I try set a guid or text (string) on my own control on xaml, but not work.

Code:

public class MyLabel : Label
    {

        [Category("Guid")]
        //[DesignerSerializationVisibility(DesignerSerializationVisibility.Visible)]
        public static DependencyProperty MyControlGuidProperty =
            DependencyProperty.Register("MyControlGuid", typeof(Guid), typeof(MyLabel));

        [Category("Guid")]        
        public Guid MyControlGuid
        {
            get
            {

                return (Guid)GetValue(MyControlGuidProperty);
            }
            set
            {
                SetValue(MyControlGuidProperty, value);
            }
        }

        public MyLabel()
            : base()
        {
            SetValue(MyControlGuidProperty, Guid.NewGuid());
        }

    }

But doesn't works. When i drag the new control form toolbox to MainWindows.xaml - generated the MyLabel but not MyControlGuid on Xaml. Under properties have the MyLabel a valied guid.

Only when i click at box at the end of the MyControlGuid - i can choose "convert to local value" and the guid was set it on xaml.

I get only

<local:MyLabel Content="MyLabel" HorizontalAlignment="Left" Margin="193,79,0,0" VerticalAlignment="Top"/>

but i want

<local:MyLabel Content="MyLabel" HorizontalAlignment="Left" Margin="193,79,0,0" VerticalAlignment="Top" MyControlGuid="6c090537-4a06-41d5-a0ea-6d3112df0f77"/>

this i get only over WPF Property Grid and click convert to local value.


What i must to do for that in code on my control (convert to local value)?

What I have tried:

I have try with the Attribute

[DesignerSerializationVisibility(DesignerSerializationVisibility.Visible)]

but not works.

I have try PropertyChangedCallback and CoerceValueCallback - not works too.
