MyObject : INotifyPropertyChanged
{
    private double height;

    [Browsable(true)]
    public double Height
    {
        get
        {
            return height;
        }

        set
        {
            height = value;
            Test = height.ToString(); //this refreshes Test
        }
    }

    private string _test;
    public string Test
    {
        get { return _test; }
        set { _test = value; NotifyPropertyChanged(); }
    }

    public event PropertyChangedEventHandler PropertyChanged;
    private void NotifyPropertyChanged([CallerMemberName] String propertyName = "")
    {
        if (PropertyChanged != null)
            PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
    }
}

<xctk:PropertyGrid x:Name="_propertyGrid" Width="450" Margin="10" AutoGenerateProperties="False">
    <xctk:PropertyGrid.PropertyDefinitions>
        <xctk:PropertyDefinition TargetProperties="Height" />
        <xctk:PropertyDefinition TargetProperties="Test" />
    </xctk:PropertyGrid.PropertyDefinitions>
</xctk:PropertyGrid>

Thanks very much. But in this case I have to create so many backing variables for all other properties. Correct? — OrionSoftTechnologiesSydney, Apr 20 '17 at 06:24
No, you could refresh any auto-implemented property by calling the NotifyPropertyChanged method and passing the name of the property that you want to update to it, e.g. NotifyPropertyChanged("TheNameOfThePropertyToUpdate"); — mm8, Apr 20 '17 at 09:49
You should also be able to refresh all data bound properties by passing an empty string or null to the NotifyPropertyChanged method. — mm8, Apr 20 '17 at 09:52
