<XtraSerializableProperty>
Public Overridable Property RefreshOnSelectedObjectChanges As Boolean

Property Value

Property Paths

You can access this nested property as listed below:

Object Type	Path to RefreshOnSelectedObjectChanges
PropertyGridControl	.OptionsBehavior .RefreshOnSelectedObjectChanges

Remarks

If the selected object (see SelectedObject, SelectedObjects) supports the INotifyPropertyChanged interface, the control automatically updates its content when a property changes. Set the RefreshOnSelectedObjectChanges property to false to prevent the automatic updates. To refresh the content manually, call the Refresh() or UpdateRows() method.

Example

The code below shows how the INotifyPropertyChanged interface can be implemented. Since the RefreshOnSelectedObjectChanges property is set to false, the control does not update the content when the selected object changes.

C#

propertyGridControl1.SelectedObject = new MyObject();
propertyGridControl1.OptionsBehavior.RefreshOnSelectedObjectChanges = false;

public class MyObject : INotifyPropertyChanged {
    object myProperty;
    public object MyProperty {
        get {
            return myProperty;
        }
        set {
            myProperty = value;
            PropertyChanged?.Invoke(this, new PropertyChangedEventArgs("MyProperty"));
        }
    }
    public event PropertyChangedEventHandler PropertyChanged;
}

VB.NET

propertyGridControl1.SelectedObject = New MyObject()
propertyGridControl1.OptionsBehavior.RefreshOnSelectedObjectChanges = False

Public Class MyObject
    Implements INotifyPropertyChanged
    Private fMyProperty As Object
    Public Property MyProperty() As Object
        Get
            Return fMyProperty
        End Get
        Set(ByVal value As Object)
            fMyProperty = value
            PropertyChangedEvent?.Invoke(Me, New PropertyChangedEventArgs("MyProperty"))
        End Set
    End Property
    Public Event PropertyChanged As PropertyChangedEventHandler Implements INotifyPropertyChanged.PropertyChanged
End Class
