	Unfortunately that's not supported. You can assign arbitrary objects to the Tag property, but the SerializeTag handler must encode them as simple strings when submitting to the server. E.g. you might concatenate all attributes of an object into a string containing comma-delimited list. Stoyan

	Can I change the type of the node?, I would like to do something like: <Tag Type="MyType">MyNodeContent</Tag>

	Sorry, what's exposed to the applet works only with strings at this time. If you know some Java you could implement DiagramListener.serializeTag / deserializeTag methods to get access to the XML DOM.

	Are you using JavaApplet mode and need to access the tags on the client side, or you only need their values preserved between post-backs?

	I'm sorry, I believe I post in the wrong thread, but I believe you can still help me, I'm not using JavaApplet at all, I'm just have my windows app build in C#, and what I need is to save the project to an xml but with some custom nodes, I figure out that cannot be done, so I found that I could use the <Tag> node to do that, so, in order to do custom node I tryng to set a custom Type Tag. I doing this: diagram.Tag="MyCustomContent"; but also I need to idenfied that node, and with the standard type that use numbers it's almost like I'm not customizing at all... what I need to do is set a custom type, like I posted before: <Tag Type="MyType">MyNodeContent</Tag> I hope you can help me. thanks.

	Ok, that can be done by handling the SerializeTag event. Note that it is raised only if DiagramItem.Tag is not null. You must also set e.Handled = true to keep your custom XML, or otherwise the control would overwrite it using the built-in serialization. You can find sample code in the Diagram.SerializeTag Event help topic. Args.Representation would point to the "Tag" Xml node, and you could set attributes on it too. Another possibility is to use a derived node type and override its SaveToXml method. This would let you add child elements directly under <Node>, instead of deeper in the hierarchy under <Tag>. I hope that helps, Stoyan
