We're trying to handle the SerializeTag event on a Wpf Diagram so that we can perform custom serialization of an object that is assigned to the diagram's Tag property. But the SerializeTag event is not firing. Here's how we're handling the event:

[code]
private void MenuItem_Click1(object sender, RoutedEventArgs e)


{



currentDiagram.SerializeTag += new SerializeTagEventHandler(currentDiagram_SerializeTag);



currentDiagram.SaveToXml(@"c:\Test.xml");


}



void currentDiagram_SerializeTag(object sender, SerializeTagEventArgs e)


{



e.Handled = true;



DiagramProperties dp = e.Tag as DiagramProperties;



if (dp != null)



{




string xml = dp.SerializeState();




XmlNode repNode = e.Context.XmlDocument.CreateTextNode(xml);




e.Representation.AppendChild(repNode);



}


}
[/code]

DiagramProperties is an instance of a custom class that stores metadata about our diagram.

Thanks,

Great. Thanks. This would be a very helpful for serializing diagram metadata.

Can you also get this feature into the Silverlight diagram component?

Stoyo,

We're using the beta now, and the Serialize/DeserializeTag events are firing correctly for the diagram's tag. However, it doesn't fire for custom UIElements that have tags.

Stoyan,

I think we have a workaround for this issue. We're now serializing the tag of the containing DiagramNodeAdapter instead of our custom UIElement. Works like a charm.

Thanks!
