object.
public MainWindow()
{
InitializeComponent();
SerializationService.Default.ItemSerializing += Default_ItemSerializing;
}
private void Default_ItemSerializing(object sender, SerializationEventArgs<IDiagramItem> e)
{
var shape = e.Entity as RadDiagramShape;
if (shape != null && shape.ParentOfType<RadDiagramToolbox>() != null)
{
e.SerializationInfo["Background"] = new SolidColorBrush((Color)ColorConverter.ConvertFromString("#8EC251"));
e.SerializationInfo["BorderBrush"] = new SolidColorBrush((Color)ColorConverter.ConvertFromString("#8EC251"));
}
}
RadDiagramToolBox.Resources

controls.
<telerik:RadDiagramToolbox.Resources>
<Style TargetType="telerik:RadDiagramShape">
<Setter Property="Background" Value="#8EC251" />
<Setter Property="BorderBrush" Value="#8EC251" />
</Style>
