Hi Pavel,

Thanks for the kind words 8)

1. It seems that's some kind of address in the Java Runtime memory space, and the default toString() implementation simply returns the type name + address. You can't use this as a persistent id because the object will be created at a different memory location when you load a diagram file. Instead, you could keep some long-int counter as a value of the Diagram's tag property, assign it to each item's tag when a new item is created, and increment it. Then you'll be sure that the item's tag is a unique value for this diagram.

2. SaveToXml() only saves the Shape IDs in the XML file. When you call LoadFromXml(), the control expects that shapes with IDs loaded from the XML have been already defined, or otherwise it falls back to the diagram's DefaultShape. Furthermore, shape definitions are not preserved in the view state, so you must define the shapes or load the shape library at each request to the page that calls LoadFromXml. We could add some option to store shape definitions in the view state, but NetDiagram already uses it heavily, and saving the shapes definitions there will add several more kilobytes to it.

I hope that helps,
Stoyan

Hi Pavel,

In addition to setting the LibraryLocation property (if using JavaApplet mode), you must also call ShapeLibrary.LoadFrom on the server side. You can find more information here:
http://mindfusion.eu/Forum/YaBB.pl?board=netdg_disc;action=display;num=123496172...

At this time shape libraries are not loaded automatically on the server side and you must call LoadFrom specifying a local file path on the server; we'll try to add some support for doing that automatically when a ShapeLibraryLocation is set to a relative path.

I hope that helps,
Stoyan

We'll add some support for loading shape libraries automatically in a couple of days.

Hi, Stoyan!
Thanks for your sample code, it works perfectly, but our project is a bit more complex.
We have a dropdown with all the diagram types.

The form contains a dropdown, a button, a diagramview and a shapelistbox.

When you change the dropdown value and click the button I want to load the shapes in the shape listbox and clear the diagram, allowing the user to start over a new diagram of other type.

I couldn't seem to make this even with your code (my best try was to be able to add the shapes to the shapelistbox but the default shapes are also there).

I did a lot of code with JDiagram but most of it was at the client side so I was thinking I know them well

I reviewed the documentation again but found nothing that can give me a clue on how to achieve my desired behaviour. Can you please help us again?

Does the ShapeListBox has something to do with the ShapeLibrary class?
If so - are the static methods responsible for loading the shapes into a shared location from where the shapelibrary / shape diagram can read them or instance is needed to be passed to some property perhaps?

Does it have some method to clear the items and then load the new?

Is the ShapeLibraryLocation responsible for the load / clear of the shapes inside the ShapeListBox?

Sorry for asking so much but I am eager to know everything as our project is already in a final phase, the logics are built, everything is almost ready, we are only missing the save / load functionality.

Any information will be highly appreciated.

Here is my latest try on the demo you sent.

Stoyan, thanks for your timely response.

Our client will probably acquire a copy of the controls tomorrow and we will target to have everything in place next week so it is not "for yesterday" symptom .

Just take your time and write back when possible.

It is a lot more important to me that the support is great - always responds back on time.

Thank you!

Hi, Stoyan!

Sorry I wasn't able to test your solution. I will do this now.

My case doesn't require me to have shapes from different libraries at the same time.

I need to save a diagram that have only shapes from the library that is currently loaded, so I think your solution would work.

I will test it and report back.

Thanks for helping us on time once again.

Hi Pavel,

Great to hear that 8)
