Q2 2012 Diagram save method doesnt save the shape background

[hal broad]

I just installed Q2 2012 and now the diagram doesnt save the background of the shapes. 
The background was properly saved in the previous version. I have included the diagram config and the 
output file. the docs say Background is automatically saved but I am not getting it. I tried using the 
serialize/deserialize methods but that just gives me a blank background for the shapes. 
How can I get the background

Hi,

 For the Q2 release, we have made some changes around the serialization mechanism. The visual properties like Background, Foreground, etc. are saved only when they are manually set (with a local value). This was needed to be consistent with the theming mechanism. For example, if you copy a shape in one theme and paste it in a diagram with a different theme, it should use the settings of the latter theme. In this case, setting these properties through a style (style's setter).

However, if you do want to save these properties even though they are not locally set, you can handle the ShapeSerialized event.

Kind regards,

Would you provide an example of how to do this for a background of a shape?
Thanks.

Hi,

 Setting the background locally, meaning setting it manually :
<telerik:RadDiagramShape Background="Red" />
or
shape.Background = Brushes.Red.

The other option is use a shape style, using the RadDiagram.ShapeStyle property. This way, even though the background is not serialized, it will be the same when deserialized, because of the style.
